Does Hair Grow Back After Falling Out From Roots?
You likely want a clear, evidence-based answer to whether hair that comes out from the root can regrow. This article explains the biology, the causes of root-level shedding, how clinicians diagnose the problem, what treatments work, and the realistic timelines and outcomes you can expect.
How hair grows: the follicle and the hair shaft
Understanding whether hair can regrow begins with knowing how follicles function. Hair is produced by follicles in the dermis; the visible hair is the shaft, and the portion you see as the “root” is the hair bulb and attached structures that once fed the shaft.
The hair follicle: anatomy and function
The follicle contains the dermal papilla, matrix cells, and an outer root sheath that coordinate growth. These structures supply nutrients and signals that drive new hair production during the growth phase.
The hair growth cycle: anagen (growth)
Anagen is the active growth phase that lasts months to years depending on body site and genetics. While you are in anagen, the follicle is highly active and the hair shaft is anchored strongly in the bulb.
The hair growth cycle: catagen (transition)
Catagen is a short transitional phase lasting a few weeks during which the follicle shrinks and hair production pauses. This is not a time of permanent destruction; the follicle usually remains intact.
The hair growth cycle: telogen (resting) and exogen (shedding)
Telogen is a resting phase lasting a few months, followed by exogen when the club hair sheds and a new anagen hair may begin. When you find hairs with a small, white club-like bulb after shedding, that typically means a telogen hair has naturally released from the follicle.
Why hair falls out from the roots
Hair can detach at the root for many reasons, and the likelihood of regrowth depends on whether the follicle remains healthy. Some causes temporarily interrupt the growth cycle, while others permanently damage follicular structures.
Non-scarring causes versus scarring causes
Non-scarring (non-cicatricial) causes interrupt or reset the hair cycle but leave the follicle capable of regeneration. Scarring (cicatricial) causes destroy the follicle or replace it with fibrous tissue, which typically prevents regrowth.
Telogen effluvium
Telogen effluvium is a common, reversible cause where stressors push more hairs into telogen, causing diffuse shedding about 2–3 months after the trigger. Because the follicles remain structurally intact, you can expect gradual regrowth once the trigger resolves.
Anagen effluvium
Anagen effluvium occurs when an acute insult — most classically chemotherapy — stops matrix cell mitosis and causes rapid hair loss during the growth phase. Regrowth is common if the insult is temporary and the follicle survives; it often begins within weeks to months after the insult ends.
Alopecia areata (autoimmune)
Alopecia areata is an autoimmune condition where immune cells attack the follicle, causing round patches of smooth baldness with hairs that can fall out suddenly. Many people experience spontaneous regrowth, though the course is unpredictable and relapses can occur.
Traction alopecia
Traction alopecia results from chronic mechanical tension on follicles due to hairstyles that pull the hair tightly. Early-stage traction alopecia is reversible after changing hair practices; long-standing traction with follicular scarring can become permanent.
Scarring alopecias (cicatricial)
Scarring alopecias such as lichen planopilaris, frontal fibrosing alopecia, and folliculitis decalvans destroy the follicular epithelium and replace it with scar tissue. When scarring is established, hair generally does not regrow in the affected areas.
Infections, burns, and inflammatory injury
Severe infections, hot burns, or intense inflammatory conditions can also destroy follicles at the dermal level. If the follicular stem cells and dermal papilla are lost, regrowth will be unlikely without surgical intervention.
How to tell whether the follicle is intact
You can often make an initial assessment from the appearance of the scalp and the shed hair. Clinical and dermatoscopic signs help determine whether regrowth is possible.
What a pulled hair looks like
Hairs that come out easily with a soft, white club-shaped bulb usually represent telogen hairs and suggest the follicle is intact. In contrast, hairs with an empty translucent shaft or broken fragments may indicate structural damage or fragility.
Scalp signs of scarring versus non-scarring
If the scalp has shiny, smooth, or atrophic skin with loss of follicular openings, that suggests scarring and a lower chance of natural regrowth. If follicular openings are present and the scalp appears healthy, follicles are more likely viable.

Diagnostic approach: how clinicians evaluate root-level hair loss
When you present with hair falling from the roots, a clinician will take a systematic approach that includes history, physical exam, tests, and sometimes biopsy. Accurate diagnosis guides realistic prognosis and treatment.
History: timing, triggers, medications, and patterns
Your clinician will ask about onset, duration, recent illnesses, medications, styling practices, family history, and systemic symptoms. These details can distinguish telogen effluvium, traction, medication-induced loss, androgenetic patterns, or autoimmune causes.
Physical exam and hair pull test
The hair pull test involves gently pulling small handfuls of hair in different scalp areas; more than a few hairs per pull can indicate active shedding. The distribution of thinning — diffuse versus patchy versus frontal — also helps narrow the cause.
Trichoscopy (dermatoscopic exam)
Trichoscopy allows in-office visualization of follicular openings, hair shaft morphology, and perifollicular inflammation without biopsy. It can reveal features characteristic of alopecia areata, androgenetic changes, or scarring disorders.
Laboratory testing
Blood tests may include thyroid function, ferritin, vitamin D, CBC, and hormone panels when indicated by your history. Treating underlying deficiencies or endocrine disease often improves hair regrowth potential.
Scalp biopsy
When diagnosis remains unclear, a scalp biopsy provides histological confirmation and distinguishes scarring from non-scarring processes. The biopsy is a small procedure that yields information on inflammation type, fibrosis, and follicular architecture.
Prognosis: permanent versus temporary hair loss
Your chance of regrowth depends primarily on whether the follicle remains viable and whether the underlying trigger can be addressed. Many types of root-level shedding are reversible if identified and treated early; scarring conditions have far less favorable natural recovery.
Scenarios with good chances of regrowth
If the cause is telogen effluvium, anagen effluvium with recovery, early alopecia areata, or traction without scarring, you have a strong likelihood of regrowth over several months. Treatments and supportive care often accelerate and optimize recovery.
Scenarios with poor chances without intervention
Established cicatricial alopecias, full-thickness burns, or long-standing traction that has caused follicular destruction usually will not regrow spontaneously. In those cases, surgical restoration such as hair transplantation or grafting techniques may be required for cosmetic improvement.
Typical timelines for regrowth by condition
You likely want concrete expectations for when new hair will appear. The following table summarizes average timelines for regrowth in common causes of root-level hair loss.
| Condition | Typical regrowth timeline | Notes |
|---|---|---|
| Telogen effluvium | 3–6 months for visible improvement; full density may take 6–12 months | Remove trigger; expect gradual thickening as follicles re-enter anagen. |
| Anagen effluvium (chemo) | 1–4 months after treatment stops | Regrowth often begins within weeks; texture/color changes are common initially. |
| Alopecia areata (non-extensive) | Weeks to months; variable | Many cases remit spontaneously; topical/injectable steroids can speed regrowth. |
| Traction alopecia (early) | Months after stopping traction; improvement may continue >1 year | Early intervention yields best results; scarring predicts poorer outcome. |
| Androgenetic alopecia | Slow; months to years with medical therapy | Treatments slow progression and increase density but require ongoing use for maintenance. |
| Scarring alopecia | Usually none without surgical intervention | If biopsy shows fibrosis and loss of follicles, natural regrowth is unlikely. |
Treatments that promote regrowth when follicles are viable
When follicles are intact, multiple therapies can encourage or accelerate regrowth. Your choice will depend on the diagnosis, severity, budget, and tolerance for medications or procedures.
Address the underlying cause
Treating or removing triggers — correcting iron deficiency, treating thyroid disease, stopping offending medications, or changing hairstyles — is the first step. Once the trigger is resolved, many follicles resume normal cycling and growth.
Topical minoxidil
Minoxidil is an FDA-approved topical agent that prolongs anagen and increases blood flow to the follicle. It is effective in many forms of non-scarring hair loss and requires continuous use for sustained benefits.
Oral finasteride (men)
Finasteride inhibits the conversion of testosterone to dihydrotestosterone (DHT), which drives male pattern hair loss. It has strong evidence for halting progression and promoting regrowth in men, but it is not approved for women of childbearing potential and carries potential sexual side effects.
Corticosteroids (topical or intralesional)
For autoimmune forms such as alopecia areata, corticosteroids can suppress the immune attack on follicles and promote regrowth. Intralesional steroid injections into affected patches often produce faster localized results.
Platelet-rich plasma (PRP)
PRP uses concentrated platelets from your own blood to deliver growth factors to the scalp and stimulate follicular activity. Many studies report improved hair density and thickness; results vary and multiple sessions are usually needed.
Low-level laser therapy (LLLT)
LLLT devices deliver light energy that can stimulate cellular activity in the follicle. Clinical trials show modest improvements in hair density for some individuals and it is typically combined with other therapies.
Microneedling with topical agents
Microneedling creates micro-injuries that promote growth factor release and increase topical absorption; combining it with minoxidil or PRP can enhance results. Several studies support improved regrowth when used in conjunction with established treatments.
Hair transplantation
When follicles are lost or when medical therapies are insufficient, hair transplantation relocates healthy follicles from donor sites to balding areas. Modern follicular unit extraction (FUE) and transplantation provide permanent cosmetic restoration but are surgical and require recovery time.

Regenerative and stem-cell–based approaches
You may be interested in newer regenerative strategies designed to reactivate dormant follicles. These therapies focus on stimulating the follicular stem cell niche and improving the local microenvironment.
Platelet-rich plasma and growth factors
As noted, PRP delivers autologous growth factors that can promote cellular proliferation and vascular support. It is minimally invasive and often used in series of monthly treatments initially.
Stem cell growth factor therapy (Beyond Stem Cells and similar)
Stem cell growth factor therapy uses concentrated growth factors derived from cellular sources to reactivate dormant follicles and enhance the scalp environment. Providers such as Beyond Stem Cells report that this approach is minimally invasive, virtually pain-free, costs about half that of traditional transplants, and aims to stimulate natural hair growth without the need for ongoing medication or repeated surgery.
How these therapies differ from transplants
Regenerative therapies aim to improve the function of existing follicles and promote new growth from viable follicles, whereas transplantation introduces new follicles surgically. In many cases regenerative approaches can be an alternative or complement to surgical options, especially when the goal is to avoid invasive procedures.
Evidence and expectations
Many studies demonstrate promising outcomes for PRP and growth factor therapies, though responses vary by individual, diagnosis, and treatment protocol. You should expect an incremental improvement over months, and providers often recommend combination therapies for optimal results.
Hair restoration considerations for men
If you are a man concerned about hair falling from the roots, androgenetic alopecia (male pattern baldness) accounts for the majority of progressive, patterned loss. Treatments that address DHT, improve follicle health, or replace lost follicles are the mainstays of care for men.
Prevalence and typical patterns
Over 50% of men over age 50 experience male pattern hair loss, and most men will have some thinning in their lifetime. Patterned loss shows predictable frontal and vertex thinning, which helps guide medical or surgical strategies.
Medical and regenerative options for men
Finasteride and topical minoxidil remain the first-line medical therapies for many men, with surgical transplant and emerging regenerative treatments available for more advanced cases. Regenerative options like stem cell growth factor therapy may reactivate dormant follicles and provide natural-appearing results with less downtime than surgery, according to recent clinical reports.
Hair restoration considerations for women
If you are a woman, your pattern and causes of hair loss will often differ from men, and the emotional impact can be significant. Female pattern hair loss is common and usually presents as diffuse thinning with preservation of the frontal hairline.
Prevalence and typical presentation
An estimated 30 million women in the U.S. experience female pattern thinning at some point, often accelerating during hormonal transitions like menopause or postpartum. Because thinning is diffuse, diagnosing underlying causes and tailoring safe treatments for women is essential.
Treatment options tailored to women
Topical minoxidil is an approved and commonly used therapy for female pattern thinning, while systemic anti-androgens may be used cautiously when indicated. Regenerative treatments, including stem cell growth factor therapy, offer minimally invasive alternatives that can be particularly attractive to women seeking natural-looking improvement with lower cost and limited downtime compared with surgery.
When to seek professional help
You should consult a clinician if your hair shedding is sudden, patchy, severe, or accompanied by scalp pain, redness, or scarring. Early evaluation increases the chance of identifying reversible causes and preventing permanent follicular damage.
Red flags that warrant urgent attention
Rapid, widespread shedding, signs of infection, scarring changes, or systemic symptoms like weight loss or fatigue should prompt timely assessment. Early intervention can alter long-term outcomes, especially in autoimmune and scarring disorders.
Preventing future hair loss
You can reduce the risk of further root-level hair loss by addressing modifiable factors and adopting hair-friendly practices. Preventive measures include nutritional optimization, gentler styling, and avoidance of unnecessary chemical treatments.
Lifestyle and nutritional considerations
Ensure adequate protein, iron, vitamin D, and biotin when appropriate, and manage stress with sleep, exercise, and relaxation techniques. While supplements can help when you are deficient, excess supplementation without medical indication is rarely beneficial.
Hair care and styling practices
Avoid tight hairstyles, reduce heat and harsh chemical exposures, and use gentle handling when wet to minimize traction and breakage. Protective, low-tension styles and periodic hair rests can preserve follicle integrity.
Practical at-home care while waiting for regrowth
While receiving professional care, you can support regrowth with consistent, gentle routines and approved topical treatments. Expect gradual improvement and adhere to prescribed therapies for months before judging effectiveness.
Daily care tips
Use sulfate-free shampoos, avoid harsh brush strokes, and apply topical agents according to instructions. Track your progress with photos every 4–8 weeks to objectively measure improvements.
Monitoring and when to re-evaluate
If you do not see any improvement after the expected timeframe for your diagnosis, return to your clinician for reassessment or additional testing. Treatment plans often need adjustment or combination approaches for optimal results.
Common myths and misconceptions
You will encounter many myths about hair loss; distinguishing fact from fiction helps set realistic expectations. Understanding the mechanisms of root-level loss prevents unnecessary or harmful interventions.
“Once a hair falls out from the root it’s gone forever”
This is not universally true — many hairs that come out from the root are telogen hairs with intact follicles and can regrow. Only when the follicle is permanently destroyed, as in scarring conditions, is regrowth unlikely without surgery.
“You can regrow hair overnight with topical concoctions”
There are no scientifically proven overnight cures; most effective therapies produce gradual improvement over months. Be skeptical of products or protocols that promise instant or miraculous recovery.
Frequently asked questions (FAQs)
Will hair always regrow after chemotherapy?
Most people experience regrowth after chemotherapy once the drug exposure ends, though timing varies with the regimen. Hair often returns within weeks to months, sometimes with transient texture or color changes.
How soon after stopping the trigger will you see new hair?
For telogen effluvium, you usually see visible improvement within 3–6 months as follicles re-enter anagen. For other conditions, timelines vary, and targeted therapies may accelerate regrowth.
Can scarring alopecia be reversed?
Established scarring that has replaced follicles with fibrous tissue is not reversible by medical therapy. Early detection and immunosuppressive treatment can halt progression and preserve remaining follicles; surgical restoration is an option for cosmetic improvement.
Are stem cell growth factor therapies safe?
Most regenerative growth factor therapies are minimally invasive and well tolerated when performed by trained providers. You should discuss the evidence, expected outcomes, and costs with your clinician, and ensure treatments are performed in accredited settings.
Do natural remedies like oils or massages help?
Scalp massage and certain oils may improve scalp health and comfort, and massage might modestly increase blood flow, but these measures alone rarely reverse significant follicular loss. Use them as adjuncts to evidence-based therapies rather than primary treatments.
Can medications make hair fall out from the roots?
Yes, certain medications (chemotherapy, retinoids, some anticoagulants, and more) can cause root-level shedding. Reviewing your medication list with your clinician is important to identify potential contributors.
Treatment decision framework: how to choose your approach
Selecting a treatment requires balancing diagnosis, expected prognosis, risks, costs, and lifestyle preferences. A stepwise approach starting with reversible causes, progressing to medical therapy, and considering regenerative or surgical options yields the best outcomes.
When to prefer medical therapy
If follicles are intact and you have non-scarring loss or patterned thinning, start with medical therapy (topical or systemic) and consider regenerative adjuncts. Medical therapy is often less invasive and can be effective long term with maintenance.
When to consider regenerative or surgical options
If you have insufficient response to medical therapy, donor follicles available, or localized areas of permanent loss, regenerative injections or transplantation are reasonable next steps. Discuss realistic outcomes, recovery expectations, and costs with your provider.
Summary and key takeaways
Hair that falls out from the root can regrow in many circumstances, especially when the follicle remains intact and the underlying cause is treated. Your prognosis depends on the diagnosis — non-scarring causes usually recover, while scarring causes may require surgical restoration.
You should seek timely evaluation for sudden, extensive, or patchy hair loss to maximize the chance of regrowth. Work with a qualified clinician to diagnose the cause, pursue evidence-based treatments, and consider regenerative therapies as part of a personalized plan to restore your hair and confidence.
