Hair Fall in Men and Women: Causes, Stages and When to See a Dermatologist
Hair fall can reflect pattern loss, illness, stress, deficiencies, thyroid or hormonal changes, or scalp conditions. Losing 50 to 100 hairs daily is usually normal, but persistent shedding, patches or visible thinning deserve attention. A dermatologist can identify causes and discuss options. Hair in your brush or shower can be unsettling. It is natural to wonder whether the change is temporary or likely to continue. This guide covers causes, stages, evaluation and options. For surgical restoration, read about hair transplant treatment.

What Is Normal Hair Shedding?
Losing 50 to 100 hairs a day is common; many people have around 100,000 scalp hairs. Washing affects what you notice, so one day’s count is not diagnostic.
Hair grows in a repeating cycle:
- Anagen: The active growth phase, which lasts for years on the scalp.
- Catagen: A short transition phase when growth slows and the follicle changes.
- Telogen: A resting phase lasting several weeks to months.
- Exogen: The release or shedding of a hair, making room for a new one.
Most scalp hairs are growing at any time. Shedding is the release of hairs; hair loss is reduced density or a changed hairline. They may occur together.

Common Causes of Hair Fall
Pattern and timing help distinguish temporary shedding, progressive loss and scalp or health conditions.
Androgenetic alopecia
Androgenetic alopecia is inherited pattern hair loss and the most common cause in both sexes. Follicles gradually shrink, often influenced by sensitivity to androgens such as DHT.
What it looks like:
- In men: Receding temples and thinning at the crown, which may gradually join.
- In women: A wider central part and diffuse thinning over the top of the scalp, often with the frontal hairline preserved.
What a dermatologist looks for:
- Pattern and family history: Distribution of thinning and similar changes in relatives.
- Follicle miniaturisation: Shaft thickness variation, sometimes clearer with trichoscopy.
Telogen effluvium
Telogen effluvium causes increased shedding, commonly two to three months after fever, surgery, childbirth, crash dieting or major stress. It often settles within about six months once the trigger resolves.
What it looks like:
- Diffuse shedding: More loose hairs across the scalp rather than one sharply defined bald patch.
- Delayed timing: Shedding may begin after the stressful event or illness has passed.
What a dermatologist looks for:
- Recent events: Illness, surgery, childbirth, weight change, dietary restriction, medicine or stress.
- Other explanations: Pattern loss, scalp disease or a health issue.
Nutritional deficiencies and thyroid disease
Iron or ferritin deficiency, low vitamin D or B12, and thyroid disease may contribute to hair changes. Hair loss alone cannot identify the cause.
What it looks like:
- Diffuse change: Shedding or reduced density without a classic pattern.
- Additional symptoms: Fatigue, temperature intolerance or weight changes may coexist but are not specific.
Dermatologist checks: Diet, blood loss, medicines, health conditions and symptoms; targeted blood tests may be considered from the history and examination.
Hormonal causes in women
Polycystic ovary syndrome (PCOS), childbirth and menopause can coincide with changes in shedding or density. Hormonal changes may trigger temporary shedding or reveal underlying pattern loss.
What it looks like:
- Part widening or diffuse shedding: Often most noticeable on the top.
- Other hormonal signs: Irregular periods, acne or increased facial hair may be relevant.
Dermatologist checks: Menstrual, postpartum and menopausal history; a hormone profile may be considered when indicated.
Alopecia areata
Alopecia areata is an autoimmune condition that often causes smooth, round or oval patches. It can affect the scalp, beard or eyebrows, and its course varies.
What it looks like:
- Distinct patches: Sudden areas of missing hair, usually without scale or scarring.
- Nail changes: Small pits may occur.
What a dermatologist looks for:
- Patch pattern: Examination of the scalp and other affected areas, including nails.
- Signs of activity: Broken or short hairs may show at the patch edge.
Scalp conditions
Dandruff, seborrheic dermatitis and fungal infection can cause scale, itching or inflammation. A scaly scalp does not automatically mean fungal infection, so examination matters.
What it looks like:
- Flaking or itch: Greasy or dry scale and redness may be present.
- Possible infection: Some fungal infections cause broken hairs or patches.
What a dermatologist looks for:
- Scalp exam: Scale, redness, tenderness and broken hairs; sampling may help distinguish fungal infection from dermatitis. Learn about seborrheic dermatitis care.
Medications, traction and hairstyling
Some medicines can contribute to shedding, while repeated tension from tight hairstyles can cause traction alopecia. Heat and chemical treatments may break hair shafts.
What it looks like:
- Hairline or edge thinning: Tight braids, buns or extensions may stress the same areas.
- Breakage: Short, uneven strands may indicate shaft damage.
Dermatologist checks: Hairstyling, treatments, supplements and medicines, plus distribution, inflammation and breakage.
Hair Fall Stages: Norwood Scale (Men) and Ludwig Scale (Women)
The Norwood (1975) and Ludwig (1977) scales describe androgenetic alopecia patterns; they do not diagnose every cause.
| Norwood stage | Typical pattern in men |
|---|---|
| I | Little or no recession at the temples |
| II | Mild temple recession, sometimes called a mature hairline |
| III | More pronounced temple recession; crown thinning may also begin (III vertex) |
| IV | Deeper recession and a more distinct crown area, with a band of hair between them |
| V | The thinning areas enlarge and the separating band narrows |
| VI | The temple and crown areas join; hair remains mainly at the sides and back |
| VII | Most advanced pattern, with a narrower horseshoe-shaped fringe remaining |
| Ludwig stage | Typical pattern in women |
|---|---|
| I | Mild thinning over the crown; part may widen |
| II | More noticeable density reduction over the top |
| III | Extensive thinning over the crown and top of the scalp |
In female pattern hair loss, the frontal hairline is often preserved as the central part widens.
Hair Fall Stages: Quick Reference
Next steps depend on pattern and likely cause.
| Stage or pattern | What you see | Typical next step |
|---|---|---|
| Early pattern change | Mild temple recession or a wider part | Confirm the pattern and discuss monitoring or medical therapy evaluation |
| Moderate pattern thinning | Crown or top-of-scalp density reduction | Scalp examination, cause assessment and discussion of appropriate options |
| Advanced pattern loss | Larger joined areas or extensive crown thinning | Review goals, donor hair and suitability for medical or procedural options |
| Sudden diffuse shedding | Increased loose hairs across the scalp | Review triggers and health history; assess for telogen effluvium or other causes |
| Patchy or inflamed loss | Bare patches, scale, pain or redness | Prompt dermatology assessment to identify the specific condition |
A Simple Self-Check at Home
Home observations cannot confirm a cause, but can help describe a change.
- Gentle pull test: More than about 10% of gently pulled hairs coming out is generally positive; technique and recent washing affect results.
- Part and temples: Track part width and hairline changes over time.
- Monthly photographs: Take front, top and crown photos in the same light and position.
Temporary vs Permanent Hair Fall
Temporary shedding often follows a trigger; pattern loss usually develops gradually. Both can occur together.
| Feature | Temporary shedding, such as telogen effluvium | Progressive pattern hair loss |
|---|---|---|
| Onset | Often begins weeks to months after a trigger | Usually gradual over months or years |
| Distribution | Commonly diffuse across the scalp | Often follows a recognisable pattern |
| Course | May ease as the trigger resolves | Can continue without assessment and management |
| Evaluation | Trigger history | Pattern and follicle miniaturisation |
What a Dermatologist Checks
A dermatologist combines history and scalp examination; testing depends on findings.
- History: Timing, pattern, illness, surgery, childbirth, stress, diet, medicines and family history.
- Scalp examination: Density, hairline, inflammation, scale, scars and breakage.
- Trichoscopy and pull test: Magnification shows shaft and follicle features; a pull test checks shedding.
- Commonly considered blood tests: CBC, ferritin, TSH, vitamin D and B12 may be ordered when clinically relevant.
- Women’s hormone assessment: A hormone profile may be considered when symptoms or history suggest PCOS or another hormonal cause.
Hair Fall Treatment in Nagpur: Options by Stage
Radiance Clinic’s hair services include medical, injectable and surgical options; a dermatologist chooses among them according to the cause, stage and your health history, and results vary.
| Finding or stage | Options the dermatologist may evaluate |
|---|---|
| Early or moderate pattern loss | Medical therapy, including whether minoxidil or finasteride is appropriate (finasteride is generally used in men and is avoided in pregnancy or when planning pregnancy; women’s medical options are assessed separately); alopecia treatment |
| Pattern loss where an adjunct procedure is being considered | PRP therapy, GFC therapy, follicular stem cell therapy, exosome hair therapy, hair booster injections or mesotherapy |
| Advanced, stable pattern loss in a suitable candidate | Hair transplant; female hair transplant may be assessed for selected women |
Treatment differs by cause. Telogen effluvium care addresses its trigger, alopecia areata and scalp infections need targeted treatment, and scarring hair loss needs prompt specialist care.
Evidence also varies between options. PRP has more published trial data than GFC, exosome and stem-cell-based approaches, but a 2024 meta-analysis of randomized trials found high heterogeneity and called for better trials (Kieling et al., 2024). Ask your dermatologist what is and isn’t established.

When to See a Dermatologist
Arrange an assessment in Nagpur or elsewhere for sudden, persistent, patchy or painful loss, or hair loss with other health changes.
- Sudden patchy loss: New smooth patches or rapid loss in one area.
- Burning, pain or scarring: Tenderness, sores, shiny skin or loss of visible follicle openings needs timely attention.
- Prolonged shedding: Shedding that continues beyond about three months, especially without a clear improving trend.
- Early onset: Hair loss beginning in the late teens or early 20s.
- Associated symptoms: Thinning with fatigue, weight change or irregular periods.
Common Hair Fall Myths
Everyday habits such as oiling, shampooing or helmet use rarely explain persistent hair loss; tight hairstyles and chemical or heat damage are the exceptions covered above.
- Oiling: It can condition hair but does not reverse follicle miniaturisation or correct internal causes.
- Frequent shampooing: Washing releases hairs already in the shedding phase; shampooing itself does not usually cause follicle loss.
- Helmets: Normal use does not cause pattern baldness; poor fit or friction may irritate skin or break hair.
Frequently Asked Questions
Q: How many hairs fall per day is normal?
A: About 50 to 100 hairs a day is common, though the amount varies and may look greater on wash days. A persistent change in density or pattern matters more than counting every strand.
Q: Is hair fall in monsoon normal?
A: Many people notice more shedding in some seasons, and humid weather can worsen dandruff and scalp infections that add to hair fall. Shedding that is heavy, patchy or lasts beyond about three months is not explained by weather alone and is worth a dermatologist’s assessment.
Q: Can hair regrow naturally?
A: Hair may recover after temporary shedding once the trigger resolves, but regrowth depends on the cause and whether follicles remain active. Pattern hair loss may continue without suitable assessment and management.
Q: Which doctor should I see for hair fall?
A: A dermatologist, a doctor trained in conditions of the skin, hair and scalp, is the usual first choice, because hair fall can come from skin, hormonal, nutritional or other health causes. They may order tests or involve other specialists, such as an endocrinologist or gynaecologist, when the history points that way.
Q: Can stress cause permanent hair loss?
A: Major stress can trigger telogen effluvium, which is often temporary and may settle as the trigger resolves. Stress can also coincide with or reveal pattern loss, so persistent shedding deserves an assessment.
