Understand Your Hair Fall
Before Choosing a Treatment

Female pattern hair loss (androgenetic alopecia) is one of the most common causes of hair thinning in women, typically showing as a widening part or crown density loss. In India, telogen effluvium from stress, illness, nutritional deficiency, PCOS or postpartum changes is also very prevalent. Other common causes include thyroid imbalance, iron deficiency and menopause. A dermatologist evaluation helps identify the correct cause. Results vary.

A gradually widening middle partition may indicate female pattern hair loss (FPHL), which is among the most common causes in women. It can also be related to diffuse thinning from nutritional deficiencies, PCOS, hormonal shifts, menopause or telogen effluvium. A dermatologist evaluation — and sometimes blood tests — helps distinguish between these causes. Early identification may help slow progression. Results vary.

Crown thinning in women is often associated with female pattern hair loss, PCOS, menopause or diffuse telogen effluvium. Unlike in men, the frontal hairline is typically preserved. Contributing factors may include androgen sensitivity, low iron, thyroid imbalance or postpartum hormonal changes. A dermatologist evaluation with blood tests helps identify the underlying cause. Results vary.

Temporary hair fall (telogen effluvium) typically follows a trigger — illness, stress, childbirth, rapid weight loss or nutritional deficiency — and usually resolves within 3–6 months. Female pattern hair loss is gradual and progressive without treatment. Patchy hair loss (alopecia areata) can be temporary or recurrent. Scarring alopecia is generally permanent. A dermatologist can assess the pattern and advise appropriately. Results vary.

Yes. PCOS can cause androgenic hair thinning in women due to elevated androgen levels. This typically shows as diffuse thinning or widening part rather than complete baldness, and often alongside acne, oily skin, irregular periods or increased facial hair. A dermatologist and gynaecologist evaluation is recommended. Managing the underlying hormonal imbalance is usually the priority. Results vary.

Yes. Both hypothyroidism and hyperthyroidism can cause diffuse hair shedding by disrupting the hair growth cycle. Thyroid-related hair fall is typically all-over rather than patchy, and often occurs alongside fatigue, weight change or temperature sensitivity. A thyroid blood test (TSH, T3, T4) is recommended before any hair treatment decisions. Managing the thyroid condition usually leads to gradual hair recovery. Results vary.

Yes. Postpartum hair shedding (telogen effluvium after delivery) is a common and normal physiological process. During pregnancy, elevated hormones keep more hair in the growth phase. After delivery, hormones drop and many follicles shift to the shedding phase simultaneously — causing noticeable hair fall typically 2–4 months after childbirth. Recovery usually occurs naturally within 3–6 months. Heavy, patchy or prolonged shedding beyond 12 months should be assessed by a dermatologist.

Postpartum hair shedding typically peaks at 3–4 months after delivery and gradually resolves over the next 3–6 months, with most women recovering by 12 months postpartum. Recovery depends on nutritional status, iron levels, breastfeeding and whether any underlying pattern hair loss was present. If shedding is heavy, prolonged or accompanied by other symptoms, a dermatologist evaluation is recommended. Results vary.

Yes. Declining oestrogen during perimenopause and menopause can accelerate hair thinning — particularly female pattern hair loss. The pattern typically shows as widening part and crown density reduction, with the frontal hairline usually preserved. A dermatologist evaluation helps assess contributing factors. Treatment options depend on overall health, symptoms and suitability. Results vary.

Low iron or low ferritin (stored iron) is associated with diffuse hair shedding in women, particularly those with heavy periods, vegetarian diets or poor nutritional absorption. A blood test (serum ferritin, CBC) is recommended before supplementing — iron supplementation without confirmed deficiency carries risks. A dermatologist or physician evaluation is recommended. Results vary.

Hair shedding refers to losing more whole hair strands than normal — 50–100 per day is average, but shedding spikes after stress or illness. Hair thinning refers to each strand becoming finer over time as follicles miniaturise, reducing overall density. Both can occur together. Identifying which is happening helps direct the right guides and most appropriate care approach.

Minoxidil is approved for female pattern hair loss in appropriate candidates. The 2% formulation is most commonly used for women. It is not appropriate during pregnancy or breastfeeding. Some women experience initial shedding in the early weeks. Scalp irritation and rarely unwanted facial hair growth can occur. Consistent daily application is required. Dermatologist evaluation is recommended before starting to confirm suitability, concentration and method. Results vary.

Supplements may support hair health when a specific nutritional deficiency is confirmed (iron, Vitamin D, protein, zinc). General supplements with biotin, amla or collagen have limited evidence for hair loss specifically. They are not a substitute for medical treatment of PCOS, thyroid or pattern hair loss. Blood tests to confirm deficiency before supplementing are advisable. Excess supplementation carries risks. Results vary.

Dandruff itself does not directly cause permanent hair loss, but significant scalp inflammation from seborrheic dermatitis can affect the scalp environment, and excessive scratching can cause mechanical damage. Managing the scalp condition typically reduces associated shedding. Actives like ketoconazole and zinc pyrithione are commonly used. Doctor evaluation is recommended for persistent or severe scalp conditions.

See a dermatologist if you notice sudden or rapid hair loss, patchy bald spots, scalp pain or crusting, scarring patches, hair loss with irregular periods or acne, thyroid symptoms, heavy periods with suspected anaemia, hair fall during pregnancy or breastfeeding, hair fall after a new medication, child or teenage hair loss, or no improvement after 3–6 months of appropriate routine care. Early evaluation leads to better outcomes.

No. The AI Hair Test is an educational screening and directional tool — not a medical diagnosis. It helps identify possible patterns, understand concern types and prepare relevant questions for a dermatologist. It does not replace clinical examination, trichoscopy or blood tests. For medically complex, sudden, severe or patchy hair loss — or during pregnancy or breastfeeding — a qualified dermatologist assessment is essential.

Start with the guide that most closely matches your primary symptom. For a widening part or crown thinning, start with Female Pattern Hair Loss. For sudden diffuse shedding, read Telogen Effluvium. For PCOS, try PCOS Hair Loss. After delivery, start with Postpartum Hair Loss. Or use the Pathway Finder above.
