Quick answer
Most hair fall is caused by a mix of genetics (pattern hair loss), nutritional deficiencies (iron, vitamin D, protein), hormonal changes (thyroid, PCOS, post-pregnancy), stress, and scalp conditions like dandruff. Losing 50–100 hairs a day is normal. If you notice a widening part, a receding hairline, visible scalp, or clumps of hair, it is worth getting a professional scalp evaluation. Early treatment — from correcting deficiencies to PRP therapy and medical scalp care — gives the best chance of regrowth.
Finding hair on your pillow, in the shower drain, or on your comb is one of the most common concerns we see at Dermacare in Himayat Nagar, Hyderabad. The good news: in the large majority of cases, hair fall is treatable — if you identify the real cause early and act on it. This guide explains why hair falls out, how to tell normal shedding from a problem, and the treatments that actually work.
The average adult scalp has around 100,000 hairs, and it is completely normal to shed 50 to 100 hairs a day. Each hair follicle cycles through growth (anagen), transition (catagen), and rest (telogen) phases, then sheds and regrows. You only start to see thinning when more follicles enter the resting/shedding phase than are regrowing, or when follicles shrink over time.
Signs that your hair fall may need attention:
Androgenetic alopecia — male- and female-pattern hair loss — is the single most common cause. It is driven by genetics and the hormone DHT, which gradually shrinks follicles. In men it shows as a receding hairline and crown thinning; in women as diffuse thinning over the top of the scalp. It is progressive, so earlier treatment protects more hair.
Low iron (ferritin), vitamin D, vitamin B12, and inadequate protein are frequent contributors, especially in vegetarian diets and among women with heavy periods. Crash diets and sudden weight loss are common triggers.
Thyroid disorders (both under- and over-active), PCOS, pregnancy and post-delivery changes, and menopause all affect the hair cycle. Post-pregnancy shedding (telogen effluvium) is very common around 2–4 months after delivery and usually recovers.
A major physical or emotional stressor — surgery, high fever, COVID-19, severe stress — can push many follicles into the resting phase at once, causing noticeable shedding 6–12 weeks later. This type usually recovers once the trigger passes.
Dandruff, seborrheic dermatitis, fungal infection, and an inflamed or oily scalp weaken the follicle environment and worsen shedding. Treating the scalp is often the missing piece. See our guide to dandruff and flaky scalp.
Tight ponytails and buns (traction alopecia), frequent heat styling, and harsh chemical treatments cause breakage and, over time, follicle damage — especially along the hairline.
Certain medicines (some for blood pressure, depression, acne, and others), uncontrolled diabetes, and autoimmune conditions such as alopecia areata can all cause hair loss.
Hair naturally becomes finer and grows more slowly with age, and hormonal shifts around menopause accelerate thinning for many women.
A proper diagnosis matters because the treatment for a vitamin deficiency is completely different from the treatment for pattern hair loss. At a hair & scalp consultation you can expect:
| Treatment | Best for | What to expect |
|---|---|---|
| Correcting deficiencies & diet | Nutritional / post-illness shedding | Improvement over 3–6 months once levels are restored |
| Medical therapy (topical/oral, doctor-prescribed) | Pattern hair loss | Slows loss and can regrow hair; needs consistency |
| PRP therapy | Early–moderate thinning, weak follicles | Course of sessions; strengthens and thickens hair |
| Scalp / trichology treatments | Dandruff, oily or inflamed scalp | Healthier scalp = less shedding |
| Nutrition & lifestyle support | Everyone | Foundation for any treatment to work |
Most people do best with a combination approach — fix the underlying cause, support the scalp, and strengthen the follicles. Results take time: hair grows about 1 cm a month, so give any treatment at least 3–6 months before judging it.

If you shed more than about 100 hairs a day for several weeks, see a widening part, receding hairline, visible scalp, bald patches, or scalp itching and flaking, it is worth getting a professional scalp evaluation. Early assessment gives the best treatment results.
Often, yes — especially when it is caused by deficiencies, stress, post-pregnancy changes, or scalp conditions, which are usually reversible once treated. Genetic (pattern) hair loss can be slowed and partly regrown but needs ongoing treatment because it is progressive.
Iron (low ferritin) and vitamin D deficiency are the most common in our patients, along with vitamin B12 and inadequate protein. A simple blood test can confirm which ones apply to you.
Yes. Significant physical or emotional stress can push many follicles into the shedding phase, causing noticeable hair fall 6–12 weeks later (telogen effluvium). It usually recovers once the stressor is resolved.
Because hair grows roughly 1 cm per month, most treatments need 3–6 months of consistent use before you see a clear difference. Reduced shedding is usually the first sign, followed by new growth and thickness.
It varies by cause and treatment — correcting a deficiency is inexpensive, while treatments like PRP are charged per session. At Dermacare we start with a diagnosis so you only pay for what you actually need. Contact us for current pricing.
