Seeing more hair on your pillow, in the shower drain or on your comb can be frightening. The good news is that most hair fall has an identifiable cause, and many causes are treatable, especially when you act early. This guide explains what is normal, what is not, and which treatments dermatologists use.

Normal shedding vs excess hair fall

Most people lose about 50 to 100 hairs a day as part of the natural hair cycle. You may be losing too much if you notice a visibly thinner ponytail, a widening parting, a receding hairline, bald patches, or clumps of hair coming out when you wash or comb.

Common causes of hair fall

• Stress or illness: A major event, fever, surgery or crash dieting can push many hairs into the shedding phase two to three months later (called telogen effluvium).
• Nutritional gaps: Low iron, vitamin D, vitamin B12 or protein are common contributors.
• Hormonal and thyroid issues: Thyroid disorders, PCOS and postpartum changes often affect hair.
• Genetics: Pattern hair loss (androgenetic alopecia) affects both men and women, with thinning on the crown or a receding hairline.
• Scalp problems: Dandruff, seborrheic dermatitis and fungal infections can weaken hair.
• Hair practices: Tight hairstyles, frequent heat styling, bleaching and harsh chemical treatments.

Hair fall in women

Women usually notice diffuse thinning, a wider parting or a smaller ponytail rather than bald patches. Common triggers include iron deficiency, thyroid problems, PCOS, postpartum changes and crash diets. Because several causes can overlap, blood tests and a hormonal history are especially useful.

Hair fall in men

In men, the most common pattern is a receding hairline and thinning at the crown, usually linked to genetics and hormones. It tends to progress slowly, so starting treatment early gives the best chance of keeping the hair you have.

When to see a doctor

Do not wait if hair fall is sudden, patchy or painful, or comes with scalp burning, scaling or redness. See a doctor if it has continued for more than two to three months, or if you have other symptoms such as fatigue, weight change or irregular periods. Early treatment protects the follicles that are still active.

How hair fall is diagnosed

A good evaluation begins with your history, diet, medicines and family background, followed by a scalp examination, often with a magnified scalp scope (trichoscopy). Blood tests such as haemoglobin, ferritin, vitamin D, vitamin B12 and thyroid profile may be advised, along with hormonal tests where indicated. Treating hair fall without finding the cause is the most common reason people do not get results.

Treatments dermatologists use

• Treating the cause: Correcting deficiencies, thyroid disorders or scalp infections.
• Topical treatments: Such as minoxidil, which can help slow hair loss and promote regrowth in pattern hair loss when used consistently.
• Prescription medicines: Selected oral treatments in specific cases, started only after a consultation.
• PRP (platelet-rich plasma): A procedure that uses concentrated platelets from your own blood, injected into the scalp to support follicles. Evidence is encouraging for pattern hair loss, but results vary and several sessions are needed.
• GFC and mesotherapy: Related scalp injection treatments that deliver growth-supporting factors or nutrients.
• Low-level laser therapy: A light-based treatment used as a supportive therapy for thinning hair.
• Hair transplant: An option for advanced, stable baldness when medicines and procedures cannot restore enough density.

How long does treatment take?

Hair grows slowly, about a centimetre a month. Most treatments need three to six months before improvement is noticeable, and some people see a temporary increase in shedding at the start of treatment. Consistency matters more than switching products every few weeks.

Hair fall myths

• Myth: Oiling stops hair fall. Oil can condition hair and reduce breakage, but it does not treat the cause of hair loss.
• Myth: Frequent shampooing causes hair fall. A clean scalp supports healthy hair; the strands you see in the drain were already shedding.
• Myth: Cutting hair makes it grow faster or thicker. Hair grows from the root, and trimming only removes damaged ends.

Foods that support healthy hair

• Protein sources such as eggs, dal, paneer, curd, fish or chicken.
• Iron-rich foods such as leafy greens, ragi, dates and jaggery, with a source of vitamin C to help absorption.
• Nuts and seeds for healthy fats and zinc.
• Fruit and vegetables for vitamins and antioxidants.

Avoid taking random hair supplements without testing. Too much of some nutrients can be harmful, and supplements help only when you are actually deficient.

Everyday habits that help

Eat enough protein and include iron-rich and vitamin-rich foods, manage stress, sleep well, avoid tight hairstyles and limit heat and chemical treatments. Use a gentle shampoo suited to your scalp, and avoid rough towel-drying when hair is wet and fragile.

Frequently asked questions

Does hair fall increase in October?

Some seasonal shedding is common when the weather changes, and humidity, dandruff and stress can add to it. If heavy shedding lasts more than two to three months, get your scalp and blood levels checked.

Is PRP for hair painful?

A numbing cream and very fine needles are used, so most people feel only mild discomfort. Some tenderness on the scalp for a day is possible.

Can hair fall be reversed?

It depends on the cause. Stress- or nutrition-related hair fall is often fully reversible, while pattern hair loss can usually be slowed and improved, particularly when treated early.

Do hair supplements work?

They help only if a deficiency is the cause. Get tested first, then take what your doctor advises. For pattern hair loss, supplements alone are rarely enough.
