Hair Loss: Causes & Treatment
Dermatologist-led overview of how hair loss is evaluated and the evidence behind common treatments.
View AAD reference ›If you notice more hair in the comb at the same time each year — often through the monsoon and into autumn — you're not imagining it. The hair cycle naturally varies through the year, and humidity, sweat, sun and scalp conditions can add to it. Mild seasonal shedding is usually temporary and settles in weeks to a couple of months. But it would be wrong to assume seasonal shedding never needs treatment: heavier or lasting loss can have another cause. Hairsncares helps you tell mild-and-seasonal from something worth checking.
Illustrative sample only. AI screening helps guide decisions and does not replace a dermatologist's diagnosis.
A mild, temporary rise in shedding at a particular time of year is common — the hair cycle naturally varies, and in India shedding often increases during and after the monsoon, helped along by humidity, sweat and scalp issues like dandruff. This kind of shedding is usually self-limiting and settles within weeks to a couple of months, so supportive scalp care and patience are often all that's needed. But "seasonal" doesn't mean "ignore it": if shedding is heavy, lasts longer than a couple of months, recurs strongly, or comes with bald patches or scalp symptoms, it may not be simply seasonal and deserves a dermatologist's check. Use the AI guide to compare your pattern, then support your hair — or get assessed if it doesn't fit.
Seasonal shedding is often mild and temporary, but heavy, persistent or patchy loss needs review.
AI Summary
Seasonal hair fall is one possible hair-loss pattern or trigger. The right next step depends on whether hair is shedding from the root, breaking from the shaft, thinning in a pattern, falling suddenly, persisting for months or appearing in patches.
This page is educational and screening-oriented. It does not diagnose, prescribe or guarantee results. Use the AI Hair Test to organise symptoms, and consult a dermatologist if symptoms are severe, persistent, patchy, painful or progressive.
Best next step: identify the pattern, check likely triggers, review red flags, then choose a routine, product pathway or doctor consultation safely.
Seasonal hair fall is a mild, temporary increase in shedding that tends to happen at a certain time of year. Many people notice it in late summer to autumn, and in India often during and after the monsoon. It's thought to reflect natural variation in the hair growth cycle, along with seasonal factors like humidity, sweat, sun exposure and scalp conditions.
The reassuring part is that seasonal shedding is usually self-limiting — it settles within weeks to a couple of months as the season changes, and overall density stays broadly stable across the year. The follicles are healthy; this is a phase, not permanent loss.
That said, "seasonal" should never be a reason to ignore hair fall. If shedding is heavy rather than mild, lasts longer than a couple of months, keeps worsening, or comes with bald patches or scalp symptoms, it may not be purely seasonal — and that deserves a dermatologist's check. The skill is telling mild-and-seasonal from something more.
| Aspect | What it means |
|---|---|
| Distribution | Diffuse, all over |
| Timing | Same season each year |
| Severity | Mild increase — not dramatic |
| Duration | Weeks to ~2 months, then settles |
| Follicle damage? | Usually none — density recovers |
| First step | Scalp care + patience; assess if heavy |

These products offer supportive scalp and hair care to see your hair through a seasonal shedding phase. They do not treat medical causes of hair loss such as deficiency, thyroid problems or pattern loss, and no product or supplement is guaranteed to regrow hair. Supplements help mainly where a deficiency is confirmed by testing. If shedding is heavy, lasts beyond a couple of months, recurs strongly, or comes with scalp problems or other symptoms, see a dermatologist rather than relying on products. Prices, ratings and availability are placeholders to be populated dynamically. Results vary.

Use the GuideAll Ingredients"Lots of patients tell me their hair sheds more in the monsoon or autumn, and for most of them it's mild, it settles, and they don't need much beyond good scalp care and patience. I'm happy to reassure them. What I won't do is wave away every complaint as 'just seasonal'. If the shedding is heavy, drags on past a couple of months, comes back harder each year, or the scalp is angry and itchy, that's not simply the season — that's worth examining. Treat mild seasonal shedding kindly; get the rest checked."

Hair loss treatment should start by identifying the pattern. Pattern thinning, diffuse shedding, patchy loss, sudden shedding and hair breakage need different next steps.
May suggest androgenetic alopecia or DHT-related pattern hair loss. Often gradual and progressive.
Androgenetic Alopecia →May relate to telogen effluvium, deficiency, thyroid, illness, stress, postpartum phase or diffuse pattern loss.
Diffuse Hair Thinning →Often follows a trigger weeks to months earlier, but sudden shedding should not be dismissed if severe or persistent.
Sudden Hair Fall →Persistent shedding needs cause-finding: chronic TE, thyroid, deficiency, medicines, hormones or pattern loss.
Chronic Hair Fall →Patchy loss may be alopecia areata, fungal infection or scarring alopecia and should be dermatologist-led.
Patchy Hair Loss →Breakage is shaft damage, not root shedding. It needs damage repair and styling changes, not root-hair-fall treatment.
Breakage vs Hair Fall →Cause Map

Read Guide →Diffuse shedding after triggers such as fever, COVID, stress, childbirth, surgery, dieting or deficiency.
Read Guide →Iron, vitamin D, thyroid and nutritional issues can contribute to diffuse shedding and chronic hair fall.
Supplement Safety →Round bald patches need dermatologist diagnosis because causes and treatments differ greatly.
Patchy Hair Loss →Stress, rapid weight loss, illness, smoking and alcohol may contribute, but rarely act alone.
Stress Hair Loss →Breakage from heat, chemicals, friction or styling is different from root hair fall.

Short-term shedding after a known trigger can be tracked with photos, routine consistency and symptom notes.
Use the AI Hair Test to organise pattern, duration, triggers, scalp symptoms and next-step direction.
Hair fall lasting more than 6 months, worsening crown thinning, a widening parting or unclear shedding needs evaluation.
Patchy loss, scalp pain, pus, crusting, bleeding, scarring-looking skin, sudden severe shedding or child scalp scaling needs prompt medical review.
Timeline
Fever, COVID, stress, surgery, childbirth, crash dieting or major illness may push hairs into the shedding phase.
Shedding may become noticeable after a delay, often once the original trigger already feels over.
Supportive care, trigger correction, nutrition and scalp comfort help recovery, but timelines vary.
Heavy, persistent, patchy or progressive loss should be checked rather than assumed harmless.
Assessment
Low ferritin can contribute to diffuse shedding. Iron should be taken only after testing and doctor advice.
Thyroid imbalance can cause diffuse shedding and needs medical management, not hair products alone.
Vitamin D, protein intake and nutritional history may matter, especially after dieting or illness.
Dermoscopy or scalp examination helps separate pattern loss, shedding, inflammation, fungal causes and scarring risks.
When It's Not Just Seasonal
Many people notice a mild, temporary increase in shedding at certain times of year, which often settles on its own. But heavy, persistent or patchy loss, or shedding with scalp symptoms, should not be brushed off as 'just seasonal' and deserves screening and, if needed, a doctor.

The monsoon is when many people in India notice the most shedding. Humidity, sweat and damp hair create conditions where dandruff and scalp irritation flare more easily, and scratching an itchy scalp adds to hair fall. Seasonal cycle variation can sit on top of this.
The most useful response is good scalp hygiene: wash regularly with a gentle or anti-dandruff shampoo as needed, avoid leaving hair damp for long, dry the scalp properly, and keep combs and towels clean. Eat well, handle hair gently, and don't panic-switch products. If the scalp becomes very itchy, flaky, red or sore, or shedding is heavy, that points beyond simple seasonal shedding — a dermatologist can check for scalp conditions that need specific treatment.
