- Pattern tells you the category; blood work confirms the correctable part.
- Early treatment protects existing follicles — nothing regrows a scarred one.
- Nutrition and hormones must be addressed alongside any procedure.
Read the pattern first
Diffuse shedding from all over, especially with a recent illness, delivery, surgery or rapid weight loss, points to telogen effluvium — usually self-limiting once the trigger resolves. Progressive thinning at the temples, crown or a widening midline part points to androgenetic pattern loss, which is chronic and needs sustained treatment. Discrete smooth patches need medical assessment, not a salon treatment.
Gradual thinning at the temples, crown or midline part. Responds best to early, sustained treatment.
Diffuse shedding that follows a hormonal event by two to three months.
Very common in Indian diets, especially in menstruating women and vegetarians.
Itch, flaking or tenderness alongside shedding. Treat the scalp before chasing regrowth.
Telogen effluvium after illness, surgery or rapid weight loss. Usually reversible.
The tests worth doing before spending anything
- Complete blood count and ferritin — low stored iron is the most frequently missed cause in women
- Thyroid profile (TSH, and free T4 where indicated)
- Vitamin D and B12 — widely low in Indian adults, especially vegetarians
- Blood sugar and, where cycles are irregular, a PCOS-directed hormonal panel
- Recent blood reports — thyroid, ferritin, vitamin D, B12, HbA1c if available
- Photos of your skin or scalp on a bad week, in daylight
- Every product you currently use, including home remedies
- Prescription and over-the-counter medication list
- What you have already tried, and what made things worse
- Your realistic budget and how much downtime you can take
Treatment routes, honestly compared
Daily topical therapy is the foundation for pattern loss and only holds while it continues. PRP adds concentrated growth factors and can accelerate response in early to moderate thinning across three to four monthly sessions. Nutritional correction addresses the reversible portion and is often the cheapest meaningful intervention. Where the scalp is smooth and shiny with no visible follicles, none of these will regrow hair — that is a transplant conversation.
- Session 1Baseline
Photos, scalp assessment and blood work review. Mild tenderness for a day.
- Month 1–3Monthly sessions
Three to four sessions spaced four weeks apart. Shedding may briefly increase.
- Month 3First review
Compare standardised photos. Reduced shedding usually precedes visible density.
- Month 4–6Density change
Finer hairs thicken. Nutrition and any hormonal driver must be addressed in parallel.
- Month 6+Maintenance
Top-ups every three to six months if the response justifies continuing.
What a fair timeline looks like
Expect reduced shedding at eight to twelve weeks, finer regrowth at three to four months, and thickening of that regrowth by six. Standardised photographs — same light, same parting, same angle — are the only reliable measure. Memory is a poor instrument here in both directions.
- Adequate protein daily — most Indian diets fall short
- Correct iron and vitamin D on evidence, not guesswork
- Avoid tight ponytails, braids and repeated chemical straightening
- Wash frequently enough to keep the scalp clean in humidity
Myths vs facts
Frequently asked questions
Should I do PRP or fix nutrition first?+
Both, in parallel. PRP without correcting low ferritin or an untreated thyroid usually underperforms.
Is hair fall after COVID or dengue permanent?+
Almost never. Post-illness telogen effluvium typically recovers over six to nine months with adequate nutrition.
Can stress alone cause hair fall?+
Sustained stress can trigger telogen effluvium, and it commonly accelerates an underlying pattern loss that was already present.
Do onion juice and home oils regrow hair?+
They may reduce breakage and improve scalp comfort. They do not reverse androgenetic thinning or replace treating a deficiency.
Key takeaways
- Pattern plus blood work identifies the cause in most cases
- Treat early — protecting follicles is easier than regrowing them
- Photograph monthly under identical conditions
- No treatment regrows hair from scarred, follicle-free scalp
