DHT & follicle miniaturisation
In susceptible follicles, 5-alpha-reductase turns testosterone into DHT, which shrinks the follicle cycle after cycle until thick hairs are replaced by fine, pale ones.
Part One · The clinic
Sanskrit: khalitya — hair fall · palitya — premature greying
A long-form guide that reads hair loss and greying through two lenses — modern dermatology (DHT, follicle miniaturisation, melanocyte stem-cell loss, minoxidil and finasteride) and the classical Indian tradition (khalitya, palitya, nasya, bhringraj, amla) — ending in a practical eat / apply / live plan.
The clinic’s terms and the classical ones, read side by side — not one against the other.
How pattern hair loss actually works — 5-alpha-reductase, DHT and the follicle that miniaturises cycle after cycle — and what the evidence supports, from minoxidil and finasteride to the honest caveats about what they can and cannot do.
Grey is colour the hair stops making: melanocyte stem-cell loss, oxidative stress and the catalase that fades with age. The guide is clear about what is reversible, what is not, and where stress and deficiency fit in.
The same two conditions read as khalitya and palitya — Pitta and heat, nasya, bhringraj and amla — alongside the Puranas and epics, where the first grey hair is a messenger rather than a defect to hide.
It ends where it is useful: what to put on your plate, what to put on your scalp, and the daily habits both traditions point to — framed as maintenance and prevention, with a nudge to get bloodwork when loss is sudden or early.
