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.

Kesha: a hair fall & premature greying guide
Why hair thins and greys, and what actually works.
Sanskrit: khalitya — hair fall · palitya — premature greying
Learn what is really behind your hair fall or early greys, which treatments have evidence behind them, and leave with a personal plan, the blood tests to ask about and a weekly routine you can track. Read through two lenses: modern dermatology (DHT, follicle miniaturisation, minoxidil and finasteride) and the classical Indian tradition of Ayurveda (khalitya, palitya, bhringraj, amla).

Two lenses, one guide
The vocabulary of both traditions
The clinic’s terms and the classical ones, read side by side — not one against the other.

What’s inside
Cause and care, honestly framed
What the clinic sees
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.
Why hair turns grey
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.
Ayurveda & the classical tradition
The same two conditions read as khalitya and palitya — Pitta and heat, nasya, bhringraj (false daisy) and amla (Indian gooseberry) — alongside the Puranas and epics, where the first grey hair is a messenger rather than a defect to hide.
A practical eat / apply / live plan
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.
An assessment that builds your routine
A short question-by-question assessment turns the guide into a plan — drivers worth checking, tests to prioritise, and a weekly routine with a streak tracker and calendar reminders. Your answers stay in your browser.
Questions
Kesha, briefly answered
What is Kesha?
A free, long-form guide to hair fall and premature greying, read through modern dermatology and the classical Indian tradition (Ayurveda, the Puranas and the epics), ending in a practical eat / apply / live plan. It reads in the browser with no sign-up.
What does the Kesha assessment do?
A short assessment (up to 15 multiple-choice questions) turns the guide into a plan: the likely drivers worth checking, the blood tests to prioritise, an eat / apply / live list tuned to your answers, and a weekly routine with a streak tracker and calendar reminders. It is currently free to use, like the guide.
Where are my answers stored?
In your own browser, on this device. Kesha does not send your answers to CryoSim analytics - it only records which step of the assessment was reached.
Do I need an account or an app?
No. Kesha is a web page: open it in any browser, with nothing to install and no sign-up to read the guide. There are no ads. Your plan and routine are saved in the browser where you made them, so on a new phone or browser you take the assessment again.
Is Kesha medical advice?
No. It is a research summary of published dermatology and classical texts, and the assessment is an educational planning tool, not a diagnosis. Sudden, patchy or very early hair loss or greying should be seen by a dermatologist or physician.
