Sometimes hair falls off or thins out in a small patch on the scalp or on the moustache for men.This is also known as Alopecia.It is known as "Penu Korukudu " in Telugu.
This particular remedy was recommended by Panditha Elchuri:
Rub a soap nut on a rough stone with salt water and collect the thin paste and rub it on the hair loss patch twice or thrice a day.The salt used must be sea salt.
Hair growth starts in 3 days after this treatment.
