Sarah : i have been suffering with dandruff for more than 3 years now, it typically started when i got rid of all the lice in my head and over the years its just getting worse and worse , doctor scared me and said it will never go away?

Dandruff is the result of skin cells of the scalp failing to shed naturally when skin oils and other factors let them build up. Dandruff shampoos contain chemicals that cut through the attachments of old cells and help them separate in a more uniform fashion, often undetected to most people. Dandruff should be seen as a natural part of getting older. It is not a disease but a hair care issue.
