Re: dandruff...
yea the key is to have clean hair. but if you wash out the natural oils (yes they are good for you) too much, a) the scalp tries to fix that by producing more oil. b) your scalp is drying out too much, and the flakes start to occur.
That is what my observation has been. I have oily scalp...but a big big dandruff problem. Garnier has this awesome line of shampoo and condition, Greasy Roots Dry Ends...try that.
