Ok, i've Suffering 'dandruff' for years( may be 7 yrs, I'm 32,) (after shower my hair has flakes, if I don't wash it in 48 hrs it's totally greasy!!!), I have a friend with the same problem (she has health insurance, I don't), she asked her doctor how to treat it n doctor said 'i don't c flakes'.I tried many shampoos, home remedies...and a couple weeks ago got worse, I have many flakes (big ones) too visible :(, I just started using new clean and clear scalp shampoo for dandruff, the only difference it's that my hair it's smoother (in comparison w other dandruff shampoos), but no results :(
