I having dandruff & itchiness. I can feel my scalp in tense situation & it cause me so pain sometimes. I used selsun blue for so long, doesn't help.

DANDRUFF & ITCHINESS. HAVE YOU SEEN A DERMATOLOGIST YET? IF NOT DO SEE ONE. I DO NOT KNOW HOW OFTEN YOU SHAMPOO BUT I WOULD GUESS THAT IT IS NOT TOO OFTEN. I RECOMMEND THAT YOU SHAMPOO DAILY -- YES, DAILY -- FOR THE NEXT WEEK AND THEN AFTER THAT, CUT IT DOWN TO THREE TIMES A WEEK. TRY AN OVER-THE-COUNTER TAR SHAMPOO. IF IT'S NOT BETTER PLEASE SEE A DERMATOLOGIST. BEST LUCK.
