I like to use Head & Shoulders a couple times a month to reduce build up on my scalp. Most people don't like the smell too much but I quite like it. I like to play with semi permanent hair colors and use Head & Shoulders to help get rid of the color as it fades. I will also use Head & Shoulders to tone down the brassy color on my roots when I dye my hair. I always tell my friends to use this once or twice a month to refresh their hair.
