The only shampoos that I feel clean my hair. I have noticed that whenever I stop using it and start using other common shampoos, I develop intense dryness. With 2-3 washes with head & shoulders, regardless of the scent, my scalp returns to normal. The only downside is that it dries out the hair and in combination with hair dye, it makes it look like straw, so I always use conditioner (not from the same brand because they are like the shampoos).
