This formula has a pleasant smell and foams up nicely. The husband has found it lasts well also. I have used it occasionally myself and found it washes well and left my scalp free of irritation. I also found when I used it, the great benefit of removing the build up of products in my hair. I didn't realise until my hair had dried, it was so soft and really, really fluffy. The visual image of a Pomeranian that had just had a fright might help you with just how fluffy the hair was. That is not a comment on the product, more the lack of luck in the genetic lottery on my part.
