PROSCRIPTIX H Volumizing Shampoo Works great!! After first shampoo my hair was fluffy, soft, and thin spots on top front of head gone!! Only takes a small amount on hand and when rubbing in the scalp it expands quickly - volumizing. Shampoo has a nice just noticeable soft pleasant fragrance. Saw this in waiting room on TV. Completely Satisfied! Thank you Advanced Dermatology.
