HAIR MAXIMUM SHAMPOO is a highly concentrated herbal protein shampoo which pioneered the use of apple cider vinegar and panthenol in 1973. Rosemary and camomile uncover the natural highlights of your hair. The active protein system uses the highest quality wheat protein sized to be most compatible with human hair. This shampoo gently cleans without removing natural conditioners. The clean preservative system assures freshness and is designed to rinse out completely. Even with daily use there is no residual build-up.
