The Neutral Zone pH of Grund ReviveTH Shampoo empowers maximum deep cleansing of the scalp and follicle. The ProFacil Complex then returns the hair and scalps pH to its natural pH5.

Grund ReviveTH Shampoo thoroughly cleanses sebaceous secretions and subcutaneous cholesterol out of the follicle opening. These substances can be obstructions to normal hair growth and cause the hair to go into catagen and telogen prematurely. The substances can also cause a follicle to change such that it produces a finer vellus type hair. Grund ReviveTH Shampoo extends the life cycle and maximizes the useful life of the hair. The follicles continue to produce maximum diameter hair as well for the full length of the hair growth cycle. This makes the hair thicker and richer.
