If your hair is fine or thinning then it needs a little helping hand to get it looking its most voluminous. Nioxin Bodifying Foam gives you thicker, fuller looking hair as well as locking style in place with a medium hold. The ultra lightweight formula will leave you with the illusion of fullness, without being weighed down or left with an unpleasant sticky residue. Nioxin's signature Pro-Thick technology uses a complex of thickening polymers which coat each strand of hair, filling gaps between them for thicker-looking results. Your hair will look fuller, healthier and alive with body, bounce and freshness. - Nioxin Bodifying Foam
