Toppek Hair Fattener from Spencer Forrest and Toppik has an innovative nutrient delivery system that actually adjusts to your hair's ph to open the hair shaft and allow an infusion of body-building Keratin protein. After the protein-charged formula is absorbed, the shaft is then "closed down" to seal in the thickening proteins.

Toppek Hair Fattener is packed with the highest concentration of pure Keratin protein of any Spencer Forrest hair care product. In fact, it's so effective that some users actually need less hair building fibers to achieve their full-looking head of hair.  Use Toppek Hair Fattener every day to see a steady, continual increase in your hair's thickness. With it's clean rinsing formulation there is no unpleasant build-up. Your hair will actually feel cleaner, look shinier and be easier to style. Toppek Hair Fattener can be used alone or in conjunction with Toppek Hair Building Shampoo and Conditioner. Toppek Hair Fattener is safe to use with topical treatments for hair loss like Rogaine and Minoxidil.
