Toppik Hair Fattener is an amazing leave-in treatment that has been formulated to penetrate the hair shaft and "blow up" your hair for the fullest, thickest looking head of hair.

Toppik Hair Fattener 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.

Toppik Hair Fattener is packed with the highest concentration of pure Keratin protein of any of our hair care products.

It can be used in conjunction with Toppik hair fibers, though it's so effective that some users actually need less hair building fibres to achieve their full-looking head of hair (or none at all!).

Use Toppik hair Fattener every day to see a steady, continual increase in your hair's thickness. With its clean rinsing formulation there is no unpleasant build-up. Your hair will actually feel cleaner, look shinier and be easier to style.

118 ml. Lasts 3-4 months depending on usage.

Toppik Hair Fattener has been designed to be compatible with all other Toppik hair products, as well as topical treatments for hair loss like Rogaine and Minoxidil.
