What It Is

LEAVE-IN THICKENING TREATMENT FOR THINNING HAIR

KEVIN'S TIP: "It’s inevitable that over time hair will start to thin! To help the guys combat thinning hair, we looked to our highly-successful women’s product BODY.MASS with its scientifically proven eyelash plumping technology, and created a product exclusively engineered for men, but with all the same body-building benefits. THICK.AGAIN delivers thicker, fuller-looking hair, and thanks to its powerhouse of strengthening ingredients, will help improve micro-circulation to the scalp. To receive the full benefits of STIMULATE-ME and THICK.AGAIN, use the trio for 14 days, and your hair will look and feel transformed…in fact, it will be THICK AGAIN."

Rated 5 out of 5 by from Love it! Got so many compliments on my hair yesterday after I used this, it immediately made my hair look fuller. Super lightweight, didn’t make my scalp dry and flaky like other brands.
