Grip-Tuth (pronounced Grip-Tooth) Hairtainer sidecombs are the best sidecombs in the world. Each Grip-Tuth sidecomb is handcrafted so its teeth touch through the middle of the comb. This makes Grip-Tuth different and better than all other sidecombs. Only Grip-Tuth combs have touching teeth. The touching teeth g-r-i-p gently, and securely hold all hair types. Grip-Tuth works equally well on fine and thin hair as well as thick, coarse and hard-to-manage hair.
