An ingrown hair is a hair that gets trapped underneath the skins surface. Blockage is caused by layers of dead skin piled on the surface of the skin, or dirt, body oils, etc, gets stuck underneath and inside the follicle. EXFOLIATION is KEY to preventing these annoying things!
Use your Merben Dry Bikini Brush before the shower (Dry Brush! Dry Skin!) in circular motions in the bikini & underarm area. It's also EXTREMELY beneficial to use all over the body!
