Fill your Glam Comb with your favorite hair mixtures. Many of our customers like to custom blend their own oil mixes, in order to use the teeth of the Glam Comb to distribute the oil directly to their hair strands and their scalp. The Glam Comb's squeezable bottle makes it easy for the product to flow through the bottle, and into the comb of the teeth, directly to where you need it to be.
