The brush is made to adsorb moisture from your hair. So, before you add any serums or anything to your hair for blow-drying and after you towel dry use this brush to reduce the amount of moisture in your hair. this will speed up drying time drastically.
This brush is designed to absorb the moisture from your hair after washing it, while you brush out any tangles you may have in your hair. My daughter just received this yesterday in her Holiday VoxBox and so far we only have good things to say about it. Works very well!!
