Cosmoprof is a perfect supplies store for any liscensed cosmetologist. Unlike Salon Centric, they have other really good color lines such as Goldwell (one of my favorites). They sell the very popular, Nioxin line, including Nioxin Diamax hair thickening treatment which is a huge seller in the salon I work in. The service is great and the staff are always so helpful in answering any questions that you may have. All in all its definitely a place worth checking out for any stylist.
