Curls By Cass @ Loft Studios. Owner, Cassie Rose Carnahan, licensed Cosmetologist since 2002. I specialize in natural curls & Goldwell hair color. My training includes the Deva methods and cutting technique. Hair is cut dry, without tension from combs, to preserve its naturally curly shape. The dry hair cut is followed by the Deva 3-Step (cleanse, hydrate, style). I keep up with continuing education for Goldwell Hair Color. I prefer to only use ammonia free hair color on all of my naturally curly clients. Ammonia based and high level peroxide hair color can lead to extremely dry, damaged hair. My 1st goal is to teach clients to love the natural texture of their hair. My 2nd goal is to teach them how to achieve, and maintain truly healthy hair (whether naturally curly or naturally straight).
