How is Curl different from Smooth?

While both lines are designed to hydrate, heal, eliminate frizz, and block out humidity, Curl Shampoo and Conditioner is formulated specifically to address textured hair, which tends to be more brittle and prone to breakage (especially highly textured hair). Our Curl products are formulated with weightless hydration that facilitates curl formation without weighing down curls, in addition to naturally derived curl polymers for curl memory.   

Smooth is different in that it uses slightly more coating to reduce frizz and protect against high humidity. Additionally, both Curl Shampoo and Conditioner are silicone free.
