Magic Sleek Step 1 Express Prepare Shampoo has all of the same benefits as traditional Magic Sleek and is targeted to the client who is interested in a hair straightening treatment that will last 3-4 months. It takes half the time of the traditional Magic Sleek. There are only two steps in Magic Sleek Express, which saves time for you and your client. Magic Sleek Express excels as a healthy, extraordinarily beautiful hair straightener. It is for the health-conscious client on the go, containing no caustic formaldehyde, no methylene-glycol, or any other toxic chemicals that produce formaldehyde when heat is applied.
