Results your clients will love month after month....Better results than other smoothing treatments.

Let's take a second to talk about the S4 Styling Crème now. So, usually what I do after I get out of the shower, I brush my hair, I place a nickel size on the palm of my hand, and I start from the bottom and I work my way up. I let my hair air dry and when it dries you are going to see that it helps reduce the fly-aways, the frizziness, and it helps your hair stay straighter and healthier. It's a must.

I've been working with all types of keratin for the past 10 years. When I first heard of S4 I was a little bit skeptical because I've worked with other formaldehyde free keratins that just were not effective. They didn't last more than a month or they didn't last at all. S4 delivers everything that it promises...

S4 is so fantastic. They have 3 options and one of my favorites is the Infinity because I specialize in blondes. I want my blondes to have healthy, shiny hair. It lasts three to five months — they're happy, I'm happy. I'm making money, money, money in half the time! It's fantastic...try it!
