S4 Smoothing Treatments are available in 2 formulations.
FLAT IRON FREE and INFINITY formulas. These work on most hair types from the most delicate to coarse resistant. Your client will love the smooth, soft, shiny, frizz-free results.

FLAT IRON FREE is ideal for fine to normal hair texture, including bleached/highlighted hair and does not require the use of a flat iron.

S4 smoothing treatments provide comparable results to traditional salon Brazilian-type keratin treatments when it comes to reducing curl & wave, removing frizz and smoothing hair – but without the harmful chemicals and in half the chair time without the need for special ventilation. Because S4 smoothing treatments work from the inside out, the hair is not only smoother and straighter, but also healthier looking and more manageable.

FLAT IRON FREE — Fine to Normal including COLORED, DELICATE, FRAGILE BLEACHED, HIGHLIGHTED & DAMAGED hair/Slight to Extreme Frizz all without the use of a Flat Iron
INFINITY — ALL HAIR TYPES including COLORED, BLEACHED, HIGHLIGHTED & DAMAGED hair/Slight to Extreme Frizz

Stylist Trial Kit includes:
• One 8-oz tube of treatment (enough to do 2-4 clients) of either Flat Iron Free, Infinity
• One 4-oz tube of S4 Styling Crème
• One 8-oz tube of S4 Shampoo
• One 8-oz tube of S4 Conditioner
