What Else You Need to Know

This professional smoothing treatment is formulated with Keratin-Alpha Shaper and amino-acid chains to deliver salon-quality results. This is a breakthrough hybrid of texture and hair care. Contrary to classic conditioners or masks, it deeply penetrates inside the fiber and smoothes the hair at the keratin alpha level, the deepest level of hair. It is free from alcohol and artificial colorants, and suitable for all hair types including keratin-and color-treated. It is safe to use during a color appointment.

Note: This product has a technical smell due to a small amount of cysteine in the formula, which supports the anti-frizz, smoothing benefit.

How to use: 

1. Progessive treatment, use once a week after shampooing. Alternate with a hair mask on other wash days.

2. Shake the bottle well before use.

3. Section hair into two parts and apply evenly from lengths to ends on each section. Use 1 - 1.75 ounces, depending on hair thickness and length.

4. Leave on for 10, 15 minutes, and then rinse thoroughly.

5. To activate the smoothing technology, blow-dry completely and use a flat iron. Use weekly for 4 uses, then once a month to sustain the frizz-control. Stop using if the hair feels dry.
