• Two steps: Step 1 conditioning and prep; Step 2 sealing and smoothing
• Formaldehyde-free, vegan-friendly, cruelty-free, paraben-free, and dye-free
• Contains natural extracts to support smoothing without heavy residue
• 3.38 fl oz / 100 ml kit size designed for multiple treatments

What you may experience and how to care for it

Frizz control can persist for months when combined with a suitable hair-care routine. A silky straight look may last for weeks, and hair often gradually resumes its natural texture as the treatment settles. There are no downtime restrictions, so you can wash, color, exercise, swim, or wear your hair in a ponytail right after use.

• Potentially up to 3 months of frizz control with proper care
• Potentially up to 12 weeks of smoother, straight-looking hair
• No waiting period after application; everyday activities are fine
• Suitable for all hair types

Safe, conscious formulation

The formula is vegan-friendly, cruelty-free, paraben-free, dye-free, and formaldehyde-free. It uses extracts from natural ingredients to support a smoothing result, with no harsh additives.

Note: Results vary by hair type, previous treatments, and maintenance. For best outcomes, follow instructions and pair with color-safe, gentle-care routines.
