Professional-grade keratin care at home

Discover the KERATIN RESEARCH Brazilian Keratin Hair Straightening and Smoothing Treatment, packaged in a practical 4 oz bottle (120 ml). This formula blends Keratin proteins with Argan oil and Collagen Amino Acids to help hair feel smoother, stronger, and more manageable while preserving a natural look.

Real-life use scenarios

Imagine mornings with less time spent styling and a smoother, more uniform appearance. The treatment can contribute to hair that dries efficiently and maintains a refined look, even on days with lighter styling.

How to use (quick guide)

1. Start with clean, towel-dried hair; work in sections for even coverage.
2. Apply from mid-lengths to ends, avoiding direct contact with the scalp.
3. Leave for the time indicated on the packaging, then rinse thoroughly.
4. Style with your preferred heat tool to seal the smooth finish.

Maintenance and care

To help preserve results, use a mild, sulfate-free shampoo and conditioning routine. Limit harsh rubbing when drying and consider complementary serums or masks designed for smoothing and protection from environmental stressors.
