I’ve used this on my light blonde hair that was very frizzy and damaged. The treatment smoothed it beautifully without dulling the color. It felt gentle and didn’t leave my hair looking greasy. After a few weeks, I noticed less frizz and more shine. I’m happy with the results and would recommend it to others with similar hair types.

My hair is fine and a bit fragile, and I was worried about the treatment being too harsh. This one worked well—no color change, and my hair felt softer after use. The spray helps with hold and adds a nice finish. I did need to use a heat tool at a lower temperature, but it was manageable.

I’ve tried several keratin treatments before, and this one stands out. It’s gentle on blonde tones and doesn’t fade or yellow the hair. The conditioning is noticeable—my hair feels stronger and less brittle. I’ve used it twice now and still see great results.
