5 Stars
This was a lifesaver!
The first picture is my hair in late December and the second is my hair February 17th. I received my bottle February 3rd. I ordered this as a final effort to save my hair before I would have to just cut off the damage (accidental frying from bleach, I did it myself so there’s no one else to blame 😂). The first week I wasn’t using it right so I didn’t see the best results. I check the instructions again. Turns out I was supposed to basically rub it around in my hands like you’re warming up lotion before applying. That’s when I saw practically INSTANT results! Use on damp hair after shampooing, but do NOT condition! I’m so happy with the improvement!
Thank you for your feedback
