Wish this existed a decade ago! A must have

I started coloring my hair as a teenager. If this existed back then, it would have saved my hair a million times over back then during all the mishaps! I recently used it on my hair after it got a little too crispy after bleaching. In the past, when this has happened, I’d use olaplex 3 but this time I decided to try this….and my goodness, it is the best repair product I have ever used. I’m honestly shocked and wondering if it’s too good to be true! Sticker shock sucks, but honestly if you damaged your hair, give this product a go

Must have

My hair was very dry and starting to feel like straw from the bleaching. After my first use I noticed a significant difference and my hair felt softer. It looked so much better, with a lot less frizz after blow drying. drying.b I have have 2b
