Review: This has been a miracle - This has been a miracle for my hair. My hair was so dry and brittle with breakage. My hair stylist used it on me at the salon and suggested it for continued use. When I returned in 28 days she was jaw dropping amazed at the difference of softness, strength and no breakage. Softness you can feel to the touch and see the beautiful shine. I wash my hair every 3 days.
Review: A must buy for bonding and softening ends of hair - Thos product is amazing! I color my hair every 6wks so lots of breakage and dryness 2. Washed with Joico youth shampoo n then same conditioner. After, I rinsed and applied this product to mainly ends of hair. Flipped it over and used nozzle to apply super small amount. Combed it thru from ab midsection to ends (avoid roots or will b too soft to style). Waited 7secs rinsed thoroughly. Blow dry and styled..my hair looked like it did when I was in my 20's. Shiny, bouncy, no weigh down. It truly floored me!!! I've used it everyday since I received and after every wash Im just as impressed. Highly recommend and will buy again. ****Lil note..follow instructions exactly and stay away from roots (unless u r doing a sleek backed up do. It will be too soft to do nething else if u do roots.

### ⭐⭐⭐⭐⭐ So impressed!
*by A***3 on February 22, 2025*

Wow, this stuff really exceeded my expectations. I feel like my hair is weak (lots of hair, but the individual strands are very thin) - I have highlighted my hair for years and always wind up with a lot of damage and frizziness at the ends. I order a million different expensive hair products, hoping each one will make a difference but I'm never usually impressed and they never seem to do much. This product made such a difference! And it was so fast and easy. I have countless products that need to be left in for 5, 10, 15 minutes and those are a pain. This took literally 7 seconds and when I got out of the shower to dry my hair, it was so smooth and frizz-free. It really seemed to bond my ends. Great product and I'm so impressed!
