## Description

desertcart.com: Joico Defy Damage In A Flash 7-Second Bond Building Hair Treatment | With Liquid Keratin | Quick Bond Strengthening & Protection | Color -Safe | Unique Liquid-To-Crème Formula | 6.76 Fl Oz : Beauty & Personal Care

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: So impressed! - 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!
