JoicoDefy Damage In A Flash 7-Second Bond Building Hair Treatment | With Liquid Keratin | Quick Bond Strengthening & Protection | Color -Safe | Unique Liquid-To-Crème Formula | 7.1 Fl Oz

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!

I use this in combo with the Joico K20 Power Masque. After one use you have all new hair. After 2 uses I’m pretty sure you become a Princess of Genovia. I have yards of very curly red hair. I was considering getting a Brazilian blowout. These products have completely changed my hair and I no longer feel like I need to spend the money on the blowout. They make it immediately soft, tangle free, easier and quicker to blow dry, and possibly make me just a more interesting human. Buy them both now.

Smells great. Quickly foams up and works nicely on my coarse thick hair.

This is my 4th bottle purchase. This stuff is Fantastic Fabulous Great okay. If your hair feels dry damage or anything you need this. It will save it. My hair was breaking after one use it stop rinsed it out my hair was shining moisturizing full of softness and smelled so nice. Just use a little bit. Follow directions and have happy hair.Price not bad

Super impressed! I recently had to use a very harsh color remover twice in quick succession before dyeing my hair again, so my hair was pretty fried. The before and after pics are in very different lighting, but the point is to show how before my hair was limp, brittle, and dull. After, not only is my hair super shiny and hydrated, it actually looks shorter because my curl is bouncing back! I will say that because it’s supposed to be applied directly to the hair, it’s a little difficult to use on shorter lengths. Would be easier to pour into my palms and work through that way. Still, I’m really happy with the results and will definitely keep a bottle of this around. (Smells good too!)

A 7-second bonding hair treatment... right??? But then again, it is Joico and Joico never disappoints. I was blown away by the results. My hair is in the process of turning a lovely salt and pepper color but the texture doesn't put up with much. It has been quite an adjustment for me. I noticed this product by mistake and it intrigued me. What the heck, right? Wow did it work. Instantly my hair was smooth, soft, and noticeably stronger. Yes, after a 7-second treatment, a dry and style. There was less breakage right away. I'm completely sold. It may respond differently with various hair types but it sure worked magic on mine. Who knew :)

Product works just as described. Use it every other day and it's definitely helped smooth out my hair.

I used this in the shower and it got hot immediately and i rinsed it immediately.And it damaged my hair. Made it very dry & poofy. Even the texture changed. I so regret putting this in my hair because I was iffy but I saw the reviews n had high hopes for it but no. Maybe my hair didnt like it because it doesnt look happy.
