    • LOVE‼️‼️‼️
Size: 3.38 Fl Oz (Pack of 1)
I am absolutely in love with this stuff!! I 1000% recommended and I would give it 1 million stars if I could. My hair has been suffering because I changed my shampoo so I went back to Nexus and I got this stuff for a leave and it is amazing. It doesn't make my hair greasy or flat and I have very fragile and fine hair. I will definitely be rebuying and I will own this Forever now, I am a Forever customer. ... show more

Size: 3.38 Fl Oz (Pack of 1)
Do not, I repeat do not waste your money on Kerastase. You can buy two of these for one of those. This is an exceptional product. You can see the difference while you are applying it. I will definitely repurchase

    • Probably works!
Size: 3.38 Fl Oz (Pack of 1)
Smells nice and probably helps? Not sure. I will probably stick with my wash out conditioner however. A bit heavy since you leave it in.

    • Works Well and for less than other brands. Will keep using. Extends Blow Out even w/wavy hair.
Size: 3.38 Fl Oz (Pack of 1)
I read an article on the overnight serums that seemed to promise having your hair look less frizzy and messed up when you wake up in the morning. Most of them were expensive (Crown Affair, $58) so I did some looking around and decided to try Joico's version ($29 and free shipping). My hair is wavy and will tend to curls if treated right, but when I blow it out inevitably overnight it frizzes out and doesn't hold the blow out. Half wavy and half straight and never in the "oh that's so cute" version you could imagine. I've used Joico Defy Damage for about 2 weeks. Putting it on the ends, and middle of my strands but not the scalp/roots and brushing my hair right before bed. My DIY blowouts have been holding up for 2-3 days. Just get up and brush my hair and go. That is not normal and the only thing that changed was using this at night. It may not look like I just had my hair done, but it's close and I haven't had to just shove my hair into a clip to get by an extra day. Big fan. Will keep using. ... show more

    • Shiny hair!
Size: 3.38 Fl Oz (Pack of 1)
I love Joico products 😍 at 70 years young, m hair has been thru so many trends from perms to braids. I didn't have this product in my routine,so I trusted Joico. I love it because it does work! I spray on my hair at nite, after taking my makeup off and brush thru my hair ,then the next morning shampoo my hair. This product makes my hair soft and shiny and looks so healthy and has a great smell! This product doesn't leave any residue. I suggest this product along with other Joico products. You really can tell a difference! ... show more

This product smells great and does great in my hair, but the pump just stops working after a while. It’s hard to get out of the bottle because of the packaging
