Description

Hair is made up of protein. Every touch, every treatment, every style you love—it all rewrites your hair’s protein. When protein is damaged, hair’s look and feel are compromised. That’s why Nexxus uses protein science not just to repair hair but to restore its ability to perform. It isn't about one perfect hair day. It's about a lifetime of healthy hair, built strand by strand. Fine and thin hair is naturally more vulnerable to breakage. Its internal cortex is narrower and has fewer protective cuticle layers, making it prone to frizz, tangles, and structural weakness. UNBREAKABLE, our strengthening collection, is powered by DURAPLEX FORTIFIER technology with a thickening complex—a breakthrough protein matrix that increases strength from within. This system helps reduce breakage with 97% less hair fall and build fullness from the inside out. This anti breakage conditioner for fine hair optimizes pH and increases internal strength to reinforce the core of fine hair for resilience and elasticity. This hair conditioner also has bond-building power so you can revive styles anytime thanks to reformable bonds. This hair care shampoo and conditioner system also provides cuticle protection to shield against external damage and delivers weightless volume that lasts all day without weighing hair down. Flexible polymers add volume and lift, so hair looks thicker, feels stronger, and styles effortlessly. Nexxus, the protein science behind powerful hair since 1979.

  • great product
I have been using this shampoo and conditioner for 2 years now and love it! The smell is not my favorite though

  • Losing less hair!
Since I've started using this conditioner I've noticed that not as much of my hair is falling out or breaking off. I'm very pleased with the product and I even like how it smells (My husband noticed too)

  • Good Conditioner!
I like the way my hair feels after using but the smell does not go away. It smells really good but I don't like smelling it all day - a little too powerful for me.

  • Phenominal Nexxus Conditioner
Nexxus Unbreakable Ati Breakage Condioner and Nexxus Unbreakable Shampoo solved my hair breakage and loss problem at 65 plus years of age. No sulfates added is what I needed. I noticed a difference after one week of usage. Thank you Nexxus Brand!!!!!

  • Smells odd and doesn’t work very well.
It works but at a cost. The shampoo dried my hair out terribly. I had to use the conditioner more often and it really did not do much to fix the dryness. They both also have a weird smell. Not something I would recommend.

  • Best for fine, thin hair!
If you have baby, fine hair that breaks off easily, this is for you. I've been using it for almost a year now, and my hair looks much healthier. My hair isn't breaking off like it was. My hair is longer than it's been in years. I highly recommend this conditioner with the Shampoo, and the spray that you leave on after you get out of the shower. Well worth the money. ... show more
