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 shampoo for fine hair optimizes pH and increases internal strength to reinforce the core of fine hair for resilience and elasticity. The hair care 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.

  • Good Shampoo!
Size: 13.5 Fl Oz (Pack of 1)
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.

  • Great product, irresponsible delivery
Size: 13.5 Fl Oz (Pack of 1)
love the product, but Amazon sends it irresponsibly. I got my order and it had a broken pump and had spilled through the entire package (luckily everything was in it's own bags, but the bottle was nearly empty). I had to escalate my return because Amazon was forcing me to return the mess I'd clean up and threw away. They sent another, which was also open and spilled out in the package, but the pump still worked. I would like to return it too, but the same thing would happen a 3rd time for sure. ... show more

  • Awseome Nexxus Shampoo
Size: 13.5 Fl Oz (Pack of 1)
Nexxus Unbreakable Anti Breakage Shampoo was a hair saver/ salvage whatever you want to call it. At 65 plus, I was using a high quality shampoo with sulfate in it for at least 30 years. And, I guess for a combination of reasons, my hair began to break, drastically. After using this shampoo for one week, the change was notible, with a substantial decrease in hair breakage. Together with the Nexxus conditioner, problem solved!!! ... show more
