Optimum Advanced Keratin Recovery Neutralizing Shampoo 33.8 fl. oz. (1 l)

I purchased this neutralizing shampoo to use with the Mizani Butter Blend Relaxer. Mizani's brand neutralizer was rather expensive compared to this stuff. This bottle at 33.8 oz will surely last me quite a while since I will only use it when I treat my hair with relaxer. The color indicator made it very easy to use and it left my hair feeling great. I have zero complaints since it did exactly what I had hoped it would do. This is certainly the best value I've seen when it comes to neutralizing shampoos.

Conditions hair wonderfully! You can actually feel in your hands the change to softness in your hair as soon as the shampoo is applied to the hair. Love it!

I received this product today and I could not wait to use it. I was very pleased with the smell and the results. It comes out very thick, so you only need to use a small amount and the lather is wonderful. I hadn't use this product for years and I missed it. Now I know why I liked it so much to begin with. I would say it works and was very much worth the money.

Great B' Day gift for my friend, she does this perm stuff every 3.5 months so I bought a boat load. Great brand and I told her to shop at Amazon to shop for more.

I was disappointed with the shampoo. It left my hair dry

This is great!! It cleans your hair, while leaving it soft. It moisterizes without weighing it down or making it greasy.

Works better than any shampoo I ever tried and I recommend this shampoo for regular use it also leaves my hair soft and silky.

This product is awesome. Having such a big portion allows for multiple uses.
