OlaplexNo. 0 Intensive Bond Building Hair Treatment, Repairs, Protects, & Strengthens All Hair Types, 5.2 fl oz

I feel as if this single-handedly saved my hair throughout my blonde journey!

Seems to be helping my hair. Easy to use. A little costly.

I'm so glad I learned about this product. My hair is thinning and I have some problems with damaged hair That is very coarse and breaks easily. This product started changing my hair on the very 1st Time I use it. It seems a little expensive but it's well worth it! I Follow the directions and use it as I am supposed to and have been amazed at the results. I can get away with washing my hair just once a week so that's how often I use it. I Use it every time I wash my hair. Works really well and does really exactly what it says. I've tried several other pre treatments. This one really stood out as the best by far.

Mr encantó, mi cabello quedó bello

Great product, especially when used in conjunction with No.3, 4&5 Shampoo and Conditioner, and No.8. It makes my hair feel great!I do wish that the company would change the sprayer nozzle however. I have long hair, and this product comes out in a solid stream. You're supposed to spray evenly and wet all of your hair with the product, without saturating it. The spray is difficult to spray evenly, and I feel that it would be more successful without using as much product at once, if they would change the way it sprays. For that reason I only gave a 4 star. I would really love for them to make the spray more even instead of a solid stream, so I'm not wasting product as it's already very expensive with having long hair and using more product.

My hair changed 80% since the first time I sued the products I’mIn love with the results I have been getting since I’m using them it’s highly recommended you willLove them if you hair is damaged you will see changes since the first time you use them .Amazing progress since I started using this products

This product is very watery and sprays all over when applying. It is to be applied 10 minutes before washing, left on and then washed out. It does not work to remove tangles, etc. I have only used it once, and did not see any real difference. It would be better if not as watery, so was easier to spray on and work in without spraying it onto. nearby mirrors or walls.
