Olaplex No. 0 Intensive Bond Building Hair Treatment, Repairs, Protects, & Strengthens All Hair Types, 5.2 fl oz

Works. I got this to use with the Olaplex sample kit. Together with the rest, perked my curls right up!

Es fuerte no aplicar en el cuero cabelludo

No me funcionó, luego de aplicar todos los pasos no observé cambio en mi cabello

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

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.

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

This review is mainly about trying to apply the product using the nozzle that is attached to it. The product comes out in such a strong, straight harsh stream of liquid that much of it gets wasted by dripping or just being misdirected. I don’t know why it was manufactured with this, but I would not buy this again due to product waste Because of a bad bottle design.To be honest, I can barely use the product because I can’t seem to properly apply it for the cost of it. This seems pretty bad.
