Bottle didn’t work properly. The product doesn’t seem to do much for the hair.

I can live without this product doesn't make any big difference. If you need a boost for your damaged hair I better recommend a good leave in conditioner. 

I couldn’t see any difference with my hair after using it for few months 

I love the spray it works good on my hair. Before the bottle was made from metal not plastic , I liked packaging more.

I have very long, thick hair and this is a great product in actually making my dry ends look revived again after a week of styling.However, the pump on it drives me mad! It works for about 3 pumps and then it stops and I have to re-pump it several times before the product comes again. I've also got small hands and it's quite tiring pumping it out. I also don't like the smell - I find it a bit sickly and covers up the beautiful smell of my Kerastase.Unfortunately, I won't be buying it again and will try the Olaplex No.6 in the hope I'll get the same great results.
