When I tried it I wasn't impressed, it is like gel/water (but smells heavenly, energizing) and didn't expect much. But after few uses my hair feels amazing. You (almost) can't over do it, because of gel like structure and hair does absorb it very quickly. Perfect for fine or oily prone hair that don't do well with leave in conditioners or oils.

I have really damaged ends, I do hair masks once in a while but it doesn't really fix my ends, especially since I've done multiple straight perms (and am extremely due for one). I do feel like the serum hydrates and fixes my ends but just a bit, but I can't really tell since I feel it would be better for my hair if I just chopped if off :(, but it smells really good and has a pretty good value for the amount you're getting. P.s. I would also recommend the Gisou honey hair oil but it is a but pricey so...
