I hate this new formula change. I love the one that came in the solid gold package. It made my hair look perfect. This new version is horrible. The new ingredient list is must shorter. It is missing many of the meeting agents that I liked.

Massive protein boost for damaged hair. Soft silky healthy hair is all about striking the balance between moisture and protein. Sometimes hair is lacking one more than the other, sometimes it needs both.
This packs a massive protein punch- which means if you have protein deficient hair it will take it from breaking easily and weak to strong silky and bouncy. If however you are needing moisture and not protein – it can make your hair feel almost brittle and stiff. If that’s the case try the joico moisture recovery or kerastase nutritive range. Saves my hair everytime! ❤️
