Really effective for colour damage
I use it for colour damaged and dry hair, works very well, I swear by it now. Its also very potent, make sure to only use a couple drop especially when starting out they go surprisingly far. Even a few drops extra can make your hair greasy.

Not for low porosity hair; minimal impact
Took stars off because didn’t absorb in low porosity hair, cost, and minimal impact on my wavy/curly hair.
