Great product
Scent: Baobab & Rosehip, Size: 12 Fl Oz (Pack of 1)
Excellent product. It is really gentle and makes hair smoother, even used if used in hard water. It is overpriced though, and there isn't very much in the container.

Nice scent
Scent: Baobab & Rosehip, Size: 12 Fl Oz (Pack of 1)
I buy this for my curly haired 3 year old daughter because of the ingredients being on the cleaner side. It has a very nice light smell (we’re very sensitive to any fragrance). It cleans her hair without stripping it

Wouldn’t recommend
Scent: Baobab & Rosehip, Size: 12 Fl Oz (Pack of 1)
The product itself was fine I suppose, but the container is horrible. I appreciate they are trying to use less plastic but the carton got soggy, misshapen and gross quickly.
