Great product
Scent: Baobab & Rosehip, Size: 12 Fl Oz (Pack of 1)

Wouldn’t recommend
Scent: Baobab & Rosehip, Size: 12 Fl Oz (Pack of 1)

The only one that I keep buying. Use to buy from wholefood but they’re sold out and luckily I found on amazon. I love the smell and it keep my hair moisturized. Feels much better than those one sell in CVS!
