Not for me
Scent: Baobab & Rosehip, Size: 12 Fl Oz (Pack of 1)
I appreciate what they are trying to do with the carton however, it’s more splash proof than water proof. The smell is off for me as well. I really wanted to love this product because I love the company but this one is a miss for me.

Great moisturizing shampoo for damaged hair
Scent: Baobab & Rosehip, Size: 12 Fl Oz (Pack of 1)
It is a good non toxic shampoo and conditioner, but be cautious it's very moisturizing and not good for oily hair. It works best for dry and damaged hair. A little goes a long way, so don't over shampoo. To my surprise..the container won't get soggy in the shower!

Super light and doesn't come off with sweat
Style: Tropical Coconut
Great stuff. Its super light, once the smell wears away you forget you every applied sunscreen. It also goes on super easily and doesn't leave my face super shiny. To my surprise it also doesn't come off easily with sweat. I've used other brands and the moment you sweat it just all washes away. Overall great stuff. The fragrance is a bit strong for me but I usually use unscented stuff so I'm extra sensitive to it. Good thing is the smell does wear away after a little bit.
