Oyin handmade and Shea moisture do contain proteins. Be aware that there are natural sources of protein. Coconut oil, avocado oil, Wheat germ oil, hemp seed oil all are huge sources of protein. Go to mountainroseherbs.com and look at the information about each oil. You can also look up any oil you are interested in individually on google. Finding products with no protein in non-natural products is easy because you just look for key words like "protein" "hydrolyzed" etc. In natural products, it requires a bit of knowledge in order to choose because you have to know which ingredients are natural sources of protein. The natural ones are less potent because they are not specifically designed for the hair shaft however, if your hair is VERY sensitive like mine, then you should be careful about the protein regardless of the source.

Hope this helps

My hair loves Pure Shea Butter, my hair adores Extra Virgin coconut oil, but I believe wheat germ oil and soy bean oil are either too strong or too much in the product. I had purchased so many Carol's Daughter products only to find it was not benefiting me, I would still have unmanageable dry hair after spraying Black Vanilla leave in. The Tui leave in, did help some with detangling. And the Tui Smoothie was just awful. My relaxed hair loved Silk Fusion (Smooth N' Shine), but I have not seen any great results when I recently used it. I am going to eventually figure this out...
