You can also message the sellers and ask them if they got their own website, as some websites dont always show up in google and are hidden.
The reason i know about this is because my sister inlaw is South African and i asked her what does she use to keep her hair so long and thick and she told me she uses coconut oil and body butter and mixes it with her shampoo. So i decided to try it myself and because i didnt have coconut oil and i had emu oil it worked the same. I was thrilled and happy with how my hair turned out. You can actually try different variations so i dont think it matters which oil you use.
I try to make different variations form time to time and i will use coconut oil next and see hwo that goes.
