I was waiting to see if
@mzteaze was still interested, if not...it's not a must have
Her question was along the lines of:
She saw a shampoo that was sold with only African Black soap and Shea butter and if I knew of a way to blend it together in a shampoo.
I had a similar situation but for a different product I'm working on and I've been using Polysorbate 80. It's similar to BTMS as it helps emulsify oil and water, but the difference is it doesnt thicken your mixture in the way that BTMS does. It is a water soluble emulsifier so it's best in shampoos or a water based spray.
I've been making my own rosewater and using it as an Emulsifier to combine the oil thats also in the spray, so I dont have to constantly shake it up when I use it. I find it to be mildly conditioning too.
There are a few old threads here where some members rubbed it directly on the scalp (DHT blocker) which also made me think it would be perfect in a shampoo for
@mzteaze by readimg some of her posts around the forum. I think Polysorbate 80 along with Rosemary tea, african black soap & shea olein oil would make a good shampoo for you.
