I want to create my own hair shampoo is this what I have, what do you think??
(Detergent) Sodium lauroyl sarcosinate (18%)
(Foam Booster) Cocamidopropyl Betaine (3.5%)
(Thickeners) Sea Salt (0.5%)
(Preservatives) Tea Tree Oil (2%)
Other ingredients: Rosemary Oil (0.25%)
Lavender Oil (0.25%)
I’m not sure about the Tea tree oil as a preservative and I’m also not sure about Sea Salt as a thickener, what is your take?
