I want to ask
สีละลายน้ำ Cosmetics (Water-Soluble) that are sold can be mixed with compounds such as
ethanol , Can I Distilled Water? Well, I'm going to make a water based product for my scalp and want to color it beautifully because the main ingredient is colorless. So I want to ask (Water-Soluble) that are sold can be used to mix and if applied on the scalp or skin will the color stick or not?
