Inquire about the usage of - Cocamidopropyl Betaine (Coco Betaine) - Sulfate-Free Foaming Base can be used as สารชะล้าง can it be main? And how much do you need per 1 liter of water and which of these 2 types is more gentle? I'm not sure how much to order and how to use it. Because we are allergic to all brands of shampoos in the market. Nowadays, I have to order shampoo from abroad. Now I want to try it and use it myself. Please help me. Thank you.

The currently thought-and-existing ingredient is Suger thick herbal juice 40 g สารกันเสีย 10 Now there are three of them. I like to suggest that I need to use something more.

Let's ask in here but no one answered
