HairPlex has a very low pH, about 3. It's still low when mixed with other ingredients. Is there any Preservative Free that can be used with HairPlex? But if you have to use it, please be a Preservative Free type)
I don't know if you received the question or not. I haven't received an answer yet. At what number can I call and inquire? Received an answer and will place an order together.
hello
Mild Preserved Eco is suitable for formulas with a pH higher than 4. You can adjust the pH in the formula slightly.
