Hello, the formula can be mixed. but in case of wanting to change from
Sulfate Free Shampoo Base to
Foaming Tea cleaning performance may be lower. may have to consider increasing the proportion of use
Foaming Tea even more because of natural cleaning agents. The efficiency is not the same as chemical cleaning agents. However, in this formula, in the case of using
Sulfate Free Shampoo Base may not be needed up to 30%. 20-25% first, if found to be clean enough You can consider increasing it to 30% because the rate of 30% is usually used in liquid soap or shampoo formulas. which has a need for cleaning efficiency higher than the cleansing formula
