Sandalwood Shampoo Formulation - Sulfate free shampoo
Introduction: Why Choose Sulfate-Free Shampoos?
Sulfate-free shampoos are gentle on hair and scalp, making them ideal for all hair types, especially color-treated or sensitive hair. They use mild surfactants that cleanse without stripping natural oils, while conditioning agents and hydrolyzed proteins nourish and repair hair.
This guide explains how to create a clear, sulfate-free sandalwood shampoo using natural surfactants, conditioning ingredients, and carefully balanced additives for a mild, effective hair care solution.
