The Cleansing & Purifying Treatment is a colorless treatment that optimally prepares the hair for coloring with the Healing Herbs Hair Color and stimulates hair growth in a natural way. It serves as a deep cleansing of the scalp and hair. Thorough cleaning is essential, especially with chemically treated hair. The Cleansing & Purifying Treatment is also ideal as an anti-hair loss treatment. It is also ideal for itchy and inflamed scalps, neurodermatitis, psoriasis, quickly greasy hair roots and dandruff. The Cleansing & Purifying Treatment can also be used as a single step, independently of the coloring process with the NOELIE Healing Herbs Hair Color.
