What it is
A 2-way formula that can be used as a leave-in hair oil or mixed with the in-bath "Reveal Booster Hair Mask (3 types)". Recommended as a weekend treat when you are concerned about hair damage and dryness! Customize it into a special care with the increased moisturizing effect of the rich oil. Contains 3 types of keratin x heat protection ingredients x 3 types of organic oils. By combining multiple hydrolyzed keratin ingredients, it thoroughly repairs the hair from the core. Formulated with heat care ingredients such as γ-lactone and meadowworm oil to protect from heat damage while also repairing it. Organic oils such as cactus oil, camellia oil, and baobab seed oil protect hair from dryness and oxidation.
