Synergy's Peace Pure Shampoo 1000ml A shampoo specifically designed to improve hair quality. Personally, the good points! Scent: Champagne Apple Type: Amino acid-based surfactant = low irritation. ① Contains oil-soluble proteins keratin, collagen, and silk! → The keratin, collagen, silk, and other proteins found in most shampoos are "water-soluble"! Water-soluble proteins adhere to the hair but are easily washed away with water, whereas oil-soluble proteins are less likely to wash away and remain in the hair, making it easier to feel the effects. ② Contains levulinic acid. Levulinic acid is an ingredient used in most hair quality improvement treatments at beauty salons, which have become popular recently. This ingredient balances the moisture content and ion balance within the hair, making it moist and firm! Shampoos containing levulinic acid are very rare, so it's highly recommended! Especially recommended for those who regularly get hair quality improvement treatments at salons or those who have perms. Highly recommended for those concerned about hair damage. It's even better when used in combination with Peace Pure Treatment. ※ Doing something extra with this type of shampoo will increase its effectiveness! ※ Shampoo and treatment are also available.
