What it is
Amino Master Deep Repair Treatment Refill *Please be sure to use up the entire bottle before refilling into the Amino Master Deep Repair Hair Treatment pump bottle. Intensive care for severe damage. It provides intensive repair from deep within damaged hair, transforming even thin, weak hair into beautiful, bouncy, and lustrous hair. ◆Contains meadowfoam-δ-lactone, a heat repair ingredient commonly used in the beauty industry, whose repair power increases when heat is applied. It gives hair bounce and strength, leading to beautiful hair from the core. Recommended for: Thick, voluminous hair Those concerned with damage and coarseness Those looking to reduce frizz Those who feel their hair is thinning and weak Those seeking a smooth, lustrous, manageable look *Contains 19 types of amino acids*1, which are the main components of hair, for a moist, smooth feel even after washing *Contains two main hair proteins, keratin (raw keratin and hydrolyzed keratin) (repair ingredients) *Contains CMC ingredients (ceramide NG, cholesterol, quaternium-33: repair ingredients) that act as a pathway for nutrients and moisture within the hair...CMC generally decreases gradually with age. This decrease reduces hair's ability to retain moisture, making it dry, unmanageable, and prone to frizz. *Contains 8 moisturizing ingredients: Double hyaluronic acid (low molecular weight hyaluronic acid, 3D hyaluronic acid), organic coconut oil (palm oil), 4 honey-based ingredients (propolis extract, royal jelly extract, honey extract, honey), and olive fruit oil. *Contains UV damage care ingredients (moisturizing ingredients): Sanguisorba officinalis extract, Scutellaria root extract. *Peony & rose scent. [Texture] Slightly heavier than the Moist Treatment, this beige treatment feels firm on damaged hair while also providing excellent growth. For best results, thoroughly drain your hair before application to prevent the treatment from running off. *This product is a refill; no bottle is included.
