Enriched with hyaluronic acid, this lightweight formula instantly absorbs into hair without weighing it down. The treatment creates a uniform film on the hair surface, resulting in silky, smooth, and manageable hair that lasts until the next morning. Best suited for those with dry, frizzy, or unruly hair who want quick results without heavy residue. Users may experience a slight warming sensation during application, indicating the product's activation.
