Why it is trending

- There is high consumer awareness of hair damage caused by pollution, heat styling, and chemical treatments like coloring. - Consumers are looking for products that offer preservation and protection rather than just cosmetic masking. - The popularity of bond-repair technology in other hair care products (like masks and shampoos) has created a demand for it in a daily leave-in serum format. - The desire for "glass hair" – a super smooth, high-shine look – fuels the need for products that can repair damage and create a flawless surface.
