I’ve used this serum for a few weeks now and my hair feels noticeably smoother. It doesn’t leave any residue and my hair holds its shape better when I style it. The gloss is subtle but visible, especially in natural light.

Great for post-shower care. My hair stays hydrated throughout the day and I no longer see frizz at the ends. It works well with my regular styling routine and feels light on the hair.
