Great hair starts here. This traceless serum—the first step post-shower—replenishes the all-important F-layer: the protective lipid layer that locks in moisture and gives hair its natural smoothness, gloss, and ability to reflect light. Weightlessly hydrates, repairs, and preps hair for styling thanks to vitamin- and mineral-rich Fruit Water Extracts and the nourishing Oil Botanical Blend.

Emily ★★★★★

Finally, a serum that doesn't weigh my hair down—the traceless finish is exactly what I needed. I can already feel my hair staying smoother longer since it's replenishing that protective F-layer.

Amelia ★★★★☆

My fine hair usually hates serums, but this one is completely traceless and actually leaves my strands feeling smooth without any greasy residue. It’s a nice extra step after washing, though I wish the bottle were a bit bigger for the price.
