Just wish it were refillable

I use the full-size F-Layer serum daily, but I like this little one for travel. Just wish it were refillable - it doesn’t hold much, so feels like a waste of plastic.

My Forever Leave-In

Love the smell, and love how shiny, soft and hydrated this makes my hair feel. Tames my frizz without weighing my hair down.

Shiny, soft hair

Ordered this as a last ditch effort to get my color damaged hair (I'm now about 40% white so we add highlights to blend in the whites and avoid the harsh grow out) back to shiny and soft. Used with and without the De Luxe Reparative Masque (which provided about 10% of the improvement) and IT'S THE HOLY GRAIL PRODUCT. My hair stylist saw my hair and said this was the healthiest and thickest my hair has looked in a long time. I've spent the money and used every luxury hair care product that exists and while this is not the luxury scent they may offer or the beautiful bottle, it works.

Good serum

This product really does help tame my hair - it doesn't make a massive difference, but it is slightly noticeable. Great scent too!

Hello Weightless Hydration!

This truly is a “traceless” conditioning serum…so lightweight but so nourishing! I don’t feel like this serum goes out of its way to be “detangling”, but I do feel like it hydrates/repairs extremely well and absorbs instantly. It doesn’t leave hair feeling weighed down like some conditioning products do!
