Shu Uemura Essence Absolue Overnight Serum 5 oz

This is beauty sleep for your hair. The serum soaks in without leaving residue on my pillow, and I wake up with hair that's soft, smooth, and frizz-free. It feels weightless but super hydrating — like a night cream, but for your strands. The morning results make it a keeper.

I put this serum on before bed and I wake up with hair that does not look slept on. I was using a hair bonnet previously, but I no longer have to use it to keep my hair from getting frizzy and tangled. The serum is rich, but I don't wake up with my hair looking greasy, as the serum absorbs into the hair overnight.
