What: Kérastase Noctogenist Serum Nuit, $65
Why: After revitalizing my dull hair, my love for the miracle-working Kérastase now knows no bounds. And my hair was tired… tired of flat ironing, highlighting, dyeing, and dry, recycled office air. All you do is apply a quarter-sized amount to your strands and leave it in overnight. I ran it through with my fingers from mid-shaft down to the ends. Then I washed and conditioned like normal in the morning, and while my hair was more shiny and soft, it didn’t feel weighed down.
While this formula is specifically for thick hair, there is a spray-on conditioner for fine hair called Noctogenist Volie Nuit.
