Every once in a while, I look in the mirror and hardly recognize my own hair. In a hot second, it can turn from shiny and manageable to limp and lackluster. This should come as no surprise, really, considering the heat-styling and product-testing I put my tresses through on a near-daily basis.

This time, after I hemmed and hawed and tried the usual suspects — switching shampoos, skipping shampoos, adding more conditioner, getting a trim — without avail, I remembered what I'd stowed in the back of my beauty closet: Frédéric Fekkai Salon Glaze ($28). Applied to damp hair after conditioning, then rinsed out a few minutes later, this at-home treatment imparts the insane shine of a professional glaze. Magically, it feels creamy but never weighs down my long, fine hair, just restores it to its god-given glory. I really should use it on a more regular basis, but something tells me I've been hoarding it so that I'll never have to be without.
