In the summer, I tend to leave my naturally curly [read: wavy, frizzy, gross] hair to its own devices. I'll usually throw in some glossing balm and maybe mousse if I'm feeling ambitious. My new go-to product is Umberto's Shimmer Shine Spray.The spray adds shine to the dullest of hair without the added greasiness that often comes with products like this. Shimmer-wise, it's very subtle. No huge chinks of glitter here!
It is a very fine mist of silicone, so it doesn't weigh hair down. If one spray of mist isn't enough, you can always spray again. It doesn't leave hair heavy, coated, sticky, stiff or anything --rather it leaves it shiny, light, and silky.
To use, I spray from the ends of my hair up. Your ends generally lack hydration and are therefore in desperate need of shine. The spray retails at Target for $8.99 for 5 oz., which really lasts a long time. A little definitely goes a long way with this product!
