Use a deep conditioning mask.
Treat dry, stressed-out, unmanageable strands with a deep conditioner. Use it once a week—left on for anywhere from 5-15 minutes, depending on the mask and its instructions, it will seriously make hair shine. Try Kerastase Masquintense For Thick Hair ($60 at kerastase-usa.com), which drenches your hair in softness and shine.
Let hair air dry before blowdrying.
Want to cut down on your drying time and actually make hair look better at the same time? Let it air dry first! Give it anywhere from 20-40 minutes after showering so you’re not drying super-soaked strands—and it will actually make your tresses look so shiny you’ll be amazed.
Use a dry shampoo in between washes.
First of all, stop washing your hair every day! Some of the natural oils in your hair actually make it look prettier and shinier! But on those days when you feel like you should wash but just can’t make yourself do it, try a dry shampoo. A little shaken onto the roots and combed through your strands will let you prolong your next washing by at least a day or two.
