When you have to renew dried hair, go after a preshampoo treatment, says Gwen Fields, a beautician and trichologist at Halcyon Salon in Washington, D.C. "These items are stuffed with supporting oils that convey dampness to the hair's fingernail skin and shield helpless strands from extending and snapping when washed," Fields notes. At any rate once week by week, knead the treatment through dry hair, hang out for 15 minutes, then cleanser. Search for one with crucial oils, for example, chamomile (to include sparkle), coconut (to mollify), geranium (to fortify), and argan (to saturate). Attempt Philip Kingsley Elasticizer ($48; philipkingsley.com), which has a combo of regular oils.
