EVERY DAY Eat more protein Hair is made mostly of protein, so up your intake of this macronutrient to at least 46 grams a day, says Francesca Fusco, M.D., dermatologist for Clear Scalp & Hair. (When you eat too little, you run the risk of excess shedding.) The usual sources—eggs, meat, poultry, beans, nuts—work, but a vitamin-packed supplement like Nature’s Bounty Optimal Solutions Hair, Skin & Nails Gummies ($8; drugstores) has targeted ingredients like biotin to stimulate hair growth. For a healthy scalp, add in avocados and fatty fish like salmon: They’re rich in omega-3s that boost scalp circulation, which delivers needed.
ONCE A WEEK Treat with a mask The moisture-stripping cold air and intense winter wind has left your hair brittle. To reverse the abuse, you need deep conditioning. Once a week for the next month, Brook recommends that you apply a mask to damp hair from mid-shaft to the ends. Leave the mask on for at least 10 to 15 minutes so it has time to coat the cuticle with moisture and rebuild the weakened strands. Top picks: John Frieda Frizz Ease Miraculous Recovery Deep Conditioner ($10; drugstores) and It’s a 10 Silk Express Miracle Silk Hair Mask ($35; ulta.com).
ONCE THIS MONTH Make amends with your ends Split ends make strands look damaged and ratty. Before your hair reaches its breaking point (literally!), book a trim. Every two months is generally the rule, using Chanel Rouge Coco; manicure by Julie Kandalec/Bryan Bantry for Chanel le Vernis but post-winter, you should go in every four to six weeks, especially if you had a recent love affair with your heat-styling tools,” says Brook. If you’re trying to grow out your hair, go to the salon for a “dusting,” which means a quarter-inch trim. To nourish ends between appointments, try a split-end mender like Oribe Split End Seal ($46; oribe.com) or Nexxus New York Salon Care Promend Targeted Leave In Crème ($18; drugstores); both contain polymers to temporarily fuse split tips back together.
It’s loaded with strengthening antioxidants like biotin and vitamin E, and protects hair from temps up to 450 degrees. If you can live without your heat tools for a few days, consider the time in between shampoos your opportunity to change up your look. “You can do a half-up style or braid the day after washing, and then a bun or pony the next,” says Brook. One thing to purge completely during a hair detox: alcohol-based hairsprays, which can dry out the hair’s cuticle layer and lead to serious brittleness.
