1. Protect your ends.Beauty blogger: Kim Hudnall, 44, @TheHipChickOnline “Dry, split ends make your hair look old, dull, and lifeless,” Hudnall says. To keep hair healthy at its tips between trims, she preps hair with a heat protectant spray like Pureology Color Fanatic ($25, ulta.com) when using hot tools, and relies on the Tangle Teezer ($20, sephora.com) to detangle hair without doing damage. Its bristles are flexible so they’ll bend before your hair snaps. 
  2. Try highlights. Beauty bloggers: Beauty Bookends, Dia Dibble, 50, and Michelle Bouse, 43, @TheBeautyBookends Dyeing your hair a single hue can cover grays but leaves hair flat and lifeless. “Youthful hair naturally has a range of colors,” say Bouse and Dibble. To mimic that, they recommend adding highlights a couple of shades lighter than your base color. Bouse adds auburn highlights to her brunette hair for a sun-kissed effect. Dibble, on the other hand, is a natural redhead and plays with strawberry-blond tones. Bonus: Multitonal hair camouflages gray growth at the root, too, since the line of demarcation isn’t so harsh, Dibble adds. To get the look at home, try a highlighting kit like L’Oreal Superior Preference Glam Lights ($13; ulta.com). MORE: 6 Ways Your Hair Changes After 40—And How To Fix It
  3. Opt for supplements. Beauty blogger: AgeistBeauty, Jonell Copeland, 44, @AgeistBeauty Some research suggests biotin supplements can help make fine hair thicker and healthier, and Copeland’s a believer. “I noticed that as I grew older, my hair was not growing as quickly and seemed to be thinning a bit.” After taking biotin-containing Viviscal Extra Strength hair vitamins  ($31, walmart.com) for two months, “My hair definitely grew longer more quickly,” she says. “Over time, it became thicker and looked healthier, overall.” Good to know: Hair docs warn it’ll take about 4 months before most women see results.

  4. Disguise roots. Beauty bloggers: Beauty Bookends, Dia Dibble, 50, and Michelle Bouse, 43, @TheBeautyBookends “Covering my gray roots makes me look instantly more youthful,” Dibble says. For a quick fix between color appointments, she hides her grays with at-home products like root concealers, hair powders, and hair mascara. Her favorite is Rashell Cosmetics Masc-A-Gray Hair Mascara ($8, rashellcosmetics.com), which has a mascara-type wand that makes application to the grays around her temples less messy than with a spray.

  5. Treat your scalp.Beauty blogger: AgeistBeauty, Jonell Copeland, 44, @AgeistBeauty The skin on your scalp deserves some love, too. Copeland uses Dr. Dennis Gross Skincare Root Resilience Hair Kit ($48, sephora.com). The system, which includes a shampoo, conditioner, and serum, helps support hair follicles with vitamins B and C and antiaging essential oils like grapefruit and peppermint. “When I use it regularly, I notice fewer split ends and fewer strands ending up in my brush,” Copeland says.

  6. Mask lengths.   Beauty blogger: Kim Hudnall, 44, @TheHipChickOnline If you have dry hair like Hudnall’s, consider using a hair mask once a week to give your hair an added boost of moisture. After she tried out the ombré look, her ends were left brittle and parched, so she needed a product to get her hair’s shine back. It’s a 10 Miracle Hair Mask ($30, target.com) did the trick. “I love this one because it’s rich enough to moisturize my hair, leaving it soft and silky without weighing it down or making it feel greasy,” she says, “and even my most ‘fine-haired’ friends agree.”
