Trying to grow hair longer or get thicker hair can feel like an endless waiting game. While hair is the fastest-growing tissue in the human body, according to the Trichological Society, the average rate of growth is 0.5 to 1.7 centimeters per month or anywhere from about two to eight inches per year. That growth can feel minimal — especially when you're waiting for it to happen.

Eat the right diet.

Having long, strong hair doesn't just depend on which products you put on your hair; it also depends on what you put into your body. "To promote hair growth, you need to 'feed' the hair from the inside," explains Francesca Fusco, M.D., a dermatologist in NYC. So what foods make hair grow quicker? Those high in protein, the building blocks of hair, including meats and other sources. "Try increasing your protein intake with foods like fish, beans, nuts and whole grains,"

Add a hair-healthy vitamin to your a.m. routine.

If your diet isn't supplying you with enough nutrition, a supplement could make a world of difference. "Look for a multivitamin that's formulated and labeled 'for hair, skin and nails,'" Dr. Fusco suggests. "Those contain important vitamins like biotin and C and B that can support hair health." Good Housekeeping Institute Nutrition Lab deputy director Stefani Sassos suggests these vitamins and minerals to contribute to healthier hair:

  • Vitamin A
  • Vitamin C
  • Vitamin E
  • Zinc
  • Iron
  • Omega-3 fatty acids

4. Shampoo less and hydrate more.

How often you shampoo your hair does actually impact your hair's health. "Shampooing your hair [only] two to three times a week allows your natural oils to penetrate your hair, allowing it to hydrate and repair itself," explains Ken Paves, a celebrity hairstylist in L.A. For thicker and fuller-looking hair fast, choose a shampoo labeled "volumizing" or "thickening."

Lay off the bleach.

As chic as platinum hair looks, going from a darker shade to light blonde could stand between you and your longest-possible hair. "When the cuticle of the hair is damaged from bleach, you can have more breakage or split ends," explains Elizabeth Hiserodt, senior colorist at Cutler Salon in New York City. "The fewer chemical treatments, the better your hair will grow."

6. Avoid excessive heat styling.

"Stop over-styling your hair," says Paves. If you must use heat, he recommends decreasing the temperature and always using a heat protectant — otherwise, you risk damaging your hair, leading to breakage and frizz.

Brush hair regularly.

Going to bed with unbrushed hair may seem tempting when you're tired, but giving your hair a few quick strokes can be great for your hair and scalp's overall health. "Starting at the scalp, use a boar bristle brush to distribute your scalp's oils evenly onto your hair so it stays naturally moisturized," recommends Meri Kate O'Connor, celebrity stylist and colorist at Cooper in West Hollywood, CA. Bonus: This simple step each night also helps increase circulation, which helps make your scalp healthier.

8. Keep your showers cooler and focus on scalp care.

A hot shower can dehydrate your skin — and it's also rough on your hair. "Turn the water temperature down when cleansing," recommends Paves, and give your scalp a little extra love. Massage with your fingers as you shampoo to deeply de-gunk and help boost circulation.

9. Protect hair from physical damage.

Hair is especially susceptible to breakage when it's wet, so instead, detangle hair before shampooing. “Water exposure swells and stretches the hair’s shaft, which causes the shingle-like outer layer to lift, and adding stress from brushing in that state can cause it to break,” says Good Housekeeping Institute Beauty Lab senior chemist Sabina Wizemann.

Sleep on a silk pillowcase.

Getting better hair overnight is possible — all you need is to switch up your pillowcase and reap the hair-healthy benefits of silk. "Silk is easier on hair — it helps avoid tangles and breakage," says Jesleen , M.D., assistant clinical professor of dermatology at Mount Sinai in NYC. The less breakage your hair experiences, the longer your hair will be. In fact, they're so good that the Good Housekeeping Institute even conducted an entire study to find the best silk pillowcases.
