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.

It’s normal to shed between 50 and 100 hairs a day, according to the American Academy of Dermatology Association (AAD), but if you think your growth is really stunted, there are certain tweaks you can make to your day-to-day haircare regimen to boost hair growth. You can try using a different hair brush, adjusting how often you use your hair dryer to dial down damage to your hair or adding in hair growth oils and foods to make hair grow quicker to your routine.

These are the secrets and home remedies that grow hair fast, according to top dermatologists, celebrity hairstylists, skincare experts and our own Good Housekeeping Institute Beauty Lab pros.

1. Get frequent trims.

It may seem counterintuitive, but if you want long hair that’s actually healthy, you need to get regular trims. “While haircuts don’t make your hair grow any faster, they get rid of split ends that break your hair,” explains Michael Dueñas, a celebrity hairstylist based in Los Angeles. “Eliminating the breakage gives the appearance that your hair is growing faster.” After all, a split end that breaks can lead to your hair losing length — not to mention shine, volume and smoothness.

2. 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,” she recommends. Even if you’re not a meat lover, you should still aim to maintain a diet high in protein for hair growth. Women who don’t get enough of it often experience “more hair shedding,” Dr. Fusco says.

And steer clear of trendy “cleanses” for a multitude of reasons. “Doing a cleanse is terrible for your hair because you’re depriving your body of nutrients,” Dueñas warns. “After doing a cleanse even for a week, you’ll notice slower hair growth and lackluster locks.”

3. 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.”

Coating your strands in a silky deep conditioner or hair mask or a hair detangler regularly can also help to prevent damage while detangling strands, according to GH Beauty Lab pros. Slather on a store-bought or DIY hair mask from root to tip once a week: One with cinnamon can stimulate blood circulation to encourage stronger, longer hair in no time, says Liana Zingarino, a freelance hair stylist based in New York City.

5. 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.

7. 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.

If you have to detangle hair when wet, do it the right way: Apply a top-rated leave-in conditioner from roots to ends and use a gentler wide-tooth comb or detangling brush to reduce friction, working from the ends up in small sections to prevent tearing hair, Wizemann advises.

10. 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 Ahluwalia, 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.

11. Try using minoxidil.

Pick up a bottle of Women’s Rogaine, recommends GH beauty director April Franzino. “The active ingredient, minoxidil, is FDA-approved and proven to help stop hair loss and promote hair regrowth with continued use according to packaging instructions.” For a more targeted solution, pick up Hers 2% Minoxidil Topical Solution and use the dropper applicator to focus on more specific problem areas.

But be wary of shampoos that claim to grow hair — hair growth from shampoo “has yet to be scientifically proven, at least in published research or to FDA’s standards,” says Jeni Thomas, Ph.D., principal scientist at Proctor & Gamble Beauty.

When to talk to your doctor about hair loss

Underlying causes of hair loss may be contributing to your hair’s slow (or lack of) growth. It’s estimated that more than 50% of women will experience noticeable hair loss, according to Cleveland Clinic — and that doesn’t count those born with wispy or sparse strands. “Hair that’s naturally thin in diameter [fine] or sparse is genetic,” says Joyce Davis, M.D., dermatologist in NYC. “Hair loss is often hereditary (or androgenic) thinning, which tends to be patchy.” Another common type of hair loss is telogen effluvium (TE), or allover shedding due to hormones or health issues such as thyroid or autoimmune disease and anemia.

With TE, hair generally grows back once the problem is treated; see a doctor for diagnosis. For androgenic loss, the over-the-counter topical minoxidil mentioned above is proven to grow hair with continued use. For all types, the professional treatment PRP (platelet-rich plasma) stimulates growth with scalp injections of your blood’s growth factors, Dr. Davis says. Consult a dermatologist to find out if it’s right for you.

Almost everyone has some hair damage, from dryness and brittleness to split ends and breakage. The best way to tackle dry and damaged hair really depends on the cause and type of damage. Find the best fix for your hair with these pro tips on prevention and solutions from the

Good Housekeeping Institute Beauty Lab experts and hair specialists.

Can you actually repair damaged hair?

“Once hair is split or broken, nothing can permanently fuse it back together,” explains Beauty Lab executive director Birnur Aral, Ph.D. “Products like split-end menders, leave-in conditioners and treatment masks can seal the outer layer of strands so they temporarily appear smoother and less frayed and feel softer, and help protect hair from further damage.” However, the only real long-term solution is by cutting your hair, to trim off damaged areas.

That said, conditioner is damaged hair’s best friend: Damaged hair is stripped of its protective outer layer, and conditioner helps replenish it with emollient ingredients like silicones and plant oils (such as coconut oil) and butters. “They coat wet hair so it’s easier to detangle, which can lead to less damage and make it silkier and more manageable,” Aral says.

For maximum benefits to prevent damage, use a rinse-off conditioner after every shampoo, plus a leave-in conditioner on damp hair. Swap in a deep conditioner or hair mask weekly: “These tend to contain higher concentrations of conditioning ingredients, making them thicker and heavier,” Aral explains.

How to repair chemically damaged hair

When using hair color, chemicals such as ammonia have to be used to open your hair shaft, so the dye can be deposited. Ammonia-free formulas exist, but industry studies have found that they’re just as harmful (you have to use more and leave them on longer).

Your hair is damaged if after showering, your hair dries almost instantly. That shows just how porous those color chemicals have made it, says Katherine Polite, a colorist at Zano Salon in Chicago.

1. Use a moisture-rich hair dye

Many dyes, like the Beauty Lab’s recommended formulas below, are infused with conditioning ingredients to help protect and repair hair during the color process. For gray coverage, go with a semi- or demi-permanent formula — it’ll fade faster but is less harsh than a permanent dye. To highlight at home, avoid pull-through caps, which often result in damaging color overlap (go for a cap-less kit instead).

2. Only dye your roots

When possible, reapply dye to just the roots to minimize chemical exposure on the lengths, and “space dyeing hair 10 to 12 weeks apart at minimum,” says George Papanikolas, Matrix celebrity colorist in Los Angeles. Finally, major color changes can cause major harm (including hair breakage or even loss) when done wrong, so leave those to the pros.

How to repair broken hair and flyaways

The wrong tool or the wrong technique can tangle or, worse, tear your hair. You’re in trouble when you look in a mirror and see tiny hairs sticking up along your part and hairline. These aren’t “baby hairs” growing in, says Cheri McMaster, senior scientist for Pantene: they’re hairs that have broken. Here’s how to to stop that breakage in its tracks:

3. Invest in a good brush to prevent breakage

Bristles are the key to preventing breakage. They should be soft, smooth — avoid those with plastic balls on the ends — and spaced out, as on a comb. Wet Brush is designed specifically for wet hair: its thin, perfectly-spaced IntelliFlex bristles are flexible and specially designed to be firm enough to get through knots and tangles, yet soft enough to keep hair healthy and snag-free.

4. Don’t brush wet hair

H2O can exacerbate the issue: “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,” explains GH Beauty Lab senior chemist Sabina Wizemann.

Brush your hair before washing if possible, and if you have to detangle it wet, towel-dry so it no longer drips, apply a leave-in conditioner from roots to ends, and use a gentler wide-tooth comb or detangling brush to reduce friction. Work from the ends up in small sections to avoid ripping strands, she suggests.

How to repair damaged hair from heat

Blow-drying, flat-ironing and curling can all cause hair’s outer layer to lift up, releasing valuable moisture and leaving strands brittle, dry, and damaged. To tell if your hair is damaged, pull out a hair, run your fingernail from root to end (as if curling a ribbon), drop the strand into a glass of water — and see if it uncurls. If it doesn’t, your hair has lost elasticity, McMaster says.

5. Use heat protectant

Before drying or ironing your hair, McMaster says, use a heat protection hair spray or serum that contains silicones or polymers, which create a protective barrier over strands. “These stylers work by coating hair at the high temperatures of heat styling and shielding the surface of damaged strands, which can improve hair’s manageability, in turn resulting in reduced breakage,” Aral explains.

6. Make sure hair is dry before styling

Most importantly, “never blow-dry hair that hasn’t been towel- or air-dried partially first or use styling irons on hair that’s not totally dry, as that can cause any water inside to boil and the strand to rupture,” Wizemann warns. To avoid harmful friction, dry hair by wrapping your head in a small microfiber towel for a few minutes.

7. Replace old heat tools

Throw out any heat-styling tool that you’ve had for more than five years: The older the appliance, the higher the chance that the temperature gauge has gone kaput, says Beverly Hills celebrity stylist Cristophe. Use your blow-dryer’s nozzle attachment; it cuts down on cuticle ruffling.

Pick a flat iron that has ceramic plates: Since ceramic heats up evenly, it straightens hair faster and won’t stick to — or singe — any one spot.

How to repair environmental hair damage

Sun, water, chlorine — a day of fun outdoors can be hard on your hair. These essentials will help.

8. Shield hair from the sun

Cover hair with a hat to help shield it from the sun, which can damage hair at high levels of exposure, the Beauty Lab says. A tightly-woven hat can also help prevent sun burns and skin cancer on your scalp. (Bonus points if it has UPF protection, like the one below, which certifies that its fabric weave block’s UV rays.)

9. Coat hair in a “waterproofing” product

Before swimming, wet your hair with shower or tap water, then coat it with a leave-in or regular conditioner to form a barrier against the chemicals like chlorine in pool water, which can cause color stripping and breakage, Cristophe says. Plus, dousing hair in clean water means it can’t absorb as much chlorine to begin with.
