How to Grow Hair Faster:
What Helps, What Does Not

How Fast Does Men's Hair Actually Grow?

Scalp hair grows about 1.0 to 1.3 cm a month, a little under half an inch, from roughly 100,000 follicles. Each hair keeps growing for about two to six years before it rests and falls out, and at any given moment around 80 to 90 percent of follicles are in that growth phase. These figures come from the sources collected in our hair growth statistics report.

Rates vary a lot between people. In one British Journal of Dermatology study, white European volunteers averaged about 396 micrometers a day and African volunteers about 256 micrometers a day, under 1 cm a month, with wide individual ranges in both groups. Curly and coily hair also looks shorter than its true length because of shrinkage, so visible length can lag behind actual growth. The table below shows how long it takes to add length at typical rates.

What Actually Affects How Fast Hair Grows?

Most of what sets your growth rate is outside your control. Genetics decides how fast your follicles produce hair and how long each strand stays in its growth phase, which is why some men can grow hair to their shoulders and others find it seems to stop at a certain length. Age matters too: growth tends to slow and strands get finer as people get older. The factors below can slow growth or increase shedding, and some of them can be addressed.

It helps to separate two different complaints. One is hair that grows at a normal pace but never seems to get long, which is usually breakage or a short natural growth phase. The other is hair that sheds more, thins out or grows back finer than before, which points to something happening at the follicle. The first is mostly about care and patience. The second deserves a medical opinion, because the cause decides what will help and what is a waste of money.

Genetics and hormones

Inherited sensitivity to male hormones drives pattern hair loss, where follicles on the crown and hairline gradually produce shorter, finer hairs. That is a medical topic, not a styling one; a doctor or dermatologist can explain the options.

Illness, surgery and major stress

A shock to the body can push many hairs into the resting phase at once, with shedding showing up weeks or months later. This kind of shedding often settles over several months, but it is worth having a doctor confirm the cause.

Diet and deficiencies

Very low calorie diets and some nutrient deficiencies are linked with hair shedding. A doctor can check whether anything is low with a simple blood test; guessing with supplements is not the same thing.

Medications and health conditions

Some medicines and conditions, including thyroid problems, can affect hair. Do not stop any prescribed medication on your own; raise the question with whoever prescribed it.

Does Cutting Your Hair Make It Grow Faster?

No. Hair grows from the follicle below the skin, and cutting the ends has no effect on that. The American Academy of Dermatology lists faster growth from frequent haircuts as a popular myth. What trims do is remove split ends before the split travels up the strand, which keeps the ends looking thicker and stops you losing more length to breakage later. That is why barbers still recommend small trims while you grow your hair out.

The practical approach is to trim less, not more. While you grow out the top, ask for a dusting of the ends every eight to twelve weeks, and keep the sides and neckline tidy more often if you want the cut to look deliberate. Our guide on how to grow your hair out covers the stages, styles and barber requests for each length, so this page focuses on growth itself.

How Can You Keep More of the Length You Grow?

If hair breaks at the ends as fast as it grows at the roots, length seems to stall even though growth is normal. This is the part you can influence most. Long, dry or chemically treated hair is the most at risk, and men moving from short cuts to longer ones often keep the same rough habits that worked when hair was an inch long. Small changes to washing, drying and styling make a real difference over six months.

Track progress the simple way. Take a photo of the same angle in the same light once a month, or measure a strand at the back of the head with a ruler. Checking the mirror every morning makes growth feel slower than it is, because a third of a millimeter a day is invisible. If the monthly photos show steady length but the ends look thin and see-through, focus on breakage. If length is fine but density is dropping, talk to a doctor.

Handle wet hair gently

Wet hair stretches and snaps more easily. Squeeze it with a towel instead of rubbing, and detangle with a wide-tooth comb from the ends upward.

Use less heat

Let hair air-dry most of the way before using a dryer, keep it on medium heat and avoid flat irons on a regular basis.

Go easy on chemical treatments

Bleaching and perms weaken the strand. If you want to color while growing out, space treatments well apart and see how to bleach hair safely first.

Avoid constant tension

Tight buns, ponytails and braids worn in the same spot every day can pull on the follicles over time. Change the position and loosen the tie.

Condition the lengths

A conditioner on the mid-lengths and ends after every wash reduces friction and tangles. Dry, damaged ends recover best with the approach in our damaged hair recovery guide.

Do Supplements, Oils or Scalp Massage Speed Up Growth?

The evidence is thinner than the marketing. Vitamins and minerals matter if you are actually short of them, but there is little good evidence that extra biotin, zinc or multivitamins make normal hair grow faster in people who are not deficient. Hair restoration doctors are cautious too: in the ISHRS 2025 Practice Census, which covers 2024, about half of member physicians said they rarely or never prescribed biotin, as our hair growth statistics report notes. High-dose biotin can also interfere with some blood test results, so tell your doctor if you take it.

Scalp massage has been studied in small trials, and some men find it relaxing, but it is not a proven way to change growth speed. Oils such as rosemary or castor oil are popular online; the research behind them is limited, and they can irritate sensitive skin or clog an oily scalp. Minoxidil and prescription treatments are medical decisions with benefits and side effects that vary from person to person. Discuss any of them with a doctor or dermatologist before starting.

When Is Slow Growth Really Hair Loss?

Sometimes hair that seems slow to grow is actually thinning. Signs include a hairline that is moving back at the temples, a crown where the scalp shows more under bright light, hair that grows in finer than before, or a ponytail that is getting thinner. Shedding of roughly 50 to 100 hairs a day is normal, but sudden clumps, patches of smooth skin, itching, redness or scaling are reasons to see a doctor rather than try another product.

Seeing a doctor early does not commit you to any treatment. It gives you a diagnosis, which makes every other decision easier, from which haircut to wear to whether a treatment is worth trying. In the meantime, cuts that work with thinner density, such as those in haircuts for thinning hair on top, can make the most of the hair you have. Our male hair loss statistics page shows how common this is.

What Daily Habits Support Healthy Hair Growth?

None of these habits will double your growth rate, but they support normal growth and reduce the shedding and breakage that make hair look slow. Eat a varied diet with enough protein, since hair is made mostly of protein. Sleep and manage stress where you can, because major stress is one of the known triggers for shedding. Keep the scalp clean without over-washing; a calm, flake-free scalp is a better base for hair than one coated in old product.

Smoking is linked with earlier hair loss in several studies, so cutting back helps hair as well as everything else. Protect long hair from sun and chlorine the same way you would protect skin, by rinsing after swimming and wearing a hat in strong sun. For a simple weekly routine, see scalp care basics. Then give it time: changes to growth habits take months to show, because the hair you see today began growing long ago.
