Hair loss prevention and treatment
Research shows that up to half of males and females will experience androgenetic alopecia, or genetic hair loss, in their lifetime.
up to half
In some cases, it may be possible to prevent — or at least slow down — hair loss. However, this will depend on the underlying cause of a person’s hair loss.
hair loss
Some of the best prevention methods are:
eating a balanced diet
using combs with wider spaces between the bristles
avoiding harsh treatments and hairstyles
switching medications to avoid the side effect of hair loss, if possible
avoiding pulling or twisting hair

People may be unable to slow or prevent some types of hair loss. In these cases, males can try active treatment methods.
Medication
Over-the-counter (OTC) medications are available that may help treat hair loss. These include foams and ointments.
The two most common medications are minoxidil (Rogaine) and finasteride (Propecia).
minoxidil (Rogaine)
finasteride (Propecia)
Scientists originally developed minoxidil to treat high blood pressure. The developers found that the medication had the side effect of excessive, unwanted hair growth. This effect gave drug companies a reason to consider it as a treatment for male baldness.
developed
high blood pressure
baldness
Researchers do not know exactly how minoxidil works. The drug appears to widen the hair follicles, which causes thicker strands of hair to grow.
do not know
In addition, minoxidil appears to prolong the growth period of hair, resulting in longer hair and a higher number of hair strands.
Minoxidil is safe and effective when people use it properly. It is more effective in individuals who are under 40 years of age.
is safe
A 2019 review notes that topical minoxidil is approved by the Food and Drug Administration (FDA) only for the treatment of androgenetic alopecia in males and females. However, doctors may recommend off-label minoxidil use for other hair disorders, such as alopecia areata, scarring alopecia, and hair shaft disorders.

alopecia areata
The FDA notes that the term “off-label” refers to approved medications that doctors prescribe for unapproved uses.

Minoxidil can cause some side effects, including:
including
hair shedding
skin irritation and redness
itchy, yellow, or white scales on the scalp
allergic contact dermatitis
excessive hair growth over the body, including on the face in some females
Minoxidil is not suitable for people who are pregnant or nursing or for those who have a hypersensitivity to the medication’s ingredients.
It comes in 5% and 10% strengths.

Rogaine
Price: around $53
Pro: widely studied and recommended
Con: may take 2–4 months to show results
Rogaine is a 5% minoxidil foam for males over the age of 20 years.
According to the makers of Rogaine, the product is suitable for all hair types and is easy to apply.
However, it may take 2–4 months for a person to see results. Additionally, the product may have side effects such as skin irritation, skin scaling, contact dermatitis, and excessive hair growth in other areas of the body.

Finasteride is an FDA-approved treatment for male pattern baldness.
Scientists originally created finasteride to treat prostate cancer. It works by decreasing the amount of the hormone dihydrotestosterone (DHT) in the scalp.
prostate cancer
decreasing
dihydrotestosterone (DHT)
DHT appears to cause hair follicles on the scalp to become thinner, so reducing DHT levels may promote hair regrowth and slow hair loss.
cause
This drug carries several warnings about its use. It is suitable only for adult males and is not suitable for people who are pregnant or nursing.
warnings
Unlike minoxidil, finasteride does not affect hair growth in other parts of the body.
Finasteride is available in both topical and oral forms. A 2020 review states that the topical formulation of this drug is less likely to cause severe side effects than the oral version.

Medical therapies
There are several therapies a healthcare professional may recommend.
PRP is a newer treatment that doctors use for androgenetic alopecia.
PRP
It involves a doctor taking a blood sample and running it through a centrifuge machine. This machine separates the PRP in the blood so the doctor can extract the platelets and inject them into specific areas of a person’s scalp.
The platelets may promote healing in damaged hair follicles.
According to a 2019 review, PRP therapy can reduce hair loss, but the research supporting this is of low quality.
2019 review
This treatment is not FDA-approved.

The only surgery available to address hair loss is hair transplant surgery.
hair transplant surgery
Hair transplantation is for people with male pattern baldness. A hair transplant involves removing hair follicles from the back of the head, where they are resistant to DHT, and placing them on the scalp.
Like any other surgery, hair transplants carry the risk of complications.
The American Society of Plastic Surgeons states that the risks of hair transplant surgery include excessive bleeding and wide scars. Additionally, there is a chance the skin plugs may die, and this requires further surgery to fix.
American Society of Plastic Surgeons
Laser treatment
Laser treatments, such as combs, are a newer form of hair loss treatment. Advocates claim that these devices promote hair growth by using concentrated light to stimulate hair follicles.
Laser comb treatment has mixed results and may work best when combined with other forms of treatment.
A 2019 study found that a novel laser cap improved hair density and diameter, as well as the visual thickness of hair, in 19 participants. However, the authors note several limitations to this study, such as a small sample size.

Over-the-counter therapies
There are several products people can purchase over the counter that may help prevent or slow hair loss.
Therapies for hair loss often involve a combination of drugs, ointments, creams, and shampoos, which a dermatologist may prescribe.

Other therapies involve meeting with specialists.
Several companies specialize in hair treatments for men. They typically offer services to help work out the best course of action and tailor treatments to an individual’s needs.
In some cases, hair loss may be permanent or long term.
Some people might prefer a nonmedical approach to treating hair loss. Wigs and hairpieces offer a means of disguising hair loss.
Wigs and hairpieces have advanced greatly in quality in recent years.
If a medical condition is causing a person’s baldness, their insurance provider may cover the cost of a wig. It is important to check insurance coverage before purchasing a wig.
Essential oils are readily available online and may help promote hair growth.
A 2020 systematic review found that rosemary oil and tea tree oil may help prevent further hair loss.
2020 systematic review
There is some evidence that rosemary oil is as effective as 2% minoxidil. The participants were also more likely to use rosemary oil regularly than minoxidil. However, more research is necessary.
Tea tree oil in combination with minoxidil and diclofenac, an anti-inflammatory drug, may be more effective than minoxidil alone.

Saw palmetto comes from the Serenoa repens tree. It is a natural remedy for conditions such as enlarged prostate, chronic pelvic pain, and migraine. However, there is not enough evidence to suggest that this supplement is more effective than a placebo.
such as
A 2020 systematic review found that saw palmetto may be beneficial for people with hair loss or hair thinning. The researchers looked at seven trials and studies and found a 60% improvement in overall hair quality, a 27% improvement in hair count, and an over 82% increase in hair density.

Additionally, saw palmetto does not appear to have any adverse side effects in people with androgenetic alopecia.

Onion juice may be an alternative remedy that can help stimulate hair growth.
While researchers do not fully understand the mechanism of action behind onion juice and hair growth, it is possible that the sulfur and phenolic compounds stimulate hair growth through irritant contact dermatitis.
In fact, a small study of 64 people with androgenetic alopecia found that 87% experienced full hair regrowth compared with 13% using simple tap water.
small study
The most common side effect of using onion juice is experiencing an unpleasant smell.
Lifestyle changes
There are several lifestyle changes a person can make to prevent hair loss or stop hair from thinning even more.
A 2022 review suggests that smoking may lead to hair loss. Smoking may constrict the blood vessels, cause free radical damage to hair follicles, and change the effect of hormones on the body. However, the researchers conclude that there is not enough evidence to suggest that quitting smoking can reverse the damage.
2022 review
There is some evidence that people who smoke larger quantities of cigarettes per day are at greater risk of hair loss, although this is not conclusive. It is also possible that smoking increases the chance of prematurely graying hair.
some evidence
Quitting smoking can be difficult, but there are several therapies available that can help. People may wish to use nicotine replacement therapy, use smartphone apps, or quit cold turkey. Healthcare professionals can advise people on the benefits and drawbacks of each therapy.

Scalp massage is a free technique that may help stabilize hair loss.
A survey of 340 people across a range of ages, genders, and severities of hair loss found that scalp massage can increase a person’s perception of hair growth.
survey
The respondents spent an average of 36.3 hours massaging their scalps over a period of around 6 months. Over 68% of respondents self-reported hair loss stabilization or hair growth. The results did not vary across demographics, suggesting that scalp massage may be beneficial for all people who are concerned about hair loss.
However, the researchers note that respondents were less likely to perceive improvements in hair loss if they experienced all-over hair thinning, rather than thinning on a specific area of the scalp.
Following a healthy diet can help people live longer and reduces the risk of certain conditions such as type 2 diabetes.
type 2 diabetes
Some vitamins and minerals may contribute to hair loss, either from consuming too much or too little.
A 2019 review suggests that the following nutrients may play a role in hair loss:
2019 review
Vitamin A: Consuming too much vitamin A, either through diet or supplementation, can lead to hair loss. This is because the liver cannot adequately regulate vitamin A levels in the body if a person consumes too much, which then leads to the vitamin spilling over into the circulatory system.
Vitamin A
Vitamin B: Vitamins B2, B7, B12, and folate can cause hair loss if a person does not consume enough. Vitamin B2 deficiency is rare in the United States, and people can find sources of other B vitamins in proteins or supplements.
Vitamin B
Vitamin D: Vitamin D deficiency may lead to hair loss. There is evidence that people with androgenetic alopecia have lower levels of vitamin D than people without this condition, suggesting that the vitamin plays a role in hair retention and thickness.
Vitamin D
Iron: Iron deficiency is common in females with hair loss. There is some evidence that iron may help regulate the genes that contribute to hair growth.
Iron
Selenium: Selenium deficiency can lead to a loss of pigmentation and hair growth. However, most people receive adequate selenium levels through their diet, as this nutrient is in a variety of foods, including meat, vegetables, and nuts.
Selenium
Zinc: There is some evidence that low levels of zinc may contribute to androgenetic alopecia. However, more research is necessary to investigate the link between zinc and hair loss.

Causes of hair loss in men
Men can experience baldness or hair loss for several reasons.
The most likely cause is genetics. Finding out whether hair loss is due to genetics or another factor can help a doctor determine the best course of treatment.
most likely
Male pattern baldness is a hereditary condition and the most common cause of male baldness. It can start as early as puberty or develop much later in life. It often occurs gradually and in predictable patterns, affecting the temples and the front of the middle of the scalp.
Male pattern baldness
puberty
Most often, males will be left with a horseshoe pattern of hair. Heredity affects how fast, at what age, and to what extent someone will experience baldness.
People with male pattern baldness inherit hair that is more sensitive to DHT, the hormone that can shorten the life span of individual hair follicles.
Other common causes of hair loss in men include:
include
Scalp infections: Infections such as ringworm can affect the hair and skin of the scalp, leading to scaly patches and hair loss.
ringworm
Hormonal changes: Hormonal changes and imbalances can cause temporary hair loss. For men, the thyroid gland is the most likely cause of hair loss due to hormonal changes.
Patchy hair loss: Patchy hair loss, also known as alopecia areata, occurs when the body’s immune system attacks hair follicles. The attack causes sudden and rapid hair loss that leaves smooth, often round bald patches on the skin.
Skin disorders: Diseases such as eczema, severe seborrheic dermatitis, psoriasis, and lupus may result in permanent hair loss in the scarred areas.
seborrheic dermatitis
psoriasis
lupus
Hair-pulling disorder: This disorder, called trichotillomania, causes people to have an irresistible urge to pull out their hair. A person will pull hair from the scalp, the eyebrows, or other areas of the body.
trichotillomania
Medication: Hair loss may be a side effect of certain medications.
Some less common causes of hair loss are:
are
Radiation treatment: If a man receives any sort of radiation treatment near the scalp, the hair may fall out and grow back differently.
Some hairstyles or treatments: Wearing hair in ways that pull it excessively or treating it with oils or coloring agents can cause permanent hair loss.
Natural triggers: Stress, childbirth, fever, surgery, or extreme trauma may lead to loss of hair. Often, the thinning will reverse when the triggering event is over.
Stress
childbirth
Coping with hair loss
The emotional impact of hair loss will vary greatly from person to person.
Some people may wish to seek counseling services as part of their treatment. Others may choose a hairstyle that embraces hair loss, such as a shaved head.
Hair loss may affect a person’s self-esteem and lead to depression, anxiety, and reduced quality of life.

Frequently asked questions about male hair loss treatment
There is evidence that treatments such as minoxidil and finasteride can reduce the amount of hair a person loses. However, results may vary from person to person.
People may not see results until they have been using a hair loss treatment for several months. A person should work with a healthcare professional to find a treatment that suits their situation.

People may not see results until they have been using a hair loss treatment for several months. A person should work with a healthcare professional to find a treatment that suits their situation.
Whether a person’s hair grows back depends on the type of hair loss a person experiences.
For example, most people who lose their hair as a result of cancer treatment, such as chemotherapy or radiation therapy, will experience hair growth after their treatment ends.
However, other causes of hair loss, such as male pattern baldness, are typically permanent. Doctors may prescribe or recommend certain treatments to help prevent further thinning of the hair.
If a person experiences hair loss as a result of scarring, the hair is less likely to grow back. It is important for a person to seek advice and treatment from a dermatologist as soon as they notice hair loss. Early intervention can help prevent scarring hair loss from spreading.

Summary
Hair loss has many possible causes, including genetics and disorders of the skin or scalp. While it is not always possible to prevent hair loss, people may be able to slow or stop hair loss by taking a medication such as minoxidil or finasteride or by using OTC products such as laser combs.
People should contact a healthcare professional if they are worried about their hair loss or if the hair loss is sudden. A doctor may order several tests and ask questions to find out the cause of the hair loss.
