Eating more protein and following a Mediterranean diet may lower the risk of hair loss.

A 2017 study found that several participants experiencing hair loss had low protein and amino acid intakes. Researchers need to carry out additional studies to examine whether nutritional deficiencies do relate to hair loss.

Studies dating back several years suggest vitamins help prevent hair loss.

A review in Dermatology and Therapy examined the role of various vitamins and minerals in preventing hair loss. The role of vitamins and minerals in hair loss remains unclear.

However, vitamin deficiencies may be a risk factor for hair loss. Some vitamins and minerals that may help include:

Anyone considering taking a multivitamin supplement should talk to a doctor first. The best products contain all or most of the recommended daily amounts of each vitamin and mineral in a single dose.

A 2017 study in Archives of Dermatological Research found an association between the herbs and vegetables in the Mediterranean diet and a decreased risk of androgenetic alopecia, or pattern baldness, in males.

A small study in 9 healthy men found that a daily 4-minute scalp massage stimulated hair growth.

These findings are promising. But researchers will need to study larger samples to determine whether scalp massages are helpful for hair loss.

A study in 2018 found that coconut oil may help to prevent hair loss due to ultraviolet light damage or grooming habits. However, further research is necessary to confirm this.

Applying coconut oil to the scalp could strengthen hair and avoid loss from damage.

Several topical medications for preventing hair loss are available over the counter (OTC).

According to a 2019 review of studies, minoxidil is the go-to treatment for androgenetic alopecia in both men and women. Minoxidil is the active ingredient in Rogaine.

The review suggests that doctors sometimes use minoxidil for treating other causes of hair loss, such as from chemotherapy. The authors of the review state that more research into minoxidil could be beneficial.

Finasteride is another medication for hair loss on the scalp.

A study in the Indian Journal of Dermatology found that finasteride was effective for regrowing scalp hair. However, finasteride did not cause hair to regrow in other areas of the body.

According to a 2014 study, low-level laser light therapy (LLLT) can increase hair density. This applies to people with chemotherapy-related or genetic hair loss.

Further research is necessary to determine the proper wavelengths and duration of treatment.

Taking proper care of the hair and scalp can help prevent hair loss. It may also improve hair growth. Keeping the scalp and hair clean may also prevent hair damage and loss.

According to a 2015 review, certain medicated shampoos and conditioners could prevent hair loss. Avoiding harsh treatments, such as heat, curling, and dyes, may also help.

Onion juice may have a positive effect on hair loss. In a small, older study, researchers found that applying onion juice to the scalp helped hair regrowth in both men and women with patchy alopecia.

About 80% of participants using onion juice saw improvements after 6 weeks.

Hair grows and eventually falls out as part of its normal cycle. It can build up on hair brushes, pillows, or shower drains.

Most people will not notice the natural hair loss that occurs daily. Hair thickness and the hairline usually remain the same.

People are more likely to notice excessive hair loss. This is a good time to take action as it may be due to an underlying condition. Symptoms of excessive hair loss include:

  • sudden loss of hair
  • losing patches of hair
  • noticeable thinning

There are several possible reasons for excessive hair loss.

One of the most common causes is due to genetics. According to a 2019 review, pattern baldness affects up to 50% of men and women.

Commercial products could help to slow and treat this type of balding. One example of these products is Rogaine.

Pattern baldness occurs slowly with aging. Some more immediate causes of hair loss include:

Hair loss is a common occurrence, particularly from pattern baldness.

People looking for a treatment to help prevent or regrow hair have several potential options. The effectiveness of each option will vary from person to person.

People should talk to a doctor before starting a new hair loss treatment or taking supplements.
