While there is no way to change the texture of the hair follicles, there are many ways to help make the hair appear thicker and reduce breakage and hair loss, such as eating a nutritious diet and scalp massage.

Thin or thinning hair is common and can affect anyone. Aging, stress, chemical allergies, health conditions, and nutrition choices are just some factors that may contribute.

This article lists several ways to make hair look and feel thicker that a person can try at home. It also describes products that may help, such as shampoos and supplements.

Hair loss can develop differently, depending on a person’s sex.

According to the British Association of Dermatologists, female pattern hair loss may start later than male pattern hair loss, which could affect men at any age. While it is typical for female pattern hair loss to start when a person is in their 50s or 60s, it can also occur in people ages 30 years or older.

People experiencing female pattern hair loss may notice thinning hair, especially on top of the scalp and the middle parting line. The hairline at the front of the scalp usually remains the same.

People with male pattern hair loss may notice thinning hair on the crown of the head and a receding hairline.

According to the American Academy of Dermatology (AAD), not all types of hair loss are treatable. However, there are ways to help prevent further hair loss or slow its progression.

Research from 2021Trusted Source describes the importance of counseling for people experiencing hair loss.

Many brands sell supplements and shampoos to help stimulate hair growth and thickness.

It is a good idea for people to seek medical advice before introducing a new product as some supplements and shampoos can interact with medications.

Please note that the writer of this article has not tried these products. All information presented is purely research-based and correct at the time of publication.

We selected these hair-thickening supplements and shampoos based on criteria we think are good indicators of safety, quality, and transparency.

As a part of our vetting process, we consider:

  • the product’s composition, ingredients, and overall quality
  • any third-party certifications
  • the company’s reputation and business practices
  • any lab test results
  • marketing claims

A person might try home care strategies, but these should not replace professional treatment for an underlying health condition, such as a nutritional deficiency or alopecia, that may be causing thin hair.

While many people claim these natural remedies may help thicken hair, it is important to note that there is a lack of sufficient research supporting their use on hair.

Eggs

Eggs are rich in protein, which is essential for the production of healthy hair. Some people may consume more eggs to increase their protein intake or try a topical egg treatment once or twice a week for several weeks.

To use an egg treatment:

  • Beat 1 or 2 eggs together.
  • Apply the mixture to the scalp and damp hair.
  • Leave it on the scalp for about 30 minutes.
  • Wash the hair thoroughly with warm water and mild shampoo.

Alternately, combine the eggs with oil and water. To try this method:

  • Mix egg yolks, 1 tablespoon (tbsp) olive oil, and 2 tbsp of water.
  • Apply the mixture to the scalp and dry hair.
  • Leave it on for 15 minutes.
  • Wash it out with warm water and a mild shampoo.

Olive oil

Olive oil is rich in omega-3 acids and other nutrients that are essential for overall health, including hair health. When applied directly, olive oil may soften the hair and moisturize any dry areas of the scalp. While some people suggest olive oil may also stimulate hair growth, such as in this older 2015 study on miceTrusted Source, more research is necessary to understand whether olive oil can promote hair growth in humans.

To use olive oil:

  • Heat the oil to body temperature.
  • Massage the warm oil into the scalp and hair.
  • Leave it on for about 30 to 45 minutes.
  • Wash it out with a mild shampoo.

Some people add honey to the olive oil. Others recommend leaving the oil on overnight while wearing a shower cap.

Proper nutrition

A nutritious diet that contains healthy fats, protein, and a range of vitamins can help thickenTrusted Source thinning or thin hair. In fact, thin hair can be a sign that a person is not getting enough nutrients.

Anyone with thin hair might consider incorporating some of the following nutrient-rich foods into their diet:

  • salmon, which is rich in protein and fatty acids
  • eggs, which contain protein, omega-3s, and iron
  • walnuts, almonds, and other nuts, which are sources of fatty acids
  • Greek yogurt, which is a source of protein
  • green, black, pinto, or other beans, which contain protein

A person might add 1 or 2 servings of any of these foods to their diet every day.

Orange puree

Vitamin C, pectin, and acid in oranges may help the hair in a few different ways.

The vitamins and nutrients may improve the hair’s natural sheen, which may make it appear thicker.

The acid may help break apart residue from hair products that may interfere with hair growth. Unlike some of the other treatments, orange puree also has a pleasant scent.

Although experts typically associate vitamin C deficiency with body hair irregularities, there is no data correlating vitamin C levels and hair loss. Vitamin C may help with anemia, which, if deficient, contributes to hair loss.

To make the puree:

  • Blend fresh oranges.
  • Massage the mixture into the hair and scalp.
  • Leave it on for about 1 hour.
  • Wash it out with a mild shampoo.

A person might use a light conditioner to rehydrate their hair after this treatment.

Aloe gel or oil

The aloe vera plant may have various health benefits for the skin, scalp, and hair.

Aloe vera gel contains vitamin B12 and folic acid. Both of these components may keep hair from falling out. However, there are no studies that confirm conclusively that aloe vera has any benefit in preventing hair loss.

Applying aloe oil directly to the hair and scalp may help strengthen the hair and thicken it over time. Several commercial treatments, including gels and creams, contain aloe as an active ingredient.

For a homemade treatment, try rubbing some pure aloe gel into the hair and scalp and letting it sit for 30 minutes before washing it out. Some people mix the aloe with coconut oil or olive oil.

A person might use this treatment once or twice a week.

Avocado

Avocado is rich in vitamin E, and many people believe it to be a good moisturizer. While there is a lack of evidence to support the use of topical avocado, a person might like to apply a simple avocado hair rub twice a week.

To make an avocado rub:

  • Combine the fruit of 1 avocado with 1 tbsp olive oil.
  • Apply the mixture to the hair and scalp.
  • Let it sit for about 30 minutes.
  • Wash thoroughly with mild shampoo.

Castor oil

Castor oil is also rich in vitamin E and fatty acids, which may support hair health. While there is weaker evidenceTrusted Source for castor oil improving hair quality by increasing hair luster, there is a lack of strong evidence for its use for hair.

A person can rub the oil over the scalp and hair until coated and leave for about 30 minutes before washing it out.

Coconut oil

An older 2015 reviewTrusted Source found that hair strands can absorb coconut oil and that the oil prevents breakage and split ends.

A different 2015 study observed that coconut oil can thicken the hair and stimulate its growth.

Rosemary oil

People can apply rosemary oil directly to their scalp or mix it with their regular shampoo.

An older 2015 trialTrusted Source looked at the effects of rosemary oil and minoxidil (Rogaine) in people with androgenetic alopecia. It found that rosemary oil was equally effective as the medication at reducing scalp itchiness.

The AAD explains that thin hair is fragile and has an increased risk of damage. The association provides these tips for people with hair loss:

  • using a gentle shampoo that does not remove moisture
  • using a moisturizing conditioner to reduce breakage and split ends
  • applying a leave-in conditioner after washing and conditioning to prevent frizz and breakage
  • wrapping the hair in a microfiber towel before blow-drying it

The AAD also warns against using curling or flat irons, as these can weaken the hair. A person might also reconsider other styling options. For example, pulling the hair back in a ponytail or bun can lead to permanent hair loss over time.

Scalp massage

A 2016 studyTrusted Source showed that massaging the scalp can help thicken the hair. It found that a 24-week massage treatment increased hair thickness.

Also known as micro-rolling, this involves shaving the scalp and pricking it with tiny, sterilized needles in a handheld tool.

Microneedling may stimulate the hair follicles. An older 2013 studyTrusted Source shows that in combination with topical minoxidil, it may help with regrowth, fullness, and thickness.

The University of Michigan Health System mentions two medications that can help slow hair thinning and thicken hair shafts:

  • Minoxidil (Rogaine): Versions marketed for men and women are available without a prescription, and a person can spray or rub it into their scalp twice a day. However, this drug does not cure baldness, and overusing it does not cause the hair to grow faster. Once a person stops using this product, they may lose the new hair within a few months. Learn more about Rogaine.
  • Finasteride (Propecia): This prescription treatment involves taking a daily pill, but it is not suitable for females. Learn more about finasteride.

The university’s health system warns that it may take 1 year to start seeing results from these medications and that most private insurance plans do not cover the costs.

Cold caps

Cancer treatments such as chemotherapy, immunotherapy, and radiation therapy can cause hair thinning or loss.

Anyone looking to prevent this might try a cold cap, a hat-like garment designed to protect the hair follicles from the effects of chemotherapy.

Many companies manufacture cold caps, including Penguin Cold Caps and Arctic Cold Caps.

Below are some common questions about hair thickening.

A person can make a hair treatment to increase hair thickness from everyday products, such as eggs, olive oil, and avocados. The results may vary from person to person.

Some companies also market products to people and promise to make the hair appear thicker and fuller. These may also help slow hair loss. The AAD reports that some shampoos can lock in moisture and reduce breakage, preventing hair thinning.

Anyone who suspects they have hair loss could consult a dermatologist, who can identify the cause of thinning or shedding hair and recommend the proper treatment. The doctor may prescribe minoxidil, a drug that can stimulate hair growth and slow balding.

Not all hair loss types will have a cure, but a trained professional may be able to slow the progression of hair loss or prevent further loss.

There are several reasons why someone may have thin or thinning hair, such as genetics, stress, illnesses, medications, and more. Styling the hair in certain ways can also lead to hair loss over time.

A person cannot change the texture of their hair. However, the hair may grow back after chemotherapy or pregnancy, for example.

 

Anecdotal evidence suggests that various everyday ingredients, such as coconut oil, can help thicken and strengthen the hair. It is important to note that very little scientific evidence, if any, supports these treatments, and the effects may vary from person to person.

It is also crucial to avoid any known allergens.

Anyone with sudden or unexplained hair loss or thinning should receive medical attention, as a health condition may be the cause.

Natural home remedies may be low cost and low risk. In some cases, a person may prefer a commercial product designed to treat or help prevent hair loss.
