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. A nutritious diet, budget-friendly home remedies, and over-the-counter products can help reduce the appearance of thinning hair, but it is important to remember that there is no one-size-fits-all solution.
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.
The AAD states that shampoos may help a person retain moisture in their hair, making it appear thicker and fuller. They may also reduce breakage, which may help with thinning. However, hair loss shampoos cannot regrow hiar or prevent hair loss from worsening.
There are several ingredients which might reduce the appearance of thinning:
- Ketoconazole: One
2020 systematic review found some evidence that ketoconazole was helpful for people with androgenetic alopecia, a common type of hair loss. The authors did note that more clinical trials are necessary. - Hyaluronic acid: A 2024 study found some evidence that hyaluronic acid may promote hair growth.
The AAD states that some nutritional deficiencies can cause hair loss, such as biotin, iron, protein, or zinc. Multivitamins or supplements specifically for hair loss often contain these ingredients.
However, it is worth noting that there is not enough evidence that biotin supplementation can increase hair growth in people without this deficiency.
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.

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
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
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
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
A different 2015 study observed that coconut oil can thicken the hair and stimulate its growth.
Learn about using coconut oil for the hair.
Rosemary oil
People can apply rosemary oil directly to their scalp or mix it with their regular shampoo.
An
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
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
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.
