Supplements for Hair Loss: Do They Really Work?

Supplements for Hair Loss

Hair loss is a common problem that affects both men and women. It can be caused by a variety of factors, such as genetics, age, hormonal changes, stress, and poor nutrition. While there are many treatments available for hair loss, including medications, hair transplants, and topical solutions, some people turn to supplements as a natural alternative. But do supplements for hair loss really work? In this article, we’ll take a closer look at the effectiveness of supplements for hair loss, which ones are worth considering, and what you can expect from them.

What are Supplements for Hair Loss?

Types of Hair Loss Supplements

There are many different types of supplements that are marketed as hair loss treatments. Here are some of the most popular ones:


Biotin, also known as vitamin H, is a B-complex vitamin that is essential for healthy hair growth. It helps to produce keratin, a protein that makes up hair, skin, and nails.


Iron deficiency can lead to hair loss, especially in women. Iron supplements can help to increase the production of red blood cells, which carry oxygen to the hair follicles.


Zinc is an essential mineral that is important for hair growth and repair. It helps to keep the oil glands around the hair follicles working properly.

Saw Palmetto

Saw palmetto is an herbal supplement that is often used to treat hair loss in men. It works by blocking the production of DHT, a hormone that can cause hair follicles to shrink.

Vitamin D

Vitamin D is important for many bodily functions, including hair growth. Research has shown that people with hair loss often have low levels of vitamin D.

How Do Hair Loss Supplements Work?

Hair loss supplements work in a variety of ways, depending on the specific supplement. Here are some of the mechanisms by which they work:

Increasing blood flow to the scalp

Some supplements, such as ginkgo biloba, work by increasing blood flow to the scalp. This can help to deliver more nutrients and oxygen to the hair follicles, which can promote hair growth.

Providing essential nutrients

Many hair loss supplements contain vitamins, minerals, and other nutrients that are essential for healthy hair growth. By providing these nutrients, supplements can help to support the hair follicles and promote hair growth.

Blocking DHT production

Some supplements, such as saw palmetto and pumpkin seed oil, work by blocking the production of DHT. This hormone can cause hair follicles to shrink and eventually stop producing hair.

The Evidence for Hair Loss Supplements

While many supplements are marketed as hair loss treatments, not all of them have been proven to be effective. Here’s what the research says about some of the most popular supplements:


While biotin is essential for healthy hair growth, there is little evidence to suggest that taking biotin supplements can prevent or treat hair loss.


Iron deficiency can lead to hair loss, and iron supplements may help to reverse this. However, if you are not iron deficient, taking iron supplements is unlikely to improve your hair growth.


There is some evidence to suggest that zinc supplements may help to promote hair growth in people with zinc deficiency. However, more research is needed to determine whether zinc supplements are effective for hair loss in the general population.

Factors That Can Affect the Effectiveness of Hair Loss Supplements

While some hair loss supplements may be effective for certain individuals, there are several factors that can affect their effectiveness. Here are some things to consider:

  • Underlying health conditions: If your hair loss is caused by an underlying health condition, such as a thyroid disorder or autoimmune disease, taking supplements may not be enough to reverse it.
  • Nutritional deficiencies: If your hair loss is caused by a nutritional deficiency, such as iron or zinc deficiency, taking supplements may help to improve your hair growth.
  • Genetics: If your hair loss is caused by genetics, taking supplements is unlikely to reverse it. However, supplements may help to slow down the rate of hair loss.
  • Overall health and lifestyle: Your overall health and lifestyle can also affect the effectiveness of hair loss supplements. Eating a healthy diet, getting regular exercise, and managing stress can all help to promote healthy hair growth.

FAQs About Supplements for Hair Loss

Are Hair Loss Supplements Safe?

In general, hair loss supplements are considered safe when taken as directed. However, it’s important to talk to your doctor before taking any new supplements, especially if you are pregnant, nursing, or taking other medications.

How Long Does It Take to See Results from Hair Loss Supplements?

The time it takes to see results from hair loss supplements can vary depending on the supplement and the individual. Some people may see results within a few weeks, while others may take several months to see any improvement.

Can Hair Loss Supplements Cause Side Effects?

Hair loss supplements can cause side effects in some people, especially if taken in high doses. Common side effects may include upset stomach, diarrhea, and headaches. If you experience any side effects, stop taking the supplement and talk to your doctor.


In conclusion, while there are many supplements marketed as hair loss treatments, there is limited evidence to support their effectiveness. While some supplements may be helpful for certain individuals, it’s important to talk to your doctor before taking any new supplements. In addition, it’s important to address any underlying health conditions or nutritional deficiencies that may be contributing to your hair loss. By taking a comprehensive approach to hair loss, you can help to promote healthy hair growth and improve your overall health and well-being.
