The best hair growth vitamins and supplements of 2024, according to experts

The best hair growth vitamins and supplements of 2024, according to experts

Hair loss or thinning is a natural part of life. While it can be a side effect of something like COVID-19, it can also happen because of other underlying causes like iron deficiency or nutrient deficiency. In fact, 35 million men and 21 million women suffer from hair loss in the United States, according to the Hair Society. Shedding and hair loss can happen for a multitude of reasons. Dr. Michelle Henry, board-certified dermatologist, tells AOL, “Among the multitude of factors contributing to hair loss, hereditary hair loss, also known as androgenetic alopecia, stands as the most prevalent cause. While genetics play a significant role, other factors such as stress, illnesses, hormonal imbalances, nutritional deficiencies, and certain medications can also contribute to hair loss.”

What key ingredients should I look for in the best hair growth vitamins?

A variety of factors can cause hair loss, so what you find to be effective may differ from what works for someone else. However, there are some key ingredients our experts recommend that you should look for when selecting the best hair growth vitamins.

"Look for specific ingredients that have shown efficacy in promoting hair growth. Biotin, also known as vitamin B7, is one of the most widely recognized nutrients for hair health. Studies have shown that biotin supplementation can improve hair thickness and increase hair growth rate," Dr. Michele Green, a board-certified dermatologist specializing in hair loss and research advisor at Gya Labs, tells AOL.

"Other essential vitamins and minerals that support healthy hair growth include vitamin D, vitamin E, vitamin C, iron, zinc, and omega-3 fatty acids. These nutrients contribute to the production of necessary proteins and antioxidants that promote hair growth and protect hair follicles," Green adds.

How we chose the best hair growth vitamins and supplements

When selecting the best hair growth vitamins and supplements, we spoke to dermatologists and scoured the internet for the highest-rated products on the market. We considered factors like active ingredients, user reviews and ratings, price, and product availability. Ultimately, we narrowed it down the nine best hair growth vitamins and supplements, which contain a combination of effective ingredients in a range of price points to fit each budget.

Hair growth vitamins and supplements FAQs

How do hair growth vitamins and supplements work?

Hair growth vitamins and supplements work by nourishing the body with the necessary vitamins and minerals for improved hair growth, such as biotin, vitamin D, vitamin E, vitamin C, iron, zinc, and omega-3 fatty acids. These nutrients help promote existing hair growth and improve hair strength for a thicker, healthier head of hair.

How long does it take to see results from hair growth vitamins and supplements?

The effects of hair growth vitamins and supplements vary from person to person, as each individual's hair growth cycle is unique. According to Dr. LoGerfo, consumers should allow at least 4 to 6 months of consistent use before expecting to see changes in hair growth.

"Patience is key when utilizing hair growth supplements, as the benefits often become evident after extended periods of use," Dr. Green adds.

Are hair growth vitamins and supplements safe for everyone to take?

"Hair growth vitamins and supplements are generally considered safe for most individuals when taken as directed," Dr. Green tells AOL. "It's essential, however, for people to consult their doctor before starting any new dietary supplements, especially if they have pre-existing medical conditions or are taking medications that could potentially interact with the supplements," she adds. Additionally, pregnant or breastfeeding women should always consult with their healthcare provider prior to starting any new dietary regimen.

What other types of hair growth products are available?

When it comes to hair growth products, it all comes down to clinically proven key ingredients and product preferences. You may not have much time in your daily routine, so a supplement, vitamin or a shampoo for thinning hair may be best for you since it does not require you to add any extra steps to your normal hair care regime. Perhaps you have a very dry scalp and split ends, in that case, a hair growth oil or serum may be a better bet. We have also created an article on the various product types and needs surrounding hair loss and thinning, to further help our readers find their best hair growth product.

When should I see my doctor about hair loss?

Although some shedding (around 50 to 100 hairs per day) is considered normal, more rapid hair loss or an absence of new growth can be a sign that something is off. If you're experiencing significant hair loss, it's important to see your doctor for medical advice and treatment options. Dr. Andy Goren, board-certified dermatologist says early intervention is key: "Most patients only notice hair loss when approximately 50% of the hair has been lost in a region on the scalp; thus, early diagnosis with tests such as a genetic test for androgenetic alopecia could provide the best chance for successfully treating hair loss before it is visible."
