Supplements have become a popular addition to many beauty and wellness routines—and for good reason. While hair thinning can be caused by a variety of factors like stress, hormonal changes, or nutritional deficiencies, certain supplements may help support healthier, fuller hair from the inside out.
To find out about these game-changing supplements, we checked in with Dr. Elaine F. Kung, MD, FAAD, board-certified dermatologist and founder of Future Bright Dermatology, Dr. Enrizza P. Factor, dermatologist and writer at My Eczema Team, and Ghanima Abdullah, hair expert and cosmetologist at The Right Hairstyles. Read on to get all their tips and suggestions.
Women Are Swapping Their Boring Water For This Ice Pop Electrolyte Mix!
1. Vitamin D
While you might associate vitamin D with sunshine and bone health, this nutrient also plays an important role when it comes to your hair and scalp health. Kung says that "studies show that female pattern baldness can be improved by supplementing the diet with low levels of vitamin D."
She adds that "one of the most dermatologist-recommended supplements for hair growth is Nutrafol," launched in 2016. Factor notes that "consuming a diet lacking the right nutrients, including vitamin D, can lead to hair loss."
On the other hand, she says that "eating a balanced diet with vitamin D can help promote hair growth, especially if you’re experiencing hair loss due to poor nutrition."
2. Biotin
This water-soluble B vitamin is often found in our favorite foods and hair products, and it can also be taken as a supplement. Factor notes that biotin is "also known as Vitamin B7 or Vitamin H, and a part of the B-complex vitamins." When it comes to hair growth, biotin is one of the most talked about topics in the beauty world. Abdullah says that this is for good reason. She notes that biotin is a no-fail supplement choice if your goal is to grow back longer, healthier and fuller tresses.
"Biotin is worth it. It increases circulation to the scalp to aid hair growth and stop hair thinning," she says. Factor agrees, and notes that a lack of biotin in your diet "may slow down hair growth or even cause hair loss." Fortunately, she says, "correcting a deficiency in this nutrient may help treat hair loss and promote the rate of hair growth."
Abdullah adds that biotin supplements can "stimulate hair growth by increasing energy synthesis within the blood and delivering more blood flow to the scalp." She dubs biotin to be a "building block for keratin, which is also used by the hair, skin and nails."
Having sufficient biotin in the body, she says, contributes to "longer, stronger, shinier hair and nails and better skin elasticity," as well. Biotin, she continues, helps "increase circulation to the scalp, which helps the hair follicles produce a better quality of hair and more of it."
3. Pumpkin Seed Oil
Abdullah explains that a pumpkin seed oil supplement has "been scientifically proven to grow more hair and aid those who have thinning hair."
She goes on to say that "pumpkin seed oil is worth it as a supplement ingredient, or even all by itself." She shares that vitamin D, biotin and pumpkin seed oil may be more beneficial to try than "collagen, elastin, and coconut oil" supplements.
The Bottom Line
Abdullah, Factor and Kung stress that it is always essential to visit a dermatologist or another hair specialist to decide which supplement or solution is best for your personal hair thinning situation! One supplement will not treat everyone's individual hair loss or thinning hair problem, they say, and taking many at once will not either. When prioritizing your hair health, Factor says to look at your diet, first and foremost.
"How fast your hair grows depends on factors like age, health, genetics and diet. Although you can’t change factors like age and genetics, diet is one thing you have control over," she explains. "In fact, consuming a diet lacking the right nutrients can lead to hair loss. On the other hand, eating a balanced diet with the right nutrients can help promote hair growth, especially if you’re experiencing hair loss due to poor nutrition," she continues.
