The 5 Most Important Vitamins for Hair Growth

Want longer locks? You're not alone. Whether you're growing out bangs or want floor length tresses, we know just how frustrating it can be to wait for an inch of hair to grow. To speed up the hair-growthВ process, we reached out to dermatologist Dendy Engelman, MD, for herВ recommendations on the best vitamins for hair growth.

According to Engelman, "genetics as well as life changes, pregnancy, menopause, and weight loss, contribute to the interference of hair growth" as do "chemical treatments, hot tools, brushes, and other styling tools." So, if you want long, strong locks, it's essential to give your hair and body the nutrients it needs, not just a weekly conditioning maskВ (although it couldn't hurt). For Engelman's hair growth tips as well as vitamin recommendations for longer healthier locks, keep reading.

DHT Inhibitors

Nutrafol Hair Supplements for Women $88Shop

The main culprit for female and male pattern baldness isВ DHT and androgens. To combat these hormones, Engelman recommends using the supplement Nutrafol, a combination of anti-inflammatories and antioxidants that work to reduce damage, natural vasodilators, which "revive follicles and increase scalp circulation," and a variety of vitamins, minerals, and amino acids to "regrow and support hair building blocks."В Essentially Nutrafol works toВ "rebalance hormone levels to reduce follicle damage," Engelman says.


Reserveage Keratin Booster with Biotin $40Shop

Engelman says nourishing the body with keratin is essential for promoting longer and stronger locks, as keratin is an essential "building block of healthy hair," helping hair to grow "thick and strong throughout the growth cycle." She recommends usingВ Reserveage's Keratin Powder, which "containsВ CynatineВ HNS Keratin powder that is processed into easily absorbed protein peptides" as well as "biotin and vitamin B3, B5, B6, copper, and zinc" all of which areВ beneficial to overall hair health.

Iron plays an important part in hair health, as "low levels of iron can lead to hair loss, and the fix may be as simple as adding an iron or vitamin supplementВ or adding lentils, eggs, and spinach to your diet," Engelman says. If you think iron might be the culprit for your lack of hair growth, have a doctor check your levels, and look for a proven hair supplement that includes iron as one of the main ingredients.

Vitamin A

Pure Vitamin A $8Shop

An important vitamin when it comes to hair and scalp health is vitamin A, as it "is used by cells to produce sebum, which helps keep the scalp moisturized," which in turn "supports healthy hair growth," Engelman says. If you think vitamin A could be the culprit for your lack of hair growth, Engelman recommends adding dairy to your diet, or if you want to take a supplement, consult your doctor for the correct dosage of vitamin A for your body.


Vibrance Hair Growth Vitamins Biotin and MSM $29Shop

Biotin deficienciesВ are associated with hair loss. If you think thatВ might be your hair health issue, talk to your doctor about taking biotin, which Engelman says is "an essential vitamin for body tissue including hair, skin, and nails." By taking biotin, you are supporting "the growth of hair, skin, and nails by helping to break down fats and carbohydrates." If you don't want to take a capsule, Engelman recommends incorporating hearty foods like beef, chicken and potatoes to your diet.
