Top Supplements for Hair Health

If you’re noticing more strands in your hairbrush, you’re not alone. Hair thinning and slow growth are common concerns for both men and women, and they can stem from a wide range of causes—everything from stress, hormonal changes, nutrient deficiencies, aging and more.¹ Even over-styling can impact the health and strength of your hair. Targeted supplements for hair can make a difference. By nourishing your body from within, the right blend of vitamins, minerals and botanical ingredients can help support hair follicle function, improve scalp circulation, strengthen strands and encourage thicker, faster-growing hair over time.^2,3

Vitamin D

Vitamin D plays an important role in the hair growth cycle by supporting the development and vitality of hair follicles.⁴ Supplementing vitamin D can help restore healthy follicle function, potentially stimulating dormant follicles and promoting new growth. It may especially benefit individuals with limited sun exposure.

Vitamin C

Vitamin C is essential for healthy hair because it supports collagen production. Collagen is a key structural protein that helps strengthen and protect your hair. Vitamin C is also a powerful antioxidant, protecting hair follicles from damage caused by free radicals (unstable molecules that can weaken hair growth).⁵ Additionally, vitamin C enhances the body’s ability to absorb iron, a mineral vital for strong, healthy strands. Supplementing with vitamin C can contribute to more resilient hair and support overall scalp health.

Folic Acid

Folate, (or its synthetic form, folic acid), is also known as vitamin B9 and plays a crucial role in cell division and tissue growth. These processes are essential for healthy hair production. When the body doesn’t get enough folate, it can disrupt the normal functioning of hair follicles, leading to thinning or slowed growth. Supplementing with folate may help support the renewal of hair cells, improve scalp circulation and encourage stronger, fuller hair. It’s especially vital during periods of rapid growth or hormonal change when folate levels can directly impact hair health.

Zinc

Zinc is a vital mineral that plays a key role in hair tissue growth and repair, as well as maintaining the oil glands around hair follicles. Zinc supplements may help restore healthy follicle function, reduce hair thinning and promote regrowth, especially in individuals with low zinc levels. Additionally, zinc has antioxidant properties that support scalp health and protect follicles from damage. However, it’s important to follow the recommended dosages as too much zinc can interfere with the absorption of other essential nutrients and impact hair quality.

Collagen

Collagen supplements may help protect your hair by supporting the structure and health of hair follicles. Collagen is a protein rich in amino acids like proline and glycine, which are building blocks for keratin—the primary protein that makes up hair. As we age, the body’s natural collagen production declines. This can contribute to weaker hair and thinning strands. Taking collagen supplements may help strengthen the scalp’s connective tissue, reduce breakage and promote thicker, healthier-looking hair over time.^8,9

What is the Best Supplement for Hair Loss?

While there’s no magic pill for instantly restoring a full head of hair, the right supplements can play a powerful role in supporting healthy growth from the inside out. Nutrients like vitamin D, vitamin C, folic acid, collagen and zinc each contribute to the strength, structure and vitality of your hair in different but complementary ways. Whether you’re dealing with shedding, thinning or just want to give your strands a boost, targeted supplementation can help fill nutritional gaps and create an optimal environment for hair to thrive. As always, consult with a healthcare provider before starting any new supplement routine. With consistency, patience and the right nutrients, healthier hair could be just a few steps away.

You be well, now.
