The study was not double-blind (double-blind means that neither the participants nor the researchers know which treatment the individual participants are receiving). The study's authors were employees of the company that commercialized the product. A 2022 study on in vitro (out of the body, typically using test tubes and similar equipment) human dermal papilla cells and mice found some potential positive effects from fish-derived collagen peptides. These findings suggest that fish-derived collagen peptides could, at some point, be used to promote hair growth, but more research is needed on humans to confirm this finding. When you don't have enough, you can experience hair loss — even in your eyelashes! Dr. Debé notes that zinc supplementation has been shown to improve hair loss in women with polycystic ovary syndrome (PCOS), according to a Biological Trace Element Research study.

Fatty fish is also a great source of protein, selenium, vitamin D3, and B vitamins, which may help promote strong and healthy hair (11). While more research is needed to understand the connection between micronutrients and hair loss, ensuring you’re getting enough of these 13 foods rich in nutrients that support hair growth is a good idea. While many products do provide applicator nozzles that reach through the hair, some droppers aren’t as precise. There is a commercially available food supplement tablet containing hydrolyzed fish-origin collagen (300 mg/dose), taurine, cysteine, methionine, iron, and selenium, marketed for people with hair loss disorders. There is no controlled data showing the efficacy of this product as an addition to specific treatments for hair loss conditions. A 2023 study found that participants given this supplement had a better response to hair treatments than those who received the treatments alone, but the study had several limitations.
Warning signs of hair loss
That’s why getting zinc from foods like oysters may be better than supplements since foods provide zinc in small but healthy doses (29). Oxidative stress occurs when free radicals overwhelm the body’s antioxidant defense system. Certain seeds like flaxseeds and chia seeds also provide omega-3 fatty acids. Some studies have found lower levels of vitamin E in people with hair loss, but the evidence is conflicting (1).

Best vitamins for hair growth: Vitamin D, B complex, biotin, and more.

Leafy greens, like spinach, contain folate and iron, which are both important for maintaining a healthy blood supply to your hair. They also contain vitamin C, which assists with strengthening collagen production, says Taub-Dix. B vitamins as a whole (there are several of them) and folate have been linked to hair loss prevention, biotin often receives the biggest spotlight when it comes to hair. With vitamin C’s important role in collagen production, and vitamin A’s role in sebum production, both vitamins do wonders for your scalp health.
Nuts and seeds
Eggs are a good source of hair-healthy nutrients like biotin and protein. When it comes to healthy hair, lately there's a lot of buzz about biotin -- a nutrient found in egg yolks. This could be because zinc helps with protein synthesis, cell growth and hair follicle development, per a January 2017 paper in Dermatology Practical & Conceptual. Pumpkin seeds contain zinc, which is thought to prevent hair loss, according to the International Food Information Council Foundation. When you don't have enough of this mineral in your diet, you can have hair loss -- even in your eyelashes.
Use it as a swap for oatmeal at breakfast or rice in a stir-fry, and try buckwheat-based Udon when making ramen or other noodle dishes. The ultimate in deliciously healthy breakfasts—we love it smashed on whole grain toast sprinkled with sea salt—the creamy avocado is packed with healthy fats and biotin. It's also a popular ingredient in many DIY hair masks (hello, self-care Sunday). Avocados also contain vitamin E, an antioxidant that nourishes the hair.
You can have your salmon grilled, broiled, raw, or mixed in with scrambled eggs—a great source of biotin. Don’t overlook the importance of getting enough protein if you’re looking to bring on some hair growth. Dermatologists treating hair loss look at the level of ferritin in your blood, because they can deduce what your body is doing with all the iron they told you to add to your diet during your initial consultation. If you'd been eating plenty of bok choy—which is a super iron-rich food—they would likely see a spike in your ferritin levels. In some cases (particularly in women), a mineral deficiency is the cause of hair loss. "It's important to make sure you don't have a lack of something in your diet that could be leading to hair loss," says dermatologist Carolyn Jacob, MD, FAAD.
Collagen Types and Hair Application
Both Gomer and Yawitz say vitamin E is an antioxidant that helps prevent oxidative stress that may lead to hair loss, since it can help protect the hair follicles from damage. Vitamin E is a powerful antioxidant that can actually absorb damaging UV light and protect skin cells. It also repairs sun damage on the scalp, which can cause hair to thin.

Fueling up with enough calories and healthy fats does more than keep your muscles and heart healthy. Research in a January 2015 study from the Journal of Cosmetic Dermatology showed that omega-3 and omega-6 essential fatty acids could help reduce hair loss and improve hair growth. Salmon is also an excellent source of omega-3 fatty acids, a key nutrient for healthy hair. In one study, a majority of women who took omega-3 and other supplements reported a reduction in hair loss as well as an improvement in hair diameter and hair density. Your body doesn't naturally produce omega-3s, so you will have to get them from food or supplements. Unprocessed, natural food sources are the best places to look for essential vitamins and nutrients in hair growth.

The health of your hair is complex and may depend on dietary, lifestyle and environmental factors. When it comes to meeting your nutritional needs in the most hair-healthy way, experts recommend food over supplements. Nutrients in foods are more easily absorbed by the body than those in supplements.
