Best rosemary hair serum: 6 top picks to stimulate hair growth
Avocados contain nutrients such as vitamin E, folate, niacin, magnesium, and vitamin C. Greek yogurt is much higher in protein than regular yogurt, with a six-ounce container providing 17 grams of protein, while the same serving of regular yogurt contains just six grams. Low protein intake can cause hair loss and thinning of the hair, so it’s important to consume protein-rich foods with every meal and snack.
Types of Foods to Support Hair Growth
This leafy green vegetable is known to have an insane amount of health benefits. Spinach is packed with high amounts of antioxidants such as lutein, beta-carotene, coumaric acid, and ferulic acid, according to a study published by Preventive Nutrition and Food Science. Not only this, spinach also has essential nutrients such as folate, iron, vitamin A, and vitamin C, all of which are necessary for hair growth.
Pumpkin Seeds
Red, green, yellow, or orange—whatever color you prefer, add bell peppers to your plate for a dose of extra hair-supporting nutrients. Avocados are delicious, nutritious, and a great source of healthy fats. However, biotin deficiencies are uncommon if you consume a balanced diet.
Fatty Fish
The brand claims that their product can promote 5 times faster hair growth. It may also help rejuvenate the scalp, nourish it from within and improve overall scalp health. This antioxidant helps prevent oxidative stress that may lead to hair loss,' says Gomer. Use avocados as a side with eggs or have some guacamole as a snack or meal component.

Oxidative stress from free radicals can play a role in the development of immune system diseases like alopecia areata. One study found that people with hair loss who took antioxidants in the vitamin E family had a significant increase in hair number (Beoy, 2010). Applying antioxidants to your scalp may help reduce hair loss and improve the condition of your scalp. The blood in your scalp goes to the follicle and supplies oxygen and nutrients to the hair root, which helps your hair grow. 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.

Trade Hair Growth Supplements for Healthy Fats
If you lack any of these nutrients, try adding some of the above foods to your diet. One medium oyster provides up to 96% of daily zinc needs for females and 75% for males (27). The most important step is to test your serum before using it for the first time. “Apply the serum to a small spot on the scalp for a few days to ensure that there is no irritation before applying it more broadly,” says Dr. Mirmirani.
Best Foods for Hair Growth, According to Nutritionists
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. An L-lysine deficiency can cause hair loss, but getting enough of this amino acid can prevent this issue and promote regular hair growth. Fish can be good sources of omega-3s as well as vitamin D, which can boost hair health. Brazil nuts are packed with selenium, which studies suggest can help with hair growth. One Brazil nut alone has up to 90 micrograms of selenium, so you’ll want to limit your intake to no more than four Brazil nuts per day. Selenium is also important for the production of thyroid hormones which help to regulate hair growth.
Bell Peppers
A provider can discuss your hair goals and prescribe medications to help, if indicated. Nuts and seeds supply the body with omega-3 fatty acids, vitamin E, and zinc, says Dr. Camp. Omega-3 fatty acids and vitamin E both possess anti-inflammatory properties that protect hair follicles from oxidative stress, he notes. “Zinc plays a role in protein synthesis in our body, including keratin—one of the main structural proteins that form hair,” explains Gans.
Apply antioxidants to your scalp
But, the research on spermidine and hair growth is fairly new, so more studies are needed before health experts can make recommendations on spermidine intake. Certain seeds like flaxseeds and chia seeds also provide omega-3 fatty acids. Nuts are tasty, convenient, and contain a variety of nutrients that are important for hair growth. Some studies have found lower levels of vitamin E in people with hair loss, but the evidence is conflicting (1). You should be able to get all the vitamin A you need by eating foods rich in this important nutrient.
Antioxidants are known to neutralise free radicals from the body cells and prevent or reduce the damage caused by oxidation. When it comes to your tresses, antioxidants combat oxidative stress, which can damage hair follicles and lead to hair loss and premature greying. Antioxidants such as vitamins A, C, and E, and minerals like selenium and zinc protect and nourish the scalp, stimulating hair follicles. This can enhance collagen production, enhancing hair strength, elasticity, and growth. According to a study published by the International Journal of Cosmetic Science, antioxidants can create a barrier on your hair, protecting it from sun damage.
Apart from eating, a study published in the International Journal of Trichology found that using avocado oil can help seal cuticle cells, preventing hair from breaking. "Avocados are rich in Vitamin E, an antioxidant that provides nourishment to the hair. Consuming just a medium-sized avocado provides approximately 28 percent of your daily vitamin E requirements," says Agyeman. This is most likely due to the antioxidant powers of vitamin E, which help reduce oxidative stress in the scalp. Gohara also notes that the healthy fats in avocados may contribute to overall hair health. Both Agyeman and Gohara clocked lean protein as a key nutrient for hair health. This makes sense, because the hair shaft is composed almost entirely of a protein called keratin.
Look for foods rich in "fat-soluble vitamins, B-complex vitamins, omega-3 fatty acids, and iron to support hair health," says Valerie Agyeman, RD, dietitian and host of women's health podcast Flourish Heights. Incorporating these nutrients into your diet can improve hair loss symptoms in certain cases, per a review of studies published in the journal Dermatology and Therapy. Deficiencies in protein, minerals, fatty acids, and vitamins can lead to hair loss, found a study published in Dermatology Practical & Conceptual and a review in Dermatologic Clinics. According to Pritchard, getting plenty of healthy fats like omega-3s can jump-start hair growth.
With that in mind, consider these the serums worth trying to achieve your unique hair goals. 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. The study was not double-blind (double-blind means that neither the participants nor the researchers know which treatment the individual participants are receiving).
Also, the toxins from smoking can seep into the hair follicles and cause disruption. Chicken not only packs protein, but also delivers an essential amino acid called L-lysine, which plays a role in iron and zinc uptake. As we learned, maintaining healthy zinc and iron levels can help avoid some of the most common barriers to hair growth.
