Rather, eating a balanced, nutritious diet that provides the necessary macro and micronutrients can help hair growth. This includes protein sources like fatty fish and red meat and plant foods high in vitamins and other nutrients like spinach, seeds, and nuts. When applied to the scalp, minoxidil is believed to widen blood vessels, promoting increased blood flow to hair follicles. This improved circulation is thought to stimulate hair growth and is often used to address conditions such as androgenetic alopecia, commonly known as pattern baldness.

Spinach is also a great plant-based source of iron, which is essential for hair growth. Iron helps red blood cells carry oxygen throughout the body to fuel your metabolism and aid growth and repair (8). Spinach is a healthy green vegetable loaded with beneficial nutrients like folate, iron, and vitamins A and C, which are important for hair growth (7). Low iron levels may cause iron deficiency anemia, which has been linked to hair loss (1). Biotin is essential for the production of a hair protein called keratin, which is why biotin supplements are often marketed for hair growth. Biotin can help improve hair growth in people with a biotin deficiency (3).
Growing Your Hair Out: Short to Long
More recent research from 2019 found that 68.9% of 340 participants reported “hair loss stabilization or regrowth” after performing scalp massages twice per day. However, diet and nutrition can affect how healthy the hair is, and some deficiencies can cause hair growth to slow down. The protein in meat aids growth and helps repair and strengthen hair follicles. A 3.5-ounce (100-gram) serving of cooked sirloin steak provides as much as 29 grams of protein (34). Like oysters, beans are a good source of zinc, which aids the hair growth and repair cycle.

Applying an oil-based product directly to the scalp has been shown to improve the scalp's condition. This, in turn, can promote healthy hair growth and cut back on hair loss caused by stress. A 2020 review suggests that caffeine in topical products, like shampoos and conditioners, could prevent hair loss as effectively as drug-based treatments. Caffeine may promote hair growth by stimulating the metabolism and proliferation of cells. Because of antibacterial and antifungal properties, many essential oils like tea tree oil are effective for targeting conditions like dandruff or scalp eczema. This keeps the hair and scalp healthy and moisturized, supporting an optimal environment for hair to grow.
In one older study, people with hair loss experienced 34.5% more hair growth after taking a vitamin E supplement for 8 months (17). However, there are only a handful of studies on omega-3 fatty acids and hair growth. More studies are needed before health experts can make any recommendations. Eggs are a great source of protein and biotin, two essential nutrients for hair growth. Sometimes, a healthcare provider may recommend a prescription medication treatment to help with hair growth. That said, many different types of hair oil products are on the market, and there's not a one-size-fits-all ingredient that's been scientifically proven to produce hair growth results.
For example, an ounce (28 grams) of almonds provides 48% of your daily vitamin E needs (19). A cup (30 grams) of spinach provides up to 20% of your daily vitamin A needs (7). For example, 1 cup (144 grams) of strawberries provides 85 milligrams or up to 113% of your daily vitamin C needs (6). Although you can’t change some of these factors, you likely have more control over your diet. Almost as important as what you use to brush your hair is when you choose to do so. Instead of detangling after the shower (when your hair is at its most vulnerable and fragile), comb through your knots before you wash your hair.

Have a scalp massage
Additionally, according to a 2019 review of research, using a heat-protectant product before using a heated styling tool may significantly reduce hair breakage. The researchers from the above study suggest that treatments can be once a month, for 3 months, and every 6 months thereafter for maintenance. Keep reading to learn 14 ways you can help your hair grow and prevent breakage. This phase is transitional and marks the change between the growth phase and the resting phase.
Avocados are a great source, and they're also rich in vitamins E and B(s). A nutritious diet with the recommended essential nutrients, including protein, antioxidants, iron, and fatty acids, can help support healthy hair growth. Avoiding deficiencies can help prevent hair loss due to a lack of nutrients.
Naturally Stimulating Hair Growth (Without Supplements)
Generally, it’s best to get your vitamins and nutrients from your diet. Still, you may also look into taking certain supplements — particularly if you have a deficiency. Still, there are steps you can take that may promote healthy hair during the anagen phase. Eating a healthy, nutrient-dense diet that includes adequate protein is key. Using certain products and treatments may also help, while dialing back on heat treatments and chemical processing can help, too. The heat from curling irons, hair dryers, and straighteners could damage your hair and cause breakage.
Some studies have found that light therapy was able to significantly increase hair density after several weeks of use. Certain types of light therapy may encourage hair growth and cut down on hair thinning. Research suggests that using a scalp massage device can help promote hair strength, thickness, and growth.
Some of the best foods for hair growth are foods with high nutritional value, like eggs, leafy greens, and fatty fish. Like other scalp oils, castor oil typically is massaged into the scalp and left on overnight to help boost hair growth. Note that there isn't direct scientific evidence supporting the use of castor oil for hair growth, so check with a healthcare provider before adding this to your hair care routine. Some studies have shown certain essential oils like rosemary oil to be as effective as medicated topical products for regrowing hair in certain cases. You may want to try other nutrient-rich oils—like coconut oil, argan oil, and olive oil—that have moisturizing fatty acids that can support a well-nourished scalp.
This stress triggers the activation of dormant hair follicles and encourages the expression of genes responsible for promoting hair growth. Scalp massages also reduce the activity of genes linked to hair loss. It might sound counterproductive when you want your hair to grow longer, but regular trims get rid of dry, damaged split ends and are necessary for natural, healthy growth.
While several hair growth factors are out of our control, eating a nutrient-rich diet, stress management, and gentle hair care practices may help you grow your hair. Hair growth is a complex process that hinges on several different factors. Key nutrients, like omega-3 fatty acids, biotin, and other vitamins, are important for growing hair. Foods such as eggs, fatty fish, dark, leafy greens, meat, bell peppers, and more contain the nutrients to help keep hair healthy.
The set includes almond, avocado, castor, coconut, and grapeseed oils. If you’re new to carrier oils, this is a good way to try multiple types without investing in larger bottles of each. How long the anagen phase lasts depends on how long your hair is and if the cells in your follicle base are continuing to multiply and become hair cells. It’s important to note that little research supports these natural treatments. Heat treatments work by forming a protective barrier that helps prevent moisture loss when using heated tools.
Bond-building treatments, such as Olaplex or similar products, are designed to repair and strengthen damaged hair. While they don't directly stimulate hair follicles or increase the rate of hair growth, they may indirectly support healthier hair growth by improving the overall condition of the hair. It works by stimulating hair follicles to enter the anagen (growth) phase of the hair growth cycle and increasing blood flow to the scalp. Keeping your scalp clean promotes healthier hair growth by creating an optimal environment for hair follicles. Additionally, a clean scalp helps reduce the risk of scalp infections, inflammation, and dandruff, which can negatively impact hair health and growth. According to Pritchard, getting plenty of healthy fats like omega-3s can jump-start hair growth.
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. Other studies suggest spermidine may promote human hair growth (33). Certain seeds like flaxseeds and chia seeds also provide omega-3 fatty acids.
