Eggs are a great source of protein and biotin, two nutrients that may promote hair growth.
Eating adequate protein is important for hair growth because hair follicles are made of mostly protein. A lack of protein in the diet has been shown to promote hair loss.
Biotin is essential for the production of a hair protein called keratin, which is why biotin supplements are often marketed for hair growth. Research has also shown that consuming more biotin can help improve hair growth in people with a biotin deficiency.
However, biotin deficiencies are uncommon if you consume a balanced diet. There is little evidence to show healthy people benefit from consuming more biotin.
Eggs are also a great source of zinc, selenium and other hair-healthy nutrients. This makes them one of the best foods to consume for optimal hair health.
Spinach is a healthy green vegetable that’s loaded with beneficial nutrients like folate, iron, and vitamins A and C, all of which may promote hair growth.
Vitamin A helps the skin glands produce sebum. This oily substance helps moisturize the scalp to keep hair healthy.
A cup (30 grams) of spinach provides up to 54% of your daily vitamin A needs.
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.
3. Fatty Fish
Fatty fish like salmon, herring and mackerel have nutrients that may promote hair growth.
They are excellent sources of omega-3 fatty acids, which have been linked to hair growth.
A study in 120 women found that taking a supplement containing omega-3 and omega-6 fatty acids as well as antioxidants reduced hair loss and increased hair density.
Another study found that taking a fish oil supplement significantly reduced hair loss and increased hair growth in women with thinning hair.
Fatty fish is also a great source of protein, selenium, vitamin D3 and B vitamins, nutrients that may help promote strong and healthy hair.
4. Sweet Potatoes
Sweet potatoes are a great source of beta-carotene. The body converts this compound into vitamin A, which is linked to good hair health.
A medium sweet potato (about 114 grams) contains enough beta-carotene to provide more than four times your daily vitamin A needs.
Research has shown that vitamin A promotes the production of sebum, which helps keep hair healthy.
Vitamin A could also speed up the rate of hair growth and encourage the growth of thicker hair, all while preventing other hair follicles from regressing.
The benefits of tangerines affect your hair in a big way. Their vitamin C content makes it easier for your body to absorb iron, which is found in foods like red meat and spinach. Iron deficiency has been linked to hair loss, according to a study published in the Journal of Korean Medical Science, so it’s important to make sure you’re getting enough of it. And vitamin C foods will only help your body absorb that iron even more.
6. Greek Yogurt
Greek yogurt contains vitamin B5 (known as pantothenic acid), and B vitamins can help you maintain healthy skin and hair.
