BIOTIN

Keratin is a basic protein that makes up your hair, skin, and nails. Biotin improves your body’s keratin infrastructure therefore it stimulates keratin production in hair and increases the rate of follicle growth. The primary benefit of biotin for hair is that it allows stronger and healthier hair growth. Stronger hair is less likely to break off at the ends, promoting and protecting its length.

IRON

Our hair follicles receive nourishing oxygen from the iron in our red blood cells. A more common problem people encounter is that they may have low ferritin—the “bank” of iron our body keeps to draw on when it needs it. Low ferritin has been linked to slow or halt in hair growth, as well as shedding. Taking iron in supplements helps boost circulation and carries oxygen to the hair's roots, which helps it grow faster and longer.

CALCIUM

Calcium is one of the most important ingredients for maintaining a healthy scalp. Calcium relieves itching due to inflammation. Also, it forms a skin barrier to protect it. Keeping your scalp healthy, helps to stop hair loss effectively. Additionally, Calcium is an essential mineral that gives your hair a natural shine. Calcium helps in generating new cells so your skin’s elasticity is maintained while the dead, dull skin is easily shed. Skin that lacks calcium in the epidermal layer looks thin, dry, and dull. If you are experiencing hair thinning or hair loss, you should have foods that are rich in calcium or take supplements with them.

Zinc

Zinc plays an important role in hair tissue growth and repair. It also helps keep the oil glands around the follicles working properly. Hair loss is a common symptom of zinc deficiency. It usually leads to changes in the protein structure of hair follicles leading to the weakening of their structural integrity. This means new hairs will fall off quicker than they should. Zinc also helps to keep hormone levels regulated, which is one of the reasons why it is so effective in preventing and treating hair loss.

Vitamin B6

One of Vitamin B6’s greatest benefits is its ability to balance the production of sebum, the oil naturally produced by our skin and scalp. When its production is in overdrive, the result is greasy skin and scalp, which can also mean clogged pores.

Research has examined the effect of Vitamin B6 on volunteers with acne breakouts. The vitamin decreased the amount and severity of acne in participants by decreasing the amount of oil produced by the skin.

There was also a study conducted by the British Journal of Dermatology in 2007, in which they found that the combination of Vitamin B6 with zinc can inhibit 90% of the harmful activity of testosterone, which forms DHT in the hair follicle and causes hair loss. Vitamin B6 also helps in natural hair color restoration by increasing the formation of melanin, hair’s natural color pigment, in the body.

IODINE

Iodine is a micronutrient that plays a significant role in not only the growth of your hair but also the growth and development of all the organs and tissues in your body. This essential mineral helps in making and regulating thyroid hormones. If your body does not get enough iodine, your thyroid gland cannot produce thyroid hormones, which results in the shrinking of hair follicles. Lack of iodine leads to dry and brittle hair, hair thinning, and hair loss.

Vitamin E

Vitamin E has been used in dermatology since the 1950s to help protect the skin against aging, inflammation, and sun damage. Vitamin E is essential for healthy skin — and this includes your scalp. Poor scalp health is linked to lackluster hair quality. Vitamin E supports the scalp and gives your hair a strong base to grow from by reducing oxidative stress and preserving the protective lipid layer.
