What is hair loss?

Vitamin deficiencies that cause hair loss

Vitamins and minerals play a key role in the normal development of hair follicle, which is needed for hair growth. Deficiency of such nutrients may lead to hair loss, according to research published in Dermatology And Therapy journal in 2018.

Vitamin deficiencies that cause hair loss:

1. Thiamine or vitamin B1

It is important for the metabolism of cells, including those in hair follicles, as it helps in carbohydrate metabolism to generate energy. Hair follicles require a steady supply of energy to promote hair growth“A deficiency in thiamine may result in insufficient energy for the hair follicles, potentially leading to weakened follicles that struggle to produce new hair,” says the expert. Adults can have 25 mg of vitamin B1 once a day, according to the UK’s National Health Service,

2. Vitamin B2 (Riboflavin)

When it comes to vitamin deficiencies that cause hair loss, don’t forget riboflavin. It is necessary in building energy and healthy tissues, among other things, including hair follicles. “Furthermore, riboflavin supports iron metabolism, the process that allows enough oxygen to be available to the scalp and to the hair roots to have healthy hair,” says the expert. In adults, the average daily riboflavin intake is 4.7 mg in women, according to the US National Institutes Of Health,

3. Vitamin B5

Pantothenic acid or vitamin B5 is involved in synthesizing coenzyme A needed in fatty acid metabolism, along with energy synthesis. “This helps in improving hair strands’ flexibility, strength, and the nutritional feeding of hair follicles,” says the expert. Hair loss and brittleness may be caused by a deficiency in pantothenic acid. Have 5 mg of pantothenic acid in a day, as per the US National Institutes Of Health,

4. Vitamin B6

Pyridoxine, commonly referred to as vitamin B6, is essential for neurotransmitters that can regulate hair growth and the breaking down of proteins. “It further assists in the regulation of hormones, particularly those related to hair. Vitamin B6 deficiency might cause weak hair and further hair loss,” says Dr Bhatt. Since it is one of the many vitamin deficiencies that cause hair loss, consume 1.7 mg of vitamin B6 in a day, as per the US National Institutes Of Health,

5. Vitamin B7

The synthesis of keratin is a protein that gives hair its shape and growth, and it relies on vitamin B7 or biotin. It functions as a coenzyme for metabolism in glucose, fatty acids, and amino acids in the body, processes involved in energy production and maintaining healthy hair follicles. “Biotin deficiency may lead to disrupted keratin production that can cause hair loss or brittle, thinning hair,” says the expert. Thirty mcg of biotin is recommended for adults, as per the US National Institutes Of Health,

6. Vitamin B9

Discussion on vitamin deficiencies that cause hair loss is incomplete without vitamin B9. More commonly known as folic acid, it is essential to cell growth and repair, aiding in healthy hair follicle growth. It is further important in the formation of red blood cells, crucial for the growth of hair. “Folic acid deficiency can lead to weak hair, slow growth, and thinning,” says the expert. The daily recommended intake of this vitamin for adults is 400 mcg, as per the US National Institutes Of Health,

7. Vitamin B12

Cobalamin, which is vitamin B12, helps to facilitate hair growth by creating red blood cells that eventually carry oxygen into the scalp and hair follicle. Sustaining good hair follicle function and encouraging hair growth require an adequate supply of oxygen and nutrients. “Vitamin B12 deficiency causes poor oxygen transport that can weaken the hair follicles and eventually lead to hair loss. You must have 2.4 mcg of vitamin B12 in a day, according to the US National Institutes Of Health,

8. Vitamin D

Vitamin D helps to nourish hair follicles, the small pores from which new hair grows. So, have it to avoid vitamin deficiencies that cause hair loss. This vitamin plays a role in the creation of new hair follicles, and so, may help to maintain hair volume. To avoid Vitamin D deficiencyhave 10 mcg of this nutrient a day, according to UK’s National Health Service,

9. Vitamin E

Among the vitamin deficiencies that cause hair loss, vitamin E has a spot. It has antioxidant properties that may help reduce oxidative stress, which can cause hair loss by damaging the scalp as well as hair follicles. Without this vitamin, you may experience hair loss. It may also help to promote hair growth. A 2010 study published in the Tropical Life Sciences Research The journal showed vitamin E improved hair growth in participants with hair loss. The daily intake is 15 mg for adults, according to the US National Institutes Of Health,

• There are shampoos with vitamins like D and biotin that can be used to promote hair growth. Topical applications, such as minoxidil, especially the one with vitamin D, can also be used to stimulate blood circulation and strengthen hair follicles. These products target the scalp directly, complementing internal supplementation.
