Vitamins and supplements are available to promote hair growth, and are sold over the counter. Vitamins can also be consumed through your diet. There are many reasons for hair loss or poor hair condition that may lead to breakage or slow growth. A poor diet will result in vitamin deficiencies. In turn, this will cause poor skin, hair and nail quality. Hair, in particular, will suffer because it will grow from the hair follicle without the support of vitamins. As a result, it will be weaker and thinner.
Biotin
Biotin is a vitamin that can combat hair loss, brittle nails and skin rashes. It is found in small quantities in many foods, such as tomatoes, carrots and romaine lettuce. There is some evidence that biotin supplements can reduce hair loss, according to MedlinePlus. Adequate intake of biotin in adults is 30mcg a day. Most multivitamins include this amount. Before taking any supplements, consult your health care provider.
Vtiamin B-1
Vitamin B-1 is also called thiamine. This is an essential vitamin for daily functions because it converts blood sugar into energy. Thiamine is needed for cellular activity, including the follicular cells of hair shafts. When these cells receive adequate energy, they regenerate more efficiently. Adults should have between 1.1 and 1.5 mg daily. B-1 is a water soluble vitamin, meaning it is excreted in the urine and is not stored in the body.
Vitamin A
Vitamin A is required to support the immune system and by the skin where hair follicles are formed. If an infection starts on the skin, whether it is a bacteria or virus, hair follicles will suffer. Vitamin A helps activate infection fighting cells such as white blood cells and T-lymphocytes. The recommended dose of vitamin A is 700 to 900 mcg daily for adults. Vitamin A can be found in multivitamins and food sources such as eggs, butter and whole milk.
