It is sometimes called vitamin H or B7 and has large influence on the condition of hair. Biotin influences hair to a considerable extent and is a very important ingredient, the deficiency of which may lead to hair loss. How to protect from this? In which products will you find biotin?
Biotin is essential for the proper growth of hair
It is a component of enzymes, the task of which is to catalyze the reaction of carboxylation – which in the “human” language means the processes taking place in the synthesis of sugars, proteins and lipids. According to researchers, problems with hair and skin in people with biotin deficiency are related to the disorders of fat metabolism.
Biotin is also a natural source of sulfur, which in turn is essential to produce creatine, i.e. a basic building block of hair and nails.
Biotin also inhibits hyperactivity of sebaceous glands. Excessive secretion of sebum may lead to seborrheic dermatitis – a common cause of baldness. Additionally, it is worth mentioning that biotin is important for the proper work of the thyroid gland, the disorders of which are also the cause of deterioration of hair condition and its loss.
What are the causes of biotin deficiency?
The cause may be intrinsic deficiency of biotinidase. However, most often deficiencies are related to bad diet and pharmacological treatment. Biotin is displaced by the ingredients of anti-convulsant drugs, such as phenytoin or carbamazepine. There also occur the disorders in the absorption of this vitamin. Biotin deficiencies are also observed among people, who have gone through a long-lasting antibiotic-therapy. Therefore, a side effect of the treatment are often nail brittleness, inhibition of hair growth and its worse condition.
A point of interest
Biotin is “forced out” from the organism by alcohol. Therefore, it should be quit in the period of fighting with hair loss.
Which products are the source of biotin?
Vitamin B7 is present in many food products. They are i.a. liver, egg yolk, soya, lentil and yeasts. However, in case of biotin deficiency, its natural sources are not sufficient and supplementation is needed.
A piece of advice
The most valuable supplements also contain – apart from vitamin H – zinc, silicon and gelatin hydrolysate, i.e. the key components for proper hair growth. However, pregnant women should be careful with such supplements, as it was proven that biotin may permeate to mother’s milk. Therefore, it is better not to take this vitamin in the form of tablets during pregnancy and breastfeeding.
There is also a strong relationship between biotin deficiency and problems with hair loss. However, before you reach for supplements, consult with trichologist – the cause of your problem may be somewhere else.
