Biotin supplements have flooded the market. From Biotin shampoo to powders, Biotin has taken the market by storm. Ever wondered what the hype is about? Well studies have shown that Biotin is helpful in giving you your best hair.
Biotin aka Vitamin B7 has taken all the limelight as an important ingredient for healthy hair. It is a water soluble vitamin also known as Vitamin H where H stands for “Haar und Haut,” the German words for “hair and skin.”
When our body becomes deficient in Biotin it leads to thinning of hair thereby leading to hair fall. This can be explained by the fact that Biotin helps in the production of keratin and helps in hair follicle growth.
Are there any studies to prove that Vitamin H is actually Vitamin for Hair?
Yes there are!
It has been found that supplementation of biotin has shown a positive effect on hair loss. 
About 18 reported cases of improvement in hair and nail health among deficient subjects have been observed when supplemented with biotin.
Uncombable hair syndrome is characterized by dry, blonde, unruly hair with tangled appearance. In the case of subjects with uncombable hair syndrome, a particular study has shown that providing 5 mg/day of oral biotin showed improvement in the appearance of their hair. 
Patients undergoing Laparoscopic Sleeve Gastrectomy (LSG) tend to have temporary hair loss. Biotin supplementation with 1000 mcg/day for 2.5 months was given even though their biotin levels were normal. It was found that 11 out of 29 showed reduction in hair loss. 
Indeed there are studies proving that Biotin can be a solution for balding. It must be kept in mind that it cannot be stored in our body for a long time. If you want to see the difference in your hair volume then the best way to supply biotin is through consumption.
