Biotin
The evidence for biotin’s ability to promote hair development on its own is scant and inconclusive, but it is slightly more potent for its ability to stop hair loss. But only those with a biotin deficiency are likely to benefit from biotin supplements to prevent hair loss and promote growth.
In one study, 38 percent of the women who reported hair loss had a biotin deficiency. In addition, 11 percent of the participants had a history of a deficient risk factor, such as IBD, or the use of certain drugs like antibiotics, such as inflammatory bowel disease. This study shows the connection between hair loss and low biotin levels, even though it didn’t examine the impact of biotin supplements or hair products with added biotin on preventing hair loss.
In cases where a biotin deficiency isn’t the cause of hair loss and thinning, supplementing with biotin without first identifying the cause can obstruct or delay the proper course of treatment. Biotin supplements cannot always be effective at preventing hair loss, even in circumstances where a biotin shortage is present. In some people, treating a biotin deficit with supplements can stop hair loss because it is occasionally linked to this condition.
