B-vitamins are popular, water-soluble hair nutrients that support healthy red blood cells. They promote healthy tresses by carrying oxygen and nutrients to cells, including to the scalp and follicles, without which hair cannot grow.
Biotin is the most recognizable of the Bs and it plays an essential role of forming the building blocks of healthy hair. It actually helps to stimulate keratin production and support future hair growth. In fact, many
studies link biotin deficiencies with hair thinning.* While biotin steals the show, there are others that are beautiful hair must-haves, such as niacin, B6 and pantothenic acid.
How B-vitamins rescue hair: Biotin, niacin (b3), B6 and pantothenic acid (B5) support thicker, fuller hair growth by boosting blood flow to the scalp and hair follicles. They quite literally breathe life and energy into the cells that support strong hair growth, stimulating a healthy growing environment in the process.
If you blow dry or straighten your hair, or enjoy spending time under the sun, pantothenic acid also works to rebuild the hair shaft, helping to repair damage.
