Vitamin B2(also known as riboflavin): This vitamin plays a key role in fat, protein and carb metabolism. A riboflavin deficiency can result in severe or gradual hair loss.
Vitamin B5(also known as pantothenate): This vitamin is commonly found in various skin and hair care products. A pantothenate deficiency can result in hair loss and scalp irritation. Some hair care experts believe that vitamin B5 can be applied to hair externally to make it shinier and stronger. For this reason vitamin B5 is commonly found in hair shampoos and conditioners, although there is no strong evidence showing that B5 applied externally has any measurable benefits (and if it does they are likely to be very short lasting).
Vitamin B6 While this vitamin is not linked to hair growth directly, it can help to keep your skin and scalp healthy, which will in turn promote better hair growth. Vitamin B6 deficiency can bring on a skin condition called dermatitis which is often responsible for slower hair growth and thinning.
Vitamin B7 (also known as Biotin): One of the main ingredients in hair and skin care products, Biotin is thought to make nails and hair grow stronger. Overall Biotin is an extremely important vitamin as it is required by the body in order to produce fatty acids and promote cell growth. Although Biotin deficiencies are rare, they do happen and can cause hair loss, thinning and breakage.
Vitamin B12 Just like with vitamin B6, B12 has no direct link to hair growth. With that said, without B12 the body cannot perform many metabolic functions which can have an indirect negative effect on hair growth and your overall health. Gray hair at an early age (under 30 or so) can also be a sign of vitamin B12 deficiency.
