What does Vitamin B5 do to your hair?
Vitamin B5, otherwise known as pantothenic acid, works in combination with other nutrients to rebuild the individual hair shafts, which are often damaged by blow-driers or heated hair tools, by shampooing too often or by sun exposure. Vitamin B5 can also help increase hair growth by supporting and protecting the adrenal glands. Increase vitamin B5 in your diet by adding more eggs, avocados, potatoes, beef, chicken, nuts and legumes.
A 2011 study published in the British Journal of Dermatology examined the ability of a leave-on combination including panthenol, the alcohol analog of pantothenic acid, to affect the diameter and behavior of individual terminal scalp hair fibers. The treatment significantly increased the diameter of individual, existing terminal scalp fibers. It also thickened hair fibers and increased the pliability, giving the hairs better ability to withstand force without breaking. (4)
A major sign of a biotin deficiency is hair loss. A deficiency can be caused by smoking, impaired liver function or even pregnancy. Research suggests that a substantial number of women develop a biotin deficiency during normal pregnancy because the rapidly dividing cells of the developing fetus require biotin for synthesis of essential carboxylases and histone biotinylation. Researchers conclude that signifiant alternations in markers of biotin metabolism during pregnancy and breast-feeding suggest that biotin intakes exceed current recommendations in order to meet the demands of these reproductive states.

To reverse hair loss and increase hair strength, take one B-complex vitamin tablet daily or take biotin and vitamin B5 separately. Eating biotin and vitamin B5 foods, such as eggs, beef, chicken, avocado, legumes, nuts and potatoes, also helps you to avoid a deficiency and aid hair growth.
