Vitamin B3 is also known as niacin or niacinamide, if you’re checking the label on your hair products. A study from the National Center for Biotechnology Information (NCBI) tested the topical application of two niacin derivatives—octyl nicotinate and tetradecyl nicotinate—and found that these derivatives demonstrated a significant increase in the appearance of hair fullness in female alopecia.

Aside from hair fullness, another study from the NCBI found a leave-on technology containing niacinamide resulted in increased hair suppleness and a better ability to withstand force without breaking.

Product pick: If you’re interested in products formulated with niacinamide, we recommend the L’Oréal Paris Elvive Dream Lengths Restoring Shampoo for Long, Damaged Hair. This shampoo for long, damaged hair helps to seal split ends while adding shine, protecting lengths, and strengthening hair. Use as a system with the L’Oréal Paris Elvive Dream Lengths Conditioner for Long, Damaged Hair and L’Oréal Paris Elvive Dream Lengths No Haircut Cream Leave In Conditioner, which are also formulated with B3.


Also called panthenol or pantothenic acidvitamin B5 is another hair vitamin worth taking note of. According to the NCBI, pantothenic acid has been studied for its ability to help prevent early hair graying, restore natural hair color, encourage proper hair growth, and give hair moisture.

Product pick: If you are interested in products formulated with B5, we recommend the L’Oréal Paris Excellence Creme Permanent Triple Protection Hair Color. This permanent hair color kit includes a conditioning treatment formulated with panthenol. Our exclusive Triple Protection System provides rich, radiant color while deeply caring for your hair before, during and after coloring.

Another B vitamin, B9 (also referred to as folate or folic acid) is also a key hair vitamin. Folates help with stimulating the hair follicle cells and regulating sebum gland function, according to the NCBI.


Next on your hair vitamin list? Vitamin E—more specifically, tocopherol, which is part of the vitamin E family. Per an NCBI study, this type of vitamin E is found in Moroccan argan oil, which is known for its ability to keep the hair moisturized.

Product pick: If you’re interested in products formulated with tocopherol, the L’Oréal Paris Elvive Color Vibrancy Protecting Shampoo is formulated with tocopherol. Our Color Vibrancy Intensive system for color-treated hair works to keep hair color healthy-looking and vibrant thanks to a formula with anti-oxidants (UV) and ceramides. Use as a system with the L’Oréal Paris Elvive Color Vibrancy Protecting Conditioner and L’Oréal Paris Elvive Color Vibrancy Repair and Protect Balm, which are also formulated with tocopherol.
