Hyaluronic acid may help promote healthy hair growth. It is believed to act as a fertilizer that conditions the hair and scalp, thus promoting cell rejuvenation. Anecdotal evidence suggests that it stimulates hair growth and thickness.

A research study showed that a blend of hyaluronic acid, collagen, and chitosan helped in increased thickness of the hair strands (2). Thus, it may help add volume to your hair.

As we age, the hyaluronic acid in our body decreases. This is true for the dermal cells surrounding our hair follicles, too. This can be one of the reasons why our hair turns dry and brittle hair as we get older. So, replenishing hyaluronic acid can help in conditioning the hair so it looks smooth and feels soft. This humectant locks in moisture which smoothes cuticles, making the hair strands stronger and less prone to breakage.

Apart from improving elasticity, it can also add shine to your hair as sealed cuticles reflect light evenly!

Thus, hyaluronic acid may help give you longer, thicker, and glossier hair. However, there is no scientific evidence to prove this. Cosmetically, the appearance of the hair would be improved, potentially making it look longer and thicker.
