Hyaluronic Acid for Hair Growth: Does It Work?
Hyaluronic acid (HA) or hyaluronan is found naturally in our eyes, skin, and bone joints. This clear, gooey substance is hydrophilic (water-loving), so it attracts water and keeps your tissues moist and lubricated. Research says just one gram of hyaluronic acid can bind up to 6 liters of water (1)! Thus, it is known as nature’s moisturizer.
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.
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.
