There’s a new ingredient that’s gaining attention in the beauty world: hyaluronic acid. While this substance is commonly used for skincare, it’s also fantastic for hair health. We’ve compiled all the info you need to know about hyaluronic acid for hair so you can make an informed decision about your haircare options.

What Is Hyaluronic Acid, and How Does It Benefit Hair?

Hyaluronic acid — also known as hyaluronan or hyaluronate — is a substance naturally found in the body that provides moisture, lubrication and elasticity to various tissues, including the joints, eyes and skin. It can also be made synthetically and used for medical and cosmetic purposes.

A powerful humectant, hyaluronic acid draws moisture from the environment and locks it in. When applied directly to the scalp and hair, this translates to:

  • Softer, shinier-looking strands
  • Reduced appearance of frizz and flyaways
  • Enhanced moisture for dry, flaky scalps
  • Improved efficacy of other hair products
  • Thicker-looking hair

These benefits may be particularly advantageous for individuals who’ve experienced age-related hair thinning. Hyaluronic acid levels in the body naturally decline over time, leading to a reduction in the hair’s ability to retain moisture. Supplementing this substance through the use of hyaluronic acid hair products can help restore your tresses’ youthful appearance.

The Best Ways to Use Hyaluronic Acid for Hair

Hyaluronic acid is added to a wide range of hair products, including shampoos, rinse-out conditioners and leave-in products such as curl creams, detanglers and leave-in conditioners. Although using a shampoo or rinse-out conditioner containing hyaluronic acid can’t hurt, it’s best to use a leave-in product such as hyaluronic acid serum for hair, which will allow the hyaluronic acid to stay in contact with your strands for a more prolonged period.

If you opt for a leave-in product containing hyaluronic acid, be sure to apply it soon after a shower while your hair is damp. Wet hair is more receptive to products, allowing the hyaluronic acid to penetrate the hair more deeply and work its magic. You’ll also get better results by applying the hyaluronic acid product before other styling products and layering it with a lightweight oil or serum.

You may also benefit from using hyaluronic acid in your hair as a pre-shampoo treatment. Before shampooing, apply a generous amount of the product — either on its own or mixed into a dedicated pre-shampoo treatment product — to your scalp. Massage it in with your fingers using circular motions to ensure even coverage, and then leave it in for approximately 30 minutes before washing. If your hair is especially dry, you may benefit from leaving it in overnight.

People with all hair types can benefit from using hyaluronic acid on their hair, and there’s no limit to how often you can use it. By adding hyaluronic acid products to your usual haircare regimen, you’ll get the most out of the ingredient’s unparalleled hydrating properties.
