When it comes to your locks, thicker and fuller hair might be one of your #hairgoals. It's one reason why people flock to anti-thinning shampoos and take their daily dose of vitamins. While there's no way to magically change the volume of your hair, there are ways to help improve your hair quality and give it a much thicker appearance.

Enter The Ordinary Multi-Peptide Serum for Hair Density. It's one of the more popular hair serums floating around TikTok and for good reason. It's made to promote thicker, fuller and healthier hair as the serum contains three noteworthy ingredients — rendensyl, procapil and baicapil. Together, this trio is designed to support hair growth and density.

Procapil, in particular, helps increase blood circulation to the scalp which allows hair follicles to receive more nutrients. As a result, this process can help pave the way for thicker hair.

Paying attention to the condition of your scalp is important if you want to have healthy-looking hair. According to a 2018 study, hair growth and retention can greatly be impacted by the condition of your scalp. For example, if your hair follicles become inflamed due to a fungal infection, this can lead to some hair loss, according to Medical News Today.

While minoxidil and finasteride are the only FDA-approved treatments to help hair loss and hair thinning, The Ordinary serum has received high marks from reviewers.

"Was a bit worried about adding oil to my scalp after washing and drying my hair," one reviewer said. "Was amazed at how easy it is to apply, and my hair definitely looks thicker and healthier."

Another buyer echoed a similar sentiment: "I've been using this serum for about six months and have noticed major effects. I feel a lot of new hairs are growing, which is making my scalp look full. Looking forward to seeing the changes after a year."

However, not all reviewers experienced such major results.

"My hair feels healthier and denser," one reviewer wrote. "It also helps with smoothness. Don’t expect any drastic changes in hair loss though, it only helps pre-existing hair look better."
