The story goes that if you’re looking for a product to make your hair thicker and fuller than ever before, you should reach for Capixyl. Because it targets the overall health of hair follicles, Capixyl aids in eliminating all the causes of thinning hair as well as encouraging new hair growth. So, whether you have a receding hairline or want thicker hair, you should put a Capixyl product on your radar. No worries. After reading this article, you’ll know what Capixyl is, what it does to your hair, how effective it is, and what are the best Capixyl-infused products for hair growth.

What is Capixyl?

Capixyl is a peptide complex (Acetyl tetrapeptide-3) mixed with red clover extract, formulated by Lucas Meyer Cosmetics, a leading innovator in personal care products. Red clover extract is rich in biochanin A, a natural DHT blocker known to support hair growth and reduce shedding by regulating the hormone that damages hair follicles. This compound is often used in hair growth formulas due to its potency to minimize the conversion of testosterone to DHT in androgenic alopecia.

How does Capixyl reduce hair loss?

One of the most common factors that affect the health of hair follicles is elevated levels of dihydrotestosterone (DHT). DHT is a hormone converted from testosterone with the help of an enzyme called 5-alpha reductase and is known to attack hair follicles at the cellular level. Simply put, high levels of DHT can shrink your hair follicles and decrease the growth cycle. As a result, the hair grows thinner and weaker.

Capixyl reduces hair loss by minimizing the conversion of testosterone to DHT. Biochanin A, used in the formulation of Capixyl, is an effective inhibitor of 5-α-reductase activity, reducing DHT conversion. The other compound, Acetyl tetrapeptide-3, stimulates tissue remodeling, increasing hair follicles’ size for better hair vitality and faster growth.

Does Capixyl really work for hair growth?

Estelle Loing, R&D Director at Lucas Meyer Cosmetics, underwent a clinical trial to investigate the compound effect of red clover extract and biomimetic peptides in treating alopecia. By the end of the trial, the hair count increased by +13% due to the inhibition of 5-α-reductase activity. Besides reducing DHT levels, studies have found that Capixyl can reduce scalp inflammation and stimulate the matrix proteins (such as collagen, enzymes, and glycoproteins), which encourage the surrounding hair follicles to produce healthier hair. So the short answer, yes, Capixyl works — reason plenty of cult-favorite products use it.
