Chinese researchers coated cerium nanoparticles with a biodegradable polyethylene glycol-lipid compound as an innovative way for androgenetic alopecia (AGA) treatment.

They made the dissolvable microneedle patch by pouring a mixture of hyaluronic acid — a substance that is naturally abundant in human skin — and cerium-containing nanoparticles into a mold, according to the Science Daily.

The team tested control patches and the cerium-containing ones on male mice with bald spots formed by a hair removal cream. Both applications stimulated the formation of new blood vessels around the mice's hair follicles.

However, those treated with the nanoparticle patch showed faster signs of hair undergoing a transition in the root, such as earlier skin pigmentation and higher levels of a compound found only at the onset of new hair development.

These mice also had fewer oxidative stress compounds in their skin.

Finally, the researchers found that the cerium-containing microneedle patches resulted in faster mouse hair regrowth with similar coverage, density, and diameter compared with a leading topical treatment and could be applied less frequently. Microneedle patches that introduce cerium nanoparticles into the skin are a promising strategy to reverse balding for androgenetic alopecia patients, the researchers say.
