GlossaryProstaglandin D2

lipid compound linked to hair loss and inflammation

Prostaglandin D2 (PGD2) is a type of prostaglandin, which are lipid compounds that have hormone-like effects in the body. PGD2 is involved in various physiological processes, including the regulation of inflammation and allergic responses. Notably, it has been linked to hair growth regulation, where elevated levels of PGD2 in the scalp have been associated with hair loss conditions such as androgenetic alopecia.
