- How does cetirizine reduce inflammation linked to hair loss? Cetirizine is proposed to lower prostaglandin D2 and raise prostaglandin E2 around hair follicles; three small trials of a compounded 1% topical report modest increases in hair density and shaft thickness, with minoxidil doing better head-to-head. Topical cetirizine is off-label and unapproved for hair loss, and the evidence is too thin to call it effective or safe.

- Is hydrocortisone effective for stopping inflammation that blocks hair growth? Sources describe hydrocortisone as a short-course treatment for scalp inflammation such as seborrhoeic dermatitis or eczema, and no verified trial tests it as a hair-regrowth treatment; the corticosteroids used for alopecia areata are the potent prescription ones, and prolonged use of any topical steroid on the scalp risks skin thinning.
