- 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.
JAK inhibitor that reduces inflammation and immune attacks on hair follicles, leading to potential hair regrowth, especially in alopecia areata cases
signaling protein that, when suppressed, may grow hair by reducing inflammation and stem cell loss
laser therapy for anti-inflammatory and likely insignificant hair regrowth effects
a JAK inhibitor for alopecia areata and other autoimmune conditions
acid used for antimicrobial, anti-inflammatory and anti-androgenic properties
- 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.
