- 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.
signaling protein that, when suppressed, may grow hair by reducing inflammation and stem cell loss
JAK inhibitor that reduces inflammation and immune attacks on hair follicles, leading to potential hair regrowth, especially in alopecia areata cases
laser therapy for anti-inflammatory and likely insignificant hair regrowth effects
a synthetic cortisol used for anti-inflammatory effects
growth factors taken from your blood and injected into your scalp to stimulate hair
