Many new treatments have been introduced in recent years. This review summarizes the main ones in 4 groups: a) For androgenetic alopecia, we discuss new excipients for oral minoxidil, dutasteride, and finasteride as well as new forms of topical application; prostaglandin agonists and antagonists; low-level laser therapy; and regenerative medicine with Wnt signaling activators and stem cell therapy. b) For alopecia areata, Janus kinase inhibitors are reviewed. c) For frontal fibrosing alopecia, we discuss the use of antiandrogens and, for some patients, pioglitazone. d) Finally, we mention new robotic devices for hair transplant procedures and techniques for optimal follicular unit extraction.enAlopecia androgénicaAlopecia areataAlopecia frontal fibrosanteAndrogenetic alopeciaDutasteridaDutasterideFrontal fibrosing alopeciaHair loss treatmentsLow-level laser therapyLáser de baja potenciaRuxolitinibTricologíaVía WntWnt pathwayAlopeciaHumansresearch article2806196610.1016/j.ad.2016.11.0101578-2190
