Studysummary This study found that 1% anthralin ointment effectively promoted hair growth in children with chronic, severe alopecia areata, showing complete or partial responses in 70% of participants over 12 months, without serious adverse events. Our plain-language summary of this paper — not a Tressless recommendation.
In a 2017 study involving 30 children with chronic, severe, treatment-refractory, extensive alopecia areata (AA), 1% anthralin ointment was applied to one side of the scalp for 12 months, with the other side left untreated. The Severity of Alopecia Tool (SALT) score was used to assess outcomes. Results showed that the mean time to first response was 3 months, and to maximal response was 9 months. After one year, 10 patients (33.4%) achieved complete response, and 11 patients (36.6%) had a partial response, with 6 of the partial responders eventually achieving complete response. No serious adverse events were reported, indicating that 1% anthralin is an effective and safe therapy for AA in children. The study recommended continuing treatment for at least 9 months, and for those with at least a 50% reduction in pretreatment SALT scores, to continue for at least 1 year.
