- Abstract: Objective To investigate the clinical efficacy and safety of 1 565 nm non-ablative fractional laser combined with topical minoxidil and oral finasteride in the treatment of patients with androgenetic alopecia(AGA).Methods Seventy-five male AGA patients with Norwood-Hamilton classification grade Ⅱ-Ⅲ,were randomly assigned into three groups:the control group 1,the control group 2 and the experimental group,with 25 cases in each group.Patients in the control group 1 received topical 5%minoxidil(1 mL,twice daily).Patients in the control group 2 were treated with both topical 5%minoxidil and oral finasteride(1 mg,once daily).Patients in the experimental group received a combined therapy of 1 565 nm non-ablative fractional laser in addition to topical 5%minoxidil and oral finasteride.Hair overall efficacy was evaluated using a 7-point rating scale after 24 weeks of treatment.Hair diameter and density were measured using a dermoscope.Patient satisfaction was assessed post-treatment,and adverse reactions were recorded.Results The overall efficacy of hair in the experimental group was superior to the control group 1 and the control group 2.There were no significant differences in hair density and hair diameter before treatment between the three groups(P＞0.05).After treatment,hair diameter and density increased in all three groups compared to baseline values(P＜0.05),and the hair diameter and hair density of the experimental group were higher than those of the control group 1 and the control group 2(P＜0.05).Patient satisfaction in the experimental group was higher than that in the control group 1 and the control group 2(P＜0.05).Patients in the experimental group experienced tolerable pain and burning sensations during laser treatment,and the symptoms were self-alleviated within a few hours.There were no serious adverse reactions reported in any group.Conclusion The combination therapy of 1 565 nm non-ablative fractional laser,5%minoxidil,and finasteride demonstrates significantly better efficacy in the treatment of AGA than minoxidil and finasteride alone drug therapy.
