Associação da fotobiomodulação e microagulhamento na perda capilar padrão feminino, estudo clínico, randomizado, duplo cego

Abstract

The pattern of female hair loss has been defined as progressive miniaturization of the hair follicle with a great impact on quality of life causing significant psychosocial limitations. However, techniques such as photobiomodulation and microneedling have been considered safe and effective resources to treat different types of hair loss. Check if there is an increase in capillary density per area in cm2 when Photobiomodulation with 660 nm red laser and Micro-needling in Female Standard Capillary Loss is associated. The sample consisted of 31 patients divided into G1: microneedling and simulation with a 660 nm laser; G2: 660 nm laser and microneedling simulation; G3: 660nm laser and microneedling. There were 36 sessions, 3 X a week, 3 consecutive months, with microneedling insertion every 30 days. The evaluations included a quality of life questionnaire for women with androgenetic alopecia, Global photography and tricoscopy. 31 women aged 37 to 51 years participated in this study. At the end of the treatment, the score was for total wire density for G1, G2 and G3 (-10 nm / cm²), terminal density G1 (-30 nm / cm²), in G2, (- 10 nm / cm²), G3 (- 70 nm / cm²), density vellus G1 (2 nm / cm²), G2 (-4 nm / cm²), G3 (2 nm / cm²), for total diameter G1 (-2 m), G2 (0.0 m), G3 (1 m), terminal diameter G1 (-1 m), G2, (1 m), G3 (1 m), growth rate G1 (0.03%), G2 (-1 %), G3 (0.09%), anagen threads G1 (8%), G2 (1%), G3 (0.0%), the statistical analysis showed p> 0.05, for all groups, in none of the variables were significant, except for quality of life, considering the variation of the total scores, in group 1 the variation was 19 points (41-22), in group 2 it was 14 points (43- 29) and in group 3 it was 45 points (64-19). It is concluded that the association of the techniques does not seem to have an additional effect to improve the total density of the threads, that is, FBM and microneedling or the association of both techniques maintained a score without significance after 36 weeks with p> 0, 05. However, all treatments showed improvement in the participants' quality of life.
