Brief Summary

Microneedling and autologous concentrated growth factor (CGF) have established their potential effect in inducing hair regrowth. No study has compared the effect of microneedling and CGF in the treatment of female androgenetic alopecia (AGA).

Interventions

microneedlingPROCEDURE

The microneedling technique (Electric microneedle, F6, China Bohui Meicui Bioengineering Technology Guangzhou Co., LTD.) performed in the targeted areas using a sterile micro needles stamp. In this study, the needle length was adjusted to 0.7\~1 mm according to the grade of hair loss and the degree of tolerance of the patient. Before microneedling treatment, the scalp was disinfected with 75% alcohol, and then 1 ml of nutritional dressing for the scalp was applied externally, and the microneedle pen was gently touched to the scalp vertically for pricking. Patients are instructed to refrain from shampooing, warm baths, and strenuous exercise for 8 hours after treatment. Each patient was treated by microneedling once every 2 weeks for a total of 12 treatments.

microneedling

1. 27\~36ml of autologous venous blood is collected in a sterile Vacuette tube without anticoagulant solution, and centrifuged by Medifuge variable speed centrifuge (Silfradent company, Italy) for about 13min (accelerated for 30s; 2700 r/min, 2 min; 2400 r/min, 4min; 2700r/min, 4min; 3300r/min, 3 min; decelerated for 36s to stop). The lowest layer retains 2.5ml of CGF per 9ml of venous blood. 2. The scalp is cleaned, disinfected and anesthetized, CGF is extracted with a 2.5ml syringe, and the disposable sterile needle roller handle is slowly rolled in the hair loss area, and the CGF is applied to the corresponding scalp part for introduction treatment while rolling, and the force is uniform and stable, repeating back and forth several times, to the extent that the patient can tolerate and the skin in the treatment area is slightly red. The operation time is about 15\~20 minutes.
