The eyebrows are one of the most important components of the facial structure, and ageing, trauma, and metabolic abnormalities can cause them to fall out or become deficient. In the past, people usually had to choose eyebrow strokes and tattoos to improve the visual effect of the eyebrows, but the “eyebrows” formed by these methods lacked a sense of dimensionality. With the widespread development of FUT and FUE hair transplantation, eyebrow implantation has been gradually recognized and accepted by people, but traditional eyebrow implantation results in thick, hard, sparse and disorganized eyebrows, which is difficult to meet the requirements of beauty lovers. With the continuous improvement of FUE follicular unit extractor and extraction tube, transplantation method and surgical design, FUE eyebrow reconstructive surgery has developed from the original scarred surgery to the current real eyebrow transplantation without surgical traces —- No-scar ultra-precision FUE eyebrow reconstructive surgery, which is summarized by me in the long-term clinical accumulation and continuous study. It consists of four main parts: three-dimensional eyebrow design, selective hair follicle extraction, fine separation method of hair follicles, and fine non-invasive transplantation method. The inner diameter of the extraction tube of the FUE extractor is less than 0.6mm, leaving no scars after the operation. For patients with eyebrow tattooing and eyebrow washing, congenital sparse eyebrows, scarred eyebrow defects, scleroderma with eyebrow defects, etc., 300-450 hairs are needed for women and 400-550 hairs are needed for men, and the highest density is 100 hairs/cm2. In about 21-45 days after the surgery, the transplanted eyebrow hairs start to fall off gradually, and the rate is 50%-70%; 2-2.5 months after the surgery, new eyebrow hairs start to grow; 6-9 months after the surgery, the transplanted hairs basically grow out, and the appearance is very satisfactory; one year after the surgery, the survival rate can reach more than 90%. The results show that the natural appearance of eyebrow reconstruction after surgery is more advantageous than traditional eyebrow transplantation.
