Due to the difference of individual differences, the hairline height is different, some hairline hair is born thin and sparse, long not long, difficult to comb, the hairline shape is not clear. There are also some people who are often forcefully combing their hair upwards and backwards to tie their hair, causing the hairline and the hair on both sides of the temple to be damaged and fall off, appearing extremely sparse and exposing the scalp. There are two specific cases: 1, if the hairline is too low, too much hair, you need to solve such symptoms by hair removal, laser hair removal after delineating the desired hairline, treatment every 4 weeks or so, generally need to treat 3-5 times. 2, if the hairline is too high, you need to change this phenomenon by hair transplantation, after designing a suitable hairline, extract hair in the back of the occipital area and plant it in the designed hairline area, the procedure usually takes 4 hours. Currently, single hair follicle extraction is commonly used and generally leaves no scarring after the procedure, and the best results are most evident in 10-12 months after the procedure.
