Extraction of hair follicle tissue: Hairline adjustment surgery needs hair materials, which come from the beauty seeker himself. It is necessary to extract the healthy hair follicle tissue of the beauty seeker's head by surgical technique before operation. Before extraction, beauty seekers should undergo local anesthesia and then extract hair follicle tissue.

Culture of hair follicle tissue: the extracted hair follicle tissue is not directly planted, but cultured and separated into more quantities in a Petri dish. This process requires the doctor's speed ability, which will directly affect the postoperative effect.

Hair transplantation: The cultured hair follicle tissue is planted in the scalp under the hand of a hair transplant doctor, and each hair should be kept in the same direction, and a proper distance between the hairs should be ensured, which will affect the postoperative effect.
