The price of hairline planting is the same as the price of hair transplantation, which is calculated according to the number of hair follicle units * the unit price of hair transplantation technology. The number of hair follicle units to be planted in hairline is small, and the unit price of hair transplantation technology is generally 10-20 yuan.

Therefore, the price of planting hairline ranges from several thousand to more than ten thousand.
