Although there is no age matter for hair transplantation, the pros and cons of a transplant need to be carefully evaluated in the younger patients. Patients between the ages of 20-30 years have a stabilized rate of hair loss before they are considered for hair transplantation. A detailed family history is important in assessing hair loss and planning a new hair-line. The color quality and thickness of the donor hair as well as the contrast between the hair and the skin colors are important factors that affect the results. The lesser the contrast between the donor hair and the skin, the better is result. It is noticed that frizzy, curly or wavy hair are advantageous characteristics in transplanted hair, single hair grafts are used to create a natural hairline. The planning of the hair-line is one of the most important steps in hair transplantation. The hairline is the most visible landmark and the quality of work of a surgeon is often judged by the quality of the hairline is the most visible landmark and the quality of work of a surgeon is often judged by the quality of the hair-line. As suggested by Michelangelo, to locate the ideal hairline in a bald patient, it is necessary to divide the face into three equal segments. In the midline, the hairline starts from the 8 cm from glabella. A curve sweeps around lateral side of forehead from the center. On this point, the side of hairline should be oriented parallel to the curve when the subject is looking straight ahead. The lateral hairlines are usually nine to eleven centimeters above the lateral can-thus of the eyes. The patient’s desires and constrains are also other factors that can affect the shape of the hairline. The micro grafts in the hairline should be placed in an irregular saw-toothed pattern of macro-and micro irregularity to give a natural appearance. The patient is asked to shampoo his head with Beta-dine surgical scrub on the day before, and on morning of the surgery.
