Several important factors are taken into consideration before deciding on how many sessions of hair transplant are required. These include determining the area to be covered that depends upon the stage of hair loss a patient is in; i.e. if it is the initial stage, intermediate stage, or the advanced stage. After the area is determined, next pivotal stage is to decide the number of grafts needed to cover the area. You may use our graft calculator to estimate the number of grafts your condition requires. Another important aspect is; if we can harvest the required number of grafts from your head alone, or do we need to go for other parts of the body for the donor.Apart from these important aspects, the characteristics of your hair, the density that you desire,the complexity of the procedure,and your budget cumulativelydetermine the number of sessions you will require. If it is a front and corner recession, it might take less number of grafts and a single session; however, if the hair loss is in an advanced stage, the surgeon might need to first reconstruct the hairline to establish a permanent frame to the face and cover the frontal area in the first session and wait for a few months for the next session. The gap of 10-12 months is given to check for the growth of the first hair transplant and to notice the texture, length, and diameter of the hair after the hair transplant and once the hair has reached the styling length, the doctor can make an appropriate aesthetic judgment for the next session.
