Is it better to have ongoing small hair transplant procedures or wait and have fewer larger procedures?
Waiting to have a larger procedure obviously means allowing hair loss to progress to a higher Norwood stage, maybe NW 4 and above; it does have the advantage that there is the potential to cover the entire area of hair loss in one pass. There is the temptation to treat minor loss with a hair transplant; the advantage being that the appearance of hair loss is insignificant, as if you have little to no hair loss over as the person ages.
A concern in treating minor hair loss is generally this will commence with the hair line; and require fixing a permanent hair line design that will never change over time. Age is an important factor if this is the case. Another concern is as you continue to lose hair behind the treated area; patches of thinning and miniaturised hair will appear that will create an unnatural pattern of hair growth or hair loss.
This will require constant small filler or touch up sessions to ensure a natural balance of coverage is sustained, and can result in chasing hair loss on a constant basis, especially if hair loss becomes aggressive. This will result in diminishing the hair available in the donor over time, reducing the total potential amount available due to the changes in the physiology of the skin and hair in the donor area.
With correct planning and on the right candidate even a high NW scale hair loss sufferer (NW5-6) can achieve total coverage with a natural looking density from the hair line to the crown in one procedure. An average candidate may require a second procedure to cover the crown effectively; this reduces the times having to enter both the recipient and donor to reduce the trauma to each area.
Not forgetting the time, cost element involved not having to go through multiple procedures and the inconvenience to your lifestyle and work that will occur. Planning is vital, age, hair loss stage now and potential in the future, hair characteristics, the techniques used are all considerations; so make your decision carefully and with thought.
