Regarding: PRP - How long does it last? How often does it have to be redone?

When PRP is used to promote hair growth, most
patients require repeated treatment 2-3 times per year. Because results vary
from patient to patient, the treatments may need to be continued intermittently
to maintain any improvement. This will depend on, final goals, amount of hair
loss, and patient’s response to therapy. Most patients will see results within
3-6 months.

Thanks for your question, Gerry - In short, the duration of the benefits derived from PRP treatments depends on the nature of the cause of the hair loss, whether it's andro-genetic hair loss in men or female pattern hair loss in women, the benefit is probably temporary since these are genetic conditions which should revert back to the baseline after enough time has passed for the pathophysiologic processes operant in the patient to overcome the hair in the pattern. However, I have had female patients that have had a 2 procedure series, with no re-currence of thinning 3+ years later. Then of course I see patients that have substantial benefit which wanes over-time, they return for "touch up" prp procedures as needed. Dr. Bernardino Arocha, M.D., FISHRS

The answer to this question is not simple. It depends upon the PRP injection protocol. If one uses multiple injections at the beginning of the treatment, it is possible for results to last six to 12 months. However if one only employs a single treatment, longevity may be as little as three months. Some practitioners believe that adding a cell extends the duration of Effectiveness. This has not been proven. A second factor, is age of the patient. Younger patients, with less hair loss and Less dormancy of hair follicles, does not need to repeat the procedure as often. A third factor, is concomitant treatments. If one adds topical finasteride or oral finasteride as well as topical progesterone for women, it is common that the longevity is increased. In summary there is no single answer to your question, seek someone who has experience with PRP.PRPHAIRMD.Com
