Is minoxidil sufficient to retain hair after PRP without maintenance?

Both finasteride and minoxidil help with retaining hair and can be used together and- in conjunction with PRP.Based on your history of pcos, it would be beneficial to be seen by an endocrinologist to treat your vitamin deficiencies and hormone fluctuation.  There are a variety of medications that are available for pcos.Good luck!In good health,Ellen Mahony, MD

In my opinion, minoxidil will not maintain the positive effects of PRP. You should consider using spironolactone, progesterone or low level laser as a alternative. It is not a replacement. Spearmint tea and metformin  has also shown to be effective with PCOS. Find a hair expert.PRPHAIRMD.COM 

This requires an in-person evaluation. I suggest seeing a hair loss expert now to evaluate and go over your condition and provide you information about your best treatment options and supplements. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

It appears as if the effects of PRP are short-lived (e.g. 3-6 months) so it would be best to continue Minoxidil indefinitely as a maintenance medication.I would check with your doctor regarding other possible treatments(e.g. Spironolactone for PCOS).

Minoxidil and PRP work differently so you can use both at the same time. One is not a substitute for the other. The benefits are additive. Minoxidil works well in perhaps 40% of patients and even then may only work for a few months. It's benefits may cease at some point. PRP works well in over 90% of patients with androgenetic alopecia but like everything in hair treatment, also needs maintenance every 6 months or so. Stopping both will likely result in a reversal of benefits. You definitely should take Vitamin D supplements and iron as well, as both of these are associated with hair loss. So the bottom line is to take the Minoxidil for as long as it is effective. Once it stops working, you might try Low Level Laser Light Therapy as this is the least expensive treatment (after paying for the unit) and works in perhaps 35-45% of patients.     

No, one does not replace the other. They work though different mechanisms. Additionally if you have hormonal changes, consider anti-androgens by a Specialist. Your hair loss can be slowed down, regrowth achieved, but you will need to be on different medications, PRP is only one part of the answer. See a hair expert or endocrinologist before PRP injections.
