Used minoxidil for a year then stopped gradually, started PRP treatment for at least a year to maintain gained hairs. (Photos)

In  my opinion, it is difficult to predict whether the addition of PRP will counteract the discontinuation of minoxidil. PRP and minoxidil work by different pathways. Hair loss can be multifactorial. I believe the unknown factor is the strength of the genetic hair loss in your family history as well as any other factors that may be determining your hair status. Combining  PRP and minoxidil produces excellent results. I would suggest you consider it. Find a PRP expert who will help with your treatment plan.

Hope this helps.

First, one needs to give thought to the actual diagnosis and then to treatment. While some amount of telogen effluvium could be present here, there is without a doubt a significant contribution from male balding. Minoxidil and PRP work differently and don’t work in everyone. In fact, they perform quite well in a minority of users rather than a majority. If these treatments helped 100% of users one could switch in the manner described without detriment to hair loss. However they do not One needs to be aware that stopping minoxidil (if it were to help) and starting PRP could be associated with hair loss.

Based on your pictures the results are very good. Although PRP is an excellent treatment for hair loss I would not stop the minoxidil.

Since minoxidil and PRP are separate entities once you stop the minoxidil you will lose whatever you have gained by using it. The same will go for PRP, once you stop using it all you have gained will be lost. I would maintain the minoxidil while using PRP for even better results.
