Is it possible that oral min has an impact on prolactin levels and erectile dysfunction? I swear I started developing symptoms only on oral min and no fin, not able to sustain an erection.

Yes, minoxidil can increase prolactin levels in women and impact their menstrual cycle. From what I read, it has no impact on testosterone and there are no reports that it can cause sexual dysfunction in men. In fact, the vasodilatation associated with minoxidil may be a reasonable treatment for erectile dysfunction according to some reports.  Maybe you are having a placebo side effect?

Both sides have identical recession as shown here. 

Assuming that you just want to fill in the corners and create a normal mature hairline, and assuming that your hair is at least medium in thickness in the back of your head, it would take about 1500-1700 grafts, depending upon where you and your surgeon place the exact location and shape of the hairline. A coarse, hair will drop the numbers while fine hair will increase the numbers. I have been doing hair transplants for 32 years and adjust the graft numbers to the donor supply, the balding pattern, the donor density the donor hair thickness and getting to know the patient and his expectations, so even the above estimate may change.

In my weekly MIT Review, the following statement was found:  “Since the 1980’s, there have been few advancements in treatments for hair loss and thinning.  Thanks to Revela’s proprietary new search engine, we now have a revolutionary new formulae. The Secret? The worlds first new molecule, discovered by AI, to help encourage follicle health regardless of the cause of hair loss. ProCenilyl ™, helps activate dormant hair follicles to stimulate growth. In clinical trials, 97% of users saw fuller hair and brows in as little as 6 weeks. Just message a few drops into your scalp, it is that simple.”  

I never heard of this before, so I am a doubter as this was a sponsored advertisement.  

I want to start going to the gym but I heard that doing exercice can accelerate my hair loss and therefore making the finasteride useless.. Is that true or can I start going to the gym?

Exercise all you want while on finasteride. No problem

This man’s photos shows two problems.  (1) above the scar, there are areas of balding which indicate that the scar will become obvious, and (2) the stitches were placed far back creating a railroad pattern which will (a) cause hair loss and )b) probably keep elements of this scar.  This man will need a hair transplant to fix this once it is healed.  Why would any man do this when a hair transplant alone would have solved his hairline recession?

The crown often responds to finasteride alone in men under 30 as shown here
