Im 22 years old and Ive been noticing a decrease in hair density over the last 2-3 years. I had recently shaved my head at the suggestion of my barber to assess the situation better, and I found that things were worse than expected. I've been to a dermatologist and they told me to take some blood tests before starting in PRP treatment. Could someone help me understand whether that would actually help? Or is minoxidil the only solution I have (don't want to start finasteride due to the side effects). And could you also give your opinion on how bad the hairloss is at the top/sides? I seem to be having very little frontal recession but just overall loss of hair density. I was also not eating healthy over the last 4 years (only junk food and skipping meals every now and then), but I've started eating better and taking some biotin supplements too.
