It is to be expected for a white male in his early 20s to have some temple recession. The problem is when the recession keeps receding and your top and crown also start thinning. Right now it looks FINE but could always change. If you have a lot of male pattern baldness in your family and you are noticing thinning in other areas I would contemplate treatments--you can start with minoxidil for now and see how things go. Adding a derma roller can also help along with regular, vigorous scalp massage. If you are noticing fast thinning, then I would also add Finasteride.
