Ya can't really tell man. The only way I notice receding on black men is under bright light starting at the temples going back. Yours doesn't look too bad at all tho. Left temple hair may be getting thinner at this point, but like I said from pics its hard to tell. If you care so much about it, which it appears you do since you are this concerned at very minimal loss if any, just pick up S5 creams day and night and apply them to your temples. Kind of expensive but if you keep them refrigerated a pack can last you 6+ months. Don't do any orals at this point. Topicals for now and after 1-2 years look into finasteride, but I think you are fine.
