H Bluemist,
Your story is a typical one. Guys start losing their hair and they go for a concealer to cover the thinness. It works for a while but it’s messy and they wake up in the morning finding a lot of the concealer on the pillow. It’s a short term fix. But the hair keeps on thinning out and the concealer doesn’t cover as well and it’s gets to be a pain using it. You’re lucky in that you’ve got nice thick sides. So a full hair style like the photo will work well for you. From the photos it looks like you would need a single piece that goes from the crown area to the front hair line. There is some finer hair on the very top but it’s too thin to work with the look you’re going for. That look is entirely possible for you. Making a template is easy but if you feel you need help I think I can find a stylist in your area to help you.
Regards,
John
