Hi Randy,
Are you considering a frontal partial (goes in front of your own hair) and keeping your own top hair? Or will you be getting a topper that covers the top of the head? Your markings look good. You’ve marked a hair line that looks very natural. And I think your specs will work well and blend with your own hair. If you are considering a topper (for newbies that a term used for a hair system that covers the top of the head) you would need to shave your top hair. Two reasons for this. First, if you leave your own hair on top it will show through the base. The bases are translucent and allow the color of your scalp to show. It there is hair that is matted down under the base it will be visible--not good. The second reason is that you need to attach to skin in order to get a solid bond. If hair is in the way the bond will not be secure. But overall you did a great job of outlining the base and selecting specs. Your new hair will look great!
Regards,
John
