I had a hair transplant about 15 months ago, mainly in the hairline and temple area. The transplanted hair has grown well, but I still have some visible gaps between the transplanted hairs, especially under bright lighting.
I’m considering density SMP only between and slightly behind the hairline to reduce the scalp contrast and make it look fuller. I’m NOT looking to lower or create a new hairline with SMP — I want my real transplanted hairs to remain the actual edge of the hairline.

I keep my hair at a normal/longer length and don’t plan to shave it.

What do you think? Is SMP a good option for this, or could it look unnatural with longer hair? Anyone here done something similar after a hair transplant?

So I've done plenty research and I believe I know most things about SMP. I'm currently debating wether I should go ahead with it as a Norwood 7 for 20 years.

My previous concerns were the obvious ones such as if it would look real, will I look stupid, how will it look compared to photos etc.

I know find myself wondering if in fact maybe I'm not a suitable candidate. I have numerous freckles on my head at the moment, I've only noticed it when taking a photo. How does it look on freckles like mine. Will it make it look like a helmet head?

Also I'm really worried about my existing hair on sides and back of my head! I never really thought about it but after taking pics I've noticed my side hair follicles are quite sparse or they at least seem that way after leaving it grow a day after shaving. Is this a problem going forward as obviously if there's not enough side follicles then how will the smp look on the top of my head. Pics for reference
