I'm curious about scalp tattoo!

My crown is too shiny... While looking into various options, I heard there is also scalp tattooing!
From the reviews, it seems the effects are really good..

Has anyone tried it before? I'm curious about how long it lasts, whether it hurts, and other details.

I want to try it once, but I've never had a tattoo before, so I'm really scared lol

I haven't tried things like eyeliner or eyebrow tattooing before ㅠㅠ Won't it be expensive too ㅠㅠ
