I am looking for a good place for scalp tattooing to increase the density on the crown of my head!!

I was getting stressed because the area where my parting is looking increasingly sparse, so I ended up looking into scalp tattoos. I heard that dotting can smudge or look unnatural if done incorrectly, so I want to be really careful in choosing a place that does it well. Does anyone know of a place that does scalp tattoos well and delivers natural-looking results? It would be a huge help if anyone who has had the procedure done could share a good spot!!!
