I had a scalp micropigmentation done with too much density and too dark black. Best way of removing it? Will laser tattoo work?

lasers may be able to remove SMP or tattoo but you would likely need to shave your head first.  You need to see a doctor for an examination to see if it may work for your case. 

Normally a laser practitioner will want as much information about the pigment and technique as possible. Also many will request to perform a patch test on an area before performing a large area. Q switch or similar are the most common tattoo removal laser machines but mainly used for traditional tattoo pigments. 

It is hard to tell from the photos if actual SMP was done or conventional tattoo. The dots seem quite bigger than the typical SMP dot. If the depth and type of ink used is correct, the a Q switch laser should fade this or even remove it nicely. 

Assuming that the pigments were put into the correct position, the use of a Q switch or similar laser should nicely remove the pigments in a couple of treatments
