Laser hair removal works well on people who have dark hair, and light skin. The laser targets melanin... so the darker the hair and the lighter the skin the more aggressive the treatment can be without burning skin too. So the number of treatments will depend upon your set up. It is much faster than electrolysis. Cost will depend upon the size of the area treated. You won't need to grow the hair out long to get an idea of cost... just stubble will be enough to see the area needed to treat. I did lasers to my legs, as I worked at a place where I had access to lasers for free. I have gone from a person who needed to shave maybe twice daily to a person who needs to shave about once every 2-3 weeks, and what grows in is very fine and light. To pay for the entirety of my legs would've been around 1000.00 per treatment and the number of treaments would've been maybe 8-10. Usually quotes for cost from laser treatment centers are free.
