You don't need fair skin for laser, YAGs work best on darker skin types, and honestly are probably the most effective method for African Americans.
But you need DARK hair, without question for laser. Laser is not a scam for anybody with Dark hair, in fact it works great, but anybody else...yeah stay far away and go to electro.
I would like to mention. I know somebody going to E-3000, she should have done laser (fair skin, dark hair), her FIRST session was the total of five laser sessions for me (basically the first five, and than maintenance, which is extremely cheap). By the end she will be paying 6 times or more what I will be (because of flights, hotel, etc) for hair removal. So for those who think laser is not cheaper than electro, think again. As far as I see it the money I am saving doing laser which is less time consuming, will result in me being able to afford a bit of FFS I would like. The results...will be identical, except I spend 30 minutes per session and only about 7 hours total by the end and around $2000, she spends hundreds of hours, and thousands more dollars. People wonder why I say if you go to electro if you have laser as an option, its simple math. Transition is expensive enough, why throw more money at something you don't need too. If you have dark hair, feel fortunate and do laser, it really is that much cheaper and it is just as effective, contrary to what some detractors say.
