What's an opinion about hair removal in men and male teenagers?

Laser Hair removal: Lasers can be used to kill the hair follicles. The lasers only effectively treat darker colored hair (blond hairs don't do well with laser hair treatments). The treatment will remove all the hairs at the time of treatment but will only permanently remove the hairs which are in their "growth" phase. This is about 20% of hairs at any time, so usually 4-5 sessions are needed for complete removal.

Great: I think it can be great for guys with excessive hair. The nice thing about laser removal is that you can have the number of treatments that leave you with the amount of hair that you want to remain. Many men do not want to remove all the hair just cut it down significantly. Of course, if they want it all gone this can be done too.
