he may not shed his whole body again for a long time. As they mature they will shed body parts instead of their whole body. There is no set time frame and each chameleon is different.
My baby just shed some skin today... I saw what looked to be really dry spots on the tail... went out and came back about 3 hrs later and its whole body was peeling. My baby managed to get it all off pretty quickly. It was interesting since this is my first chameleon and all.
