Veiled chameleon stuck shed :(

[LizardGurl]

My 5mo veiled chameleon started shedding last thursday and for once hasnt managed to shed the skin on his tail or face. He shed the skin on his lower mouth and his eyes but the large veil at the top and his upper face looks white his tail also hasn't shed.
His humidity is around 50% I'm finding it difficult to keep the humidity higher than that without the eco earth substrate being basically water which isnt good when he keeps wanting to go on the ground and dig or rub his face on the glass walls. He also has a dripper set up and I'm going to go get him a live plant to raise the humidity.
Any ideas what else I can do? He has never taken this long to shed before
Can I use zoo med repti shedding aid? Will it help any?
Thanks

The shedding aid might help, but most importantly you need to make sure the humidity is high enough, and you mist the cage enough. I have an automatic mister set to mist for 15 minutes three times a day.
Also you want to make sure there are plenty of branches and foliage, because they like to rub against them to remove shedding skin. If there is not enough I can see this as being an issue.
What kind of enclosure is it? If it's glass, then maintaining humidity shouldn't be an issue; rather being too humid is what I hear a lot from owners who house in glass enclosures. I have a screen cage 2x2x4 and a couple plants inside and my humidity levels are fine.
Hope this helps

Thanks for replying, yes its glass. It's an exo terra 45 x 45 x 60 he has a large grapevine and a tree root with some fake plants stuck to the glass I also added a bit of cork bark for him when I seen he had issues shedding and he seemed to like it but it hasn't helped any and I'm waiting on a jungle vine I've ordered for him to arrive.
I'm not sure if it changes anything but I'm in the UK and mesh tanks don't seem to be widely used here, I think the humidity might be an issue even in glass tanks?
I've covered half his tank lid with damp kitchen roll and hope this helps him
I usually only mist twice a day and he has had 2 previous sheds with no bother but since noticing his issues I'm misting him basically 5 times a day sometimes directly with warm water but it hasn't helped. :S
