So that photo isn't of him currently? (if so, I'm glad)
As for why this happens, it's likely a combination of factors, & you need consider all of them, & fix anything that needs fixing.
-cage humidity not adequate and/or drinking water unavailable; enclosure over-heated (snake cannot avoid the high temperatures- what is your temp. range, hi & low?)
-feeding while in shed cycle (digestion requires good hydration...so does shedding...some snakes do not "multi-task" very well, so it's best NOT to feed them if in shed cycle)
-poor overall health (how long have you had this snake? it may be from previously poor care, poor nutrition)
-parasites (internal, ie. "worms", or external, ie. mites) all steal nutrition & water from a snake's body, leaving them with poor growth & trouble shedding (check for mites, get his stool tested)
yeah it’s probably the 3rd one ive had him for like 2 months now but that was his first shed with me... shortly after taking that picture i got to work and removed his shed
