Hello all SBG's! I am 26 and NOT balding- but I have an issue I would appreciate feedback on

For several years, since late high school, I have been cropping my hair down to a 2 or less and letting it grow back to over an inch. This has been a decent setup, but within the past few years I have seriously considered shaving my head every time I cut my hair.
Here is my issue:
As my hair grows longer, I seem to develop an increasingly severe dermatitis, to a free which will cause me to itch (disgusting alert) reasonable size chunks of my scalp off and on occasion bleed from doing so. When I cut my hair down, the problem is t eliminate completely, but seems to dramatically improve.
Has anyone had this issue or decided to go bald BECAUSE of scalp problems? My hope is that a regimine of exfoliating and moisturizing a bald me will clear up my issue. Any help, again, would be greatly appreciated!
