So, I'm sweating a LOT right now. All day long at work it's hot and humid and I can be almost dripping in sweat at times. And then I also take 2-3 dog training classes a week where I'm again working in a very hot, no air circulation environment, sometimes doing a fair amount of running so I'm sweating then. As well as other times I may be out in the heat. My skin under my hair at the back of my head is not enjoying this (nor is my skin all over, but especially under my hair) and I'm thinking that a bit of an undercut would help my skin there by letting more air flow over it. But I never go to the hair stylist. I haven't gotten my hair done by a pro in... 3 years? 99% of the time it's in a pony tail so I don't have to care too much about how great it looks. But since it's almost always in the pony tail if I DID do an undercut it would be on show, so can you do a simple undercut yourself and have it turn out ok? I'm a dog groomer so I know how to handle a pair of clippers, but not behind my head. I also hear growing it out is a huge pain, which I can imagine. Any thoughts?
