We color my hair at home so no problem there, although I'm thinking of just letting my gray grow out. I cut my bangs myself so no problem there either. I actually trimmed the ends the other day, it's long so I figured even if it was uneven you wouldn't really notice. Just this morning my honey had his extra beard trimmer out reading the directions to see if it could be used to cut hair just in case I had to trim his (boy would that be a disaster) and if we need to use it to trim the dog. She is the biggest problem, she gets groomed every 6 weeks or so, she is a Yorkie and we keep her in a puppy cut instead of that long yorkie cut. We did trim her bangs and around her mouth and bottom the other day. Gonna get interesting soon.
