I hate going in for a haircut. Now my SO doesn't expect much from a cut, just shorter and sorta in a certain style, kinda. Dude last cut I was like what the heck did they do to your hair? I had to go redo it. SO of course thought I was overreacting but when it started growing out it was obvious what I meant.
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
