Until Sierra, I did not enjoy having my hair cut in a salon. Since my first hair cut with her a year or two ago, I have gone to nobody but her--and referred as many as my friends to her as possible. She is warm and respectful (and FAST, detail-oriented, and affordable!), and does a fantastic job of determining what hair cut and dye will work for me.
I've seen her do amazing cuts and styles on people with long hair, medium hair, and people with short hair--whether those cuts are edgy or more tame. She's helped me grow my hair out from an undercut (without looking ridiculous), taught me how to style it myself, and commiserated with me when I have had to keep the dye jobs tame because of my day jobs.
(and, if you are looking for someone to do a gender neutral cut, a masculine cut on a non-male person, or a super awesome queer haircut, Sierra should be at the top of your list!)
