i started going to Martina at clark nova 3 years ago and i won't go anywhere else. she's incredibly "charismatic" (i would use another word but citysearch won't let me)--all of my guy friends who go to her think so, and she's not traditionally "LA". there's just something about her...
plus, getting my hair done there is so much fun! it's seriously a social event every time i go. my friend karen and i often book appointments together and while karen's highlights are setting i get my hair cut and we all just chat and have fun. we've even had small parties there--3 of us once had appointments together and brought mimosas and pastries. and invited everyone to partake!
karen's boyfriend went to martina for the first time and LOVED her! he got so many compliments on his new haircut that he swore he would "never go to supercuts again!" not the most credible endorsement given the source, but greg loves martina as much as karen and i do and he's not easily impressed.
of course everyone else at clark nova is great, but i'm biased toward martina. she's the best :)
Pros: everything!
Cons: parking is hit-or-miss. it's not terrible, but it's LA, people. don't expect to find a spot waiting for you in the front.
