i would suggest Lulu at Blue Moon Salon in Laguna Mall (opposite Walmart next to the Casino). I have unruly blonde hair and she has been doing my highlights, trims and treatments regularly since July. She is excellent. I'm very fussy with the colours and I'm very happy with Lulu.
I tried another mentioned in this thread and I was far from happy. The colour I ended up with was old-fashioned and made me look 10 years older.
Lulu is Mexican but trained and worked in Canada for quite a few years before coming here and setting up her salon. She is up to date with the latest products and techniques. She also offers OPI manicures/pedicures, massage, waxing etc. You get a nice discount if you get 2 or more services.
Also, if you're like me and never remember to make advance appointments, Lulu will always try her hardest, working extra early or late, to get you in within the week.
