Helmed by acclaimed beauty duo Cary and Talisa O'Brien, Cary O'Brien's staffs an experienced arsenal of hair designers, aestheticians, and stylists. Get a clip and style with a junior stylist ($34), or book a session with a regular stylist ($39).

• Connie at Cary O'Briens is absolutely fantastic! I have never had 'bad hair' when leaving Cary O'Briens! – karenhunter, Citysearch
• I have been going to Cary's for quite some time now and always I feel like a part of a family to the way I'm greeted to the occasional hug. A lovely woman that has 19+ years of experience has been a friend a wonderful hair designer to me and all the girls have soo much training I am never nervous about the new styles they always want me to do. – mymynicegirl111, Citysearch
