I have been to Xotic Hair several times for my hair extension. Depending on who you get they can be very good, although I have had some times where I've had a different hairdresser and they completely have ruined my hair to the point having to let my scalp rest for months after getting them taken out because of large red blisters of had on my scalp from extensions pulled far to tight, I have had a lot of hair loss along with them being applied poorly. This hasn't stopped me going back there however as the price is great and when they're done by a good hairdresser they are done right and really natural looking.
Over all the salon is definitely lacking a professional approach. The hair dressers have no professional manner and do not mind swearing in front of clients. They often talk about thing that should really be kept outside of work.
