This area has a number of salons like this one and they all charge around the same prices for their services.
I washed & styled my hair here once. I have really long hair and wanted to straighten it for a dinner thing I had to attend. I had a good head massage while they were washing my hair. They did a good job and I paid $20 in total. But the true test was to see if my hair would start straight the whole night.
I was out until the next morning and because of perspiration, my hair had begun to curl near the roots. It did not look pretty. It did however stay straight for most of the night so the stylist did a good job, but I have had experiences with other salons which left my hair straight from root to end until I washed it, so for me it was not up to standard. Yes, I know I am a diva.
