This is why I now do my own hair at home. No salon, white or black,can get it right.
It really depends on the stylist. You have many in the trade that are out for a quick buck, and you have those who have a genuine interest in keeping their clients and taking care of their hair...I am fortunate to have a stylist in the latter category, who also attends my church. She's been my stylist for at least a dozen or so years.
...As for going to a major department store salon, FORGET it! I made that mistake once with JC Penney back in 1988. Never went back.
