Thank you for answer. Strangely enough that you directed this term to hair-cutting and the same was other tracks in internet too. But I run in this term in apparel shop company report.

Here’s a use of “trend-right” from the internet that suggests the meaning “not too cutting-edge, not too old-fashioned”, or “in-style, but not overly trendy”: Ask our typical female customer what look they are seeking and they’ll describe a look similar to Jennifer Aniston, the beautiful girl next door. Not out of date, not too risky, just plain beautiful. We call that “trend-right,” and it’s a key part of what makes Fantastic Sams an iconic and successful salon franchise.
