。
Would you like me to even out the ends?
Literal
Hair-tip [object-を] match-up [emphatic-question-ますか].
A standard hair-salon line. 毛先 ('hair tips, ends of hair') is a compound noun. そろえる ('to put in order, to make even, to align') is transitive; here it's used for trimming the ends so they're at the same level. The bare question form with か (no の) gives a neutral, professional tone.
