What to ask for
Color work—especially highlights—needs someone with a steady hand and a sense of dimension. When you call or book online, mention the look you're after: dimensional, subtle, bold. Ask how long they've been doing color and whether they do consultations. Most salons here offer the service alongside cuts and styling, so you're not hunting for a one-trick shop.
The local picture
Eight salons in Columbus offer highlights. All eight are rated—average comes to 4.9 stars across the group. About 62% offer online booking, which saves a phone call if you prefer it that way. The spread of reviews runs from 9 to 309, so whether you want a newer salon or one with a long track record, both options exist here.
How to choose
Check the salon's Instagram if they have one—color work shows well in photos, and you'll get a sense of their style. Read a few reviews focused on color, not just overall experience. If you find someone whose work resonates, book it. Most won't charge you for a consultation, and a good one is worth the time.
