Shops that get a lot of fresh 5-star reviews get seen first on Google Maps. When someone nearby searches for a barber, the shop with the freshest reviews is usually the first result — and freshness matters as much as the total. A shop with 400 old reviews can sit below a shop with 150 that's earning new ones every week.
One rule before anything else: never buy or fake reviews. It violates Google's policies, reviews get removed, and profiles get penalised. Everything below gets real reviews from real customers.
Free, and it works when it happens. The problem is that it stops happening: chairs get busy, asking feels awkward, staff forget. Almost every shop that relies on this sees a two-week burst and then silence. If you go this route, tie the ask to a fixed moment (the card machine, the mirror check) rather than goodwill — it decays slower, but it still decays.
Cheap and passive — and that's the problem. A poster asks everyone, at no particular moment, with nothing in it for the customer. Most people never scan it. Barbershops that have run QR posters for reviews or tips overwhelmingly report they did nothing. Fine as a supplement; useless as the plan.
The right idea — a direct, personal ask on the customer's phone — with two catches: you need every customer's number collected at the till (friction, and most shops don't), and generic tools send on a timer rather than at a moment that means something to the customer. Better than posters, and worth it if you already collect contact details at booking.
A link in your Instagram bio or on your site removes one step for a customer who was already going to review you. It doesn't create reviews — the customer still does all the work, unprompted. Have one anyway; expect little from it.
The approach that consistently outperforms the rest: ask a specific, happy customer at the moment they're most likely to act — when their visit registers on their phone, or when they walk back in for a second cut (a returning customer is a happy one, by definition). The ask is personal, timed, and tied to something the customer just did, which is why it converts where posters and timers don't.
