Salon bookings happen at the worst possible moment for a phone call: late at night, on a lunch break, in a queue. A page that only offers a phone number loses every one of those.
Booking has to work at 11pm
Online booking is not a luxury feature, it is the whole point. Even a form that reaches your phone as a message beats forcing a call you will not answer until morning.
Show prices by service and by length
Hair pricing depends on length and condition and everyone knows it. Publish ranges and say what changes them. Hiding prices does not protect the sale, it sends the client to the salon that published theirs.
Your portfolio is your product
Real photos of real clients, grouped by what they asked for: balayage, colour correction, curly cuts. People do not browse your gallery, they look for themselves in it.
Say who does what
Clients book a person, not a business. A short profile per stylist with their specialty and their own work turns a price-shopper into someone asking for a specific chair.
