Booking on price alone and auditing nothing
The cheapest quote often prices out exactly the invisible steps that matter: autoclaved tools, full cure cycles, a chelating wash before keratin. Compare like-for-like scope across a few vendors and spend one minute inspecting the kit on arrival. The infection or ruined treatment you avoid is worth far more than the difference between quotes.
Treating bridal bookings like a normal appointment
One artist cannot finish a bride and four relatives in a morning, and no trial means the first attempt at your wedding look happens on your wedding day. Confirm team size in writing, hold a photographed trial, and build an hour of buffer before photos.
Booking clinic-grade procedures as home visits
Injectables, laser and aggressive peels are medical procedures that belong with DHA, DoH or MoHAP-licensed practitioners in licensed premises, whatever an Instagram account promises. A home beautician's scope is grooming and cosmetics. If an offer blurs that line, the correct response is to decline and book a clinic.
