Every product in a mobile kit has a temperature history, and in a UAE summer that history matters. A van parked in the sun reaches oven temperatures within an hour; nail polish separates and thickens, gel can begin to polymerise in the bottle, wax loses its formulation consistency, and creams split. The visible symptoms during your appointment are gel that drags and bubbles, polish that will not level, and wax that has to be overheated to flow, which is how burns happen. Professionals who take the trade seriously run insulated cases or simply never leave product in the vehicle. It is a fair and revealing question to ask a vendor how they store their kit in summer.
Humidity is the other half of the chain, and it peaks on the coast in July through September. Blow-dries collapse faster in 80 per cent humidity, so an honest stylist will steer summer event clients toward styles that fail gracefully, waves rather than poker-straight, updos rather than loose blowouts, and will finish with anti-humidity sealing rather than more heat. For makeup, the killer is the transition: you leave a flat chilled to 21 degrees, cross a car park at 44, and condensation forms on your skin exactly like it does on a cold glass. Long-wear silicone-based primers and proper setting exist to survive that specific ten minutes, which is why event artists here use them by default.
