In what way can your ZIP code be of any use besides filling in shipping info at checkout? Believe it or not, but your ZIP code can actually help you have better haircare treatment. Your ZIP code shows the climate you live in. Prose uses this information to seasonally adjust your haircare formulas to swiftly respond to new weather conditions. But before doing that, Prose will ask you to complete a short quiz. Based on your answers, the company’s chemists will assemble haircare formulas that will work best for your hair. They will regularly correct the formulas throughout the year. Isn’t that impressive? Prose doesn’t merely sell you haircare products. They make sure you always receive what you pay for. By the way, what do you actually pay for, haircare products? No, you don’t. You pay for beautiful and healthy hair. That’s Prose’s mission and chief focus.
