Stylist Stephanie Rider updates locks with premium products, and has trained her hair-sculpting talents on celebrities such as Mandy Moore. In 90-minute full keratin treatments, the maestro paints locks with formaldehyde-free Global Keratin, a potent potion brimming with proteins and smoothers that aim to soften and strengthen locks for up to three months. The rich treatment is designed to increase both volume and smoothness, much like whispered pickup lines through a megaphone. Polished locks can blow-dry quickly, docilely accept brushing and styling, and can be worn either curly or straight. The 45-minute express treatment smoothes locks for three to six weeks, ousting frizz and boosting shine to hair that’s curly, straight, or filled with bees.
