With locations in Madrid, Hollywood, and New York, the European-owned Shlomi Salon houses a staff of stylists who are well-acquainted with the ins and outs of glamour. In addition to trimming and styling manes behind posh leather chairs, they perform a host of other cosmetic services that includes hair coloring and hair removal, as well as permanent and temporary makeup application. To straighten and strengthen frizzy or dry locks, they’ll slather them in their own line of keratin products, which includes a pre-shampoo, a treatment product, after-shampoo, and an after-conditioner.
