Are you a slave to product? Gel in your hair, polish on your nails, lotion on your skin--these are not luxuries, they're necessities. And they ain't cheap. Not at your level of use, anyway. If this sounds like you, BeautyFirst should be on your list. Aside from offering a hair salon and a wide array of product lines, BeautyFirst also has Gold Card Tuesdays. For card holders, the first Tuesday of every month is the day to stock up on all those potions that keep you looking like your usual fabulous self while saving 20 percent off your purchases, and you know what that means. It means you can buy 20 percent more stuff! The friendly sales clerks will help you find what you need, and they'll explain new items and make suggestions, too. And we like that a lot, because even the most expert product user needs a little guidance sometimes.
