Sometimes it's OK to splurge on beauty products -- I finally took the leap and purchased a pocket-sized Mason Pearson brush and a bottle of Rodin's Olio Lusso recently, and I harbor no regrets.

But that doesn't mean I can afford to keep that up all the time or that I'm not making concessions elsewhere in my beauty bag. As you're weighing your hair, makeup and skin options, here's a handy guide to help you make some economical decisions. Of course, these products may not be 100 percent comparable in quality of formula, scent or consistency, but they're close enough for me (even when I'm not constrained by my budget).
