People notice your manicure. It's a fact of life I try to remember at all times because if I'm not careful I'll end up with fingernails at 5 different lengths and a hangnail or two. Find out how to give yourself a manicure, the most flattering nail shapes, how to make your manicure last longer, how to make nails dry faster and much more.

About's fashion guide Cynthia Nellis wrote a very fun piece that I couldn't agree with more: "5 Things a Grown Woman Should Never, Ever Wear" starting with No. 1: Overalls belong on a farm, not on you.

I couldn't agree more, although I have to say when I renovated my first house, I thought I rocked the overalls. It was fun to watch them go from blue to white (paint, plaster and floor dust) in a matter of months. And I've been told a do-it-herselfer woman is pretty darn sexy. That said, I didn't go anywhere in the overalls, except once or twice to Home Depot.

Few of us have perfect eyebrows. A famous makeup artist once said he had never seen a model who didn't need to fill in her brows. But how to do it perfectly? Do you use a pencil? Should you splurge on special brow powders? And what's the best way to mask graying brows?

The best brow tips I've read come from makeup artist Bobbi Brown.

The trick, according to Brown, is to use a dark eyeshadow (dark brown will suit most women) and a slanted eyeliner brush. Simply dab the brush into the shadow and the sweep onto brows in upward strokes. This will fill in the sparse spots and cover over gray hair.

How to keep the shadow in place all day? You might try "setting it" with hairspray. Spray onto finger and "dab" onto the newly colored brow. For a more elaborate version of Bobbi Brown's eyebrow tips, check out, "How to Fill in Sparse Brows."

Today I got an email from a 25-year-old with combination skin who is new to skincare and tried Purpose Cleanser (on my best cleanser list). She also tried Ponds at the same time (also a "best" cleanser). She's allergic to one of them or the combination of them because shortly after trying these products, her skin became red and itchy and stings when she tries to calm her skin down with moisturizer.

My advice to this reader is to stop using both products. While sometimes your skin needs a few days to become acclimated to a new skincare routine and a bit of redness is OK, itchiness and peeling is not OK. Both Purpose and Ponds are wonderful products and the choice of millions of people worldwide. But unfortunately, this reader is likely allergic to an ingredient in one of the products or reacted to a combination of both of them.

I advised her to consider a sensitive skin product, like Olay's Foaming Face Wash for Sensitive Skin. I also told her the big secret to great skin is sunscreen. She should use it every day rain or shine. She'll thank me in 10 years when people tell her she looks 25, not 35.
