Q: Do I really need to shampoo and condition every day?

It depends on the condition of your hair. Dry, damaged tresses could do without the daily shampoo and should be fine with only conditioner from time to time. On the other end of the spectrum, oily locks can get by with a weekly conditioning. In-between types can be cleaned every other day. Ask your lovely and talented stylist to suggest a cleansing routine.

Q: How can I be one clothing size at one store and another size at a different store?

Clothing sizes were meant to be an industry-wide standard to help consumers find clothes that fit them. But manufacturers and retailers have been known to tweak the numbers. For example, if a designer sees his or her ideal woman as a Marilyn Monroe type, then a size-10 woman with an hourglass figure should have no problem fitting into their size 10. A woman with a less curvy shape might find waistbands tight and blouses ill-fitting. Other labels may size down to make the customer feel better (i.e., throwing a size-8 label on a size-10 skirt). In a nutshell, sizing is a mess. That’s why you should never buy anything without trying it on first. For those who shop by catalog or over the internet, there’s a website called fitme.com that will translate your measurements into the sizes of more than two hundred brands. It’s free to register, so give it a boo.

Q: I’ve become noticeably hairier in my 20s. What gives?

It’s something I like to call second puberty. Like first puberty, it involves hair growing in places where there was no hair before—say, on your back or on the tops of your toes. You may have noticed other changes in your body, too, such as a baby beer belly and the urge to go to bed at 9 p.m. Basically, your body fiddles with your hormones every decade, and that may include hair sprouting out of your ears and on the top of your nose.
