Combo of marketing consulting and organizational psychology. I have a strong psych background + 10 years experience as a marketing exec, and I use that to (a) help teams work better together (b) help individuals work more effectively within their companies and (c) increase effectiveness of marketing efforts based on psychological principles.
In a word, marketing. 
That's really awesome, Bella. I have a natural bent for understanding the psychology especially behind marketing and presentation, so I've worked with a few companies in the Raleigh/Triangle area to help them improve their image and customer focus. I never went to school for it though, so I just enjoy it kind of as a hobby on the side and a few folks know me for it. I'm really into Quality Control. I mean, I always always always have ideas about how a product/service/etc can be improved. It's just the way I'm wired. Works well in that context.
As to the "sly businesswoman" thing, if you feel comfortable then go for it. If you find it does negatively impact your business, then I guess you can always reconsider, right?
I have a friend's wedding coming up, and because this friend is quite conservative and her family much more so, I feel like going chrome-dome to her wedding would be distracting to her family/guests. I tried to find a nice hat that was "me" yet also matched my dress. Nothing. So I finally splurged on two cheap wigs which I think will look nice. They are basically very similar to my hair before I went sly (except one is a blonde color and I've never had blonde hair). They haven't come in the mail yet but hopefully will arrive in the next week.
I bought this one in color F4_30:

I also bought this one in solid (one-tone) HAZEL color:
http://www.hairwigharlem.com/sensationnel-100-human-hair-bump-collection-wig-urban-pixie.htmlThere are a few times when I just find it more appropriate for me to wear a wig or something. It SHOULD NOT matter if I went naked-sly on my head, but it does. So I try to respect others when respect is due (weddings, funerals, certain parties...). Otherwise, eat my dust. LOL.
