I had to go with seriously think about it. If I was single, I'd go with yes, but my husband likes waves and curls and he's wonderful about encouraging me to keep the curly look
I've learned to get along with my hair after all these years (and years) and if my hair was thick on top, that alone would have had me saying "no way". I do, however, think my face looks better with straight hair and bangs, which I do straighten even now. For me, becoming friends with my waves/curls has been a very good thing and my hair has become healthier for it. The top of my head is always a daily "what's it gonna do today" thing and that's really the only frustrating thing about my hair.
And I do enjoy my "PJ-ism"
