I have been completely natural since 9/2004 (my big chop). I guess I vote YES - but only for special occasions because I have been 3 times for senegalese twists, twice for weaves, once for my wedding, and once for my college graduation. I usually self style, and I am not good at it. Still, after almost 7 years I do not most like styles when I do them myself. I haven't really had the time to groom it, or learn what looks good on me.
What I can say is that no matter how unsatisfactory my self style is to me, it is more satisfactory than the feeling my hair has after a trip to the salon. Twists and weaves in the salon have pulled out my hair around the edges, and once I lost a silver-dollar sized patch in the crown from a weave that was braided too tight. When my hair is pressed/curled, it gets heat damaged...loses the natural curl pattern and I hate it because it further ruins the look of my natural styles. I definitely don't get trims because I don't care about even right now and won't until I get to my goal length. I only do S&Ds.
Now it's not to say that I am anti-salon because I'm sure there are some good ones, but I haven't been to a salon in a long while (I even did my first weave a few months ago and loved it!) and see no reason in the near future to do so.
