I wore braids once for a year because I stupidly decided to get highlights on my fragile relaxed hair. Braids really do help you retain your length so that you can see the growth that you have, provided they are properly taken care of, moisturized, etc. I practically lived in Khamit Kinks in Manhattan during this period. They are very experienced braiders and were very careful not to pull too tight around the hairline, where the hair is very delicate. I did not want traction alopecia! Don't be afraid to speak up and tell the braider not to make it too tight. I have had micros and I do not like these because they can pull hair from the hair line. They use very few strands to make one braid, so you can imagine how delicate each braid is. Personally, I would go with a thicker braid, just to be safe. Although micros are gorgeous...I prefer cornrows or two-strand twists (though this style is harder to maintain because the hair can come undone).
