Same here. The front of my hair is the only part that doesn't knot, coil or curl. Just pure waves. Weird, eh
Oh, and also... if anyone was wondering... now when I examine a hair that may have fallen out, I notice that the part that was henna'd looks very straight, and the new growth is... very curly. However, I don't let this fool me, because it doesn't look straight on my head. I'll try to get a picture of this and show you.
