Lexi has been a little fluffy, and I have been noticing in the last month or so that she is slowly loosing her fluff.

Her hair is starting to lay really flat. Even though it looks and feels very soft and smooth, it's not as fluffy. I love her fluffy face, what is going on? Her hair isn't getting thin, just straighter.
Here are some pics, it's hard to tell though cuz, I tried blowdrying her to get some fluff back. (it did help a little it just didn't last long)
