When I got Penny, she had just grown out her mane after she rubbed it off in one section. I keep her mane braided now because she gets sooo sweaty when it's down. I took it out today to redo it and it was wet from just hosing her down so it was straight and HOLY COW it's grown! I got her last October and the before pic is from then.
Before: (october 2009)
Now: (kinky form braids)
Now: (hosed to make straight)
All braided up again:
Forelock before: (was thinned to make less frizzy I think)
