Yep, just a good bath with a moisturizing shampoo will get rid of those flakes... I prefer not to use human products on my animals, but if it works for someone, awesome...you use what you can get! I love mane and tail, and that has never failed to get rid of flakies on my mare. After a bath, I will spray diluted conditioner (mane and tail, again) all over her, which makes her really shine, and helps keep her skin 'moist' after a bath. I almost like the results of the dilute conditioner over things like Peppy, or Laser sheen! She's so soft after, but isn't greasy at all!
