How long does she stay in time out? I read to keep them there one minute per year age, so six minutes for the older daughter.

Can she blowdry her hair herself? No she won't do it very well at first but she can learn. Also you might use a wide tooth comb rather than a brush. I read that you shouldn't brush/comb wet hair because it stretches and breaks it so maybe wash it the night before and comb in morning? Have you tried Johnson's No More Tangles Detangling Spray? My mom used to use that on my sister's hair.
