I don't brush/comb except with fingers or when getting a cut.

I love the Aveda Be Curly product but its horribly expensive.... so I've had to look for other products.
I use an organic hair oil... after my hair is washed with shampoo and then on other days I use a thickened cream like Muk when my hair is mostly dry.

The trick I have is to not touch it. Leave it alone That way the hair doesn't separate. If you are out and find its going frizzy, you can always put some sorbolene lotion or some conditioner straight onto it to smooth it down. I carry a small thing of leave in conditioner for humid days.
