My hair has got needs!

My hair's curly and dyed, re-dyed and dyed some more. I say hair, you say brittle. Add some hairspray and you'd have cottoncandy.That's how bad it is.
While I love my conditioner, American cream from Lush, it doesn't do what it has to do during the winter. It just doesn't. My hair looks lik a bird's nest.

So I am looking for good hair treatments, hot-oils, masques, etc and the more natural, the better. No silicones and such. I save the scary chemicals for the nails and my nails only. That's one obsession where it's hard to go natural, but the hair? Shouldn't be that hard. An important issue is that what I use for my hair, my 4-year old daughter wants to use, so I want it a bit safer than your regular haircare.

I tried the Macadamian hair oil and while did something (not much), it was not very natural (despite it's description) and it was rather expensive. If I am going to pay that much to have nice hair, I want to buy a product that won't take a crap on the environment. I want something my kid can use herself without me thinking the WHO will be knocking on the door, telling me I am doing harm to my kid.

So any and all advice - what do you use? What have you been hearing good things about?
