Update: hair was ok-ish today, and important day went great.
My hair does feel really dry again...
Would I maybe be high porosity since I seem to be losing a lot of moisture? (This morning it wasn't dry, not really moisturised a lot either, but definitely not dry... now it really feels dry again).

I will try the banana smoothie next thursday and see how it goes. If my hair is dry afterwards (so if I seem to be responding badly to the proteins) I will do a deep conditionerthingie afterwards.
Does that seem like a good idea?

Oh... and I'm getting jojobaoil tomorrow I guess...
What do you think about that?
