A mask i've done a few times now:
1 tsp honey
1 tsp olive oil (my hair is kinda short, doesn't need that much)
1 tbsp coffee (i'm brunette )
Avocado (as needed to make a paste)

I tried the same with banana instead of avocado, but the consistency of avocado is much better. Easier to mix and to wash out. Leaves hair really soft and hydrated.
