Some ideas!

- Honey
- Egg
- Olive/vegetable/coconut oil
- Coffee (if you've got dark hair)
- Banana
- Avocado
- Plain yogurt

Eggs.. most definitely!  That is, if your hair likes protein 

Mine loves it, so.. 

An idea... buy some "translucent" henna or.. if you wanted to color, regular henna (which, by the way, if you have a Sally's Beauty Supply there, they sell a great selection of henna!) mix it up however you like and once the water/henna mix cools, add a couple of eggs....

Pretty colored (or uncolored) hair that's shiney and happy!

Also... try tea rinses!  Blondies do well with chamomile, while brunettes/dark hair does well with regular black teas, and redheads can look for rose hip or chicory (Try Bigelow Orange and Spice)  Just boil a small pot of water, add the tea bags, and brew until very dark.. allow to cool.. then add to a big container and fill with water...  I mix these tea rinses up when I do a vinegar rinse and.. NO SMELL!  Whoot!
