A good place to start would be the Island Natural products. It's a good idea to choose a shampoo based on scalp condition and a conditioner based on ends condition. The camomile is another shampoo listed for normal hair on Aubrey's website: http://www.aubrey-organics.com
You might also want to get a bottle of the GPB, which is very popular.
Another consideration is the hardness of your water. If your water is particularly hard, you might experience some difficulties with soap residue. This is where vinegar rinses come in to play. Aubrey also has a rosemary rinse that you can use.
Have fun trying the new products!
