Hair Product Thoughts

Concentrated olive oil (anti-breakage) is probably one of the best hair products I've purchased in a long time. I think getting the concentrated coconut oil (moisture & dandruff) into my hair routine next will help. I'm also considering Soy oil (softness and moisture) and a castor oil treatment (growth), but I don't want to overload my hair and turn it into an oily mess. I could skip the coconut oil and go straight to soy since they both moisturize and I don't have a dandruff problem that Head and Shoulders shampoo can't take care of...so much thought going into purchasing hair products.
