Seems a bit odd, but then...
Shoving chemicals on your head to "clean" and coat it also seems odd.
Most shampoos are formulated to strip everything from your hair. Conditioners are then designed to coat it with silicone-based products that leave your hair feeling smooth, but in reality the hair under it is damaged and dry.
Some people use an oil treatment before cleansing their hair. It's massaged into the scalp only and helps with blood circulation, relaxation, gently loosening up flakes and dirt. The Aveda hair salon I go to actually does a scalp massage with a scented oil before washing and cutting. It's hugely relaxing and feels so luxurious.
I've been doing a lot of research lately into DIY natural hair care and have found out that there are SO many alternatives to the chemical shampoos that I wouldn't be surprised at anything they put out there. Still trying to find my perfect happy hair place, but I will tell you this: I haven't washed my hair in a week and it is still clean and extremely soft...like a kitten. Or baby bun bun. ^_^
