Does it damage the hair in anyway? {for African American hair}
Can you use conditioner in place of oil sheen or petroleum jelly, and other oils?

yeah, if you want oily nasty hair. (no, don't go there)

I would say yes but put the leave in conditioner in your? hair. Try syling products like Beyond the Zone leave in conditioner. It works great. I am pretty sure THIS one might do good. There are others to. But if you use regular wash out conditioner it will make your? hair look nasty.

Davey looks white to me. Conditioner will weigh the hair down and make it appear greasy.
No.

I believe that unless it says that is it a leave-in conditioner then you should wash it out. The conditioner is to condition by adding what the shampoo took out. You can leave it in longer. I would suggest finding a leave-in conditioner.

No. Please don't try that with the normal "rinse-after-applying". According to a magazine I read some time ago, it can cause buildup which could possibly lead to dandruff, itching, or oiliness. It might also make your hair seem limp and heavy because the conditioner might end up weighing your hair down.

However, there are some leave-on conditioners which can give hair look shinier, minus the heavy feel of the first kind (of conditioner). Of course, the formulation of the leave-on type is different from the traditional "rinse-after-applying" type.

well it may get dirtier way faster and make your hair look greesy. my mom doess hair and thats what she had told me.

generally for hygenic sake, we suppose to wash our hair b4 applying hair conditioner.
secondly, whereby you fail to wash your hair, u are simply attracting dandruff into ur hair.
finally, a well washed conditioned hair look more attractive, neat and simple both for African and American hair.

I used to use hair conditioner to wash my hair all the time because it is so thick and conditioner would straighten it out.
I would think conditioner is alright to use but your hair will get dirty quicker without using a shampoo to wash it and just using conditioner...I have done it many times but not anymore.
