Hair Topics

i have naturally straight hair, i don't get it treated, i used to use baby shampoo and then conditioner. i don't put harsh chemicals in my hair and don't blow dry, straighten, or curl it often. and someone told me that you should not just use hair iron alone if you want your hair straight because the heat may damage your hair. i think you should use an oil first, but i don't know what it is. i just see her putting it in my hair.
