Do you mean no one you know? Im in my 30s. We had conditioners. and I didnt know anyone with curly hair who would shampoo and wouldnt follow up with a conditioner. Grease has always been a problem in my hair and scalp because my hair is fine and grease is so heavy it clogs my pores and gives me dandruff. My mom pressed my hair now and then as a child but must have been a pain because by age six I had chemically treated hair. I used moisturizers like wave noveau or pink lotion. Not grease. As far as heat damage, you might not know someone has it unless they tried to wash and go. Only a few of my relatives did that. . I think excessive heat is why my grandma and great grandma had thin hair that never got much past apl. I tried to use grease natural and had to immediately wash my hair it was so weighed down and greasy. I am glad you found what works for you but we are all individuals.
