How do people wash their hairs in different areas?

Actually I've never washed my hairs since the day I was born.

hi... I wash my hair everyday. People in my country wash theirs at least once a day. I wash my hair with shampoo that has conditioner in it to make my hair smooth and full. Good day... Thanks Laratri

I wash my hair everyday. People in my country wash theirs at least once a day. Whenever I take a shower in the morning, I wash my hair with shampoo that has conditioner in it to make my hair smooth and full. Shampoo that doesn't have conditioner on it make hair dry. at night before going to sleep, I take a shower and just wash my hair (without any shampoo or hair product),though twice a week I massage conditioner on my hair and scalp during my evening shower. I do this so my hair doesn't dry out and die on me due to constant blow-drying. I used to shampoo at night but I though that might cause damage in my hair/scalp so I just rinse it night and occasionally use conditioner. I guess the reason we wash our hair everyday is because of our hot weather. We always want to feel refreshed and our scalps to smell good. The hot weather makes us sweat a lot and the scalp tends to smell bad after a day. These habits die hard, we went to HK one summer (summer in my country) but it was just after winter in HK, it was really cold and we never went anywhere without a jacket, but we still took a bath everyday even if it was freezing cold!

I read in an article that when you wash you hair you should use warm water first to clean it from oil and dirt then wash it with cold water to close the cuticles of the hair. Apply shampoo on the scalp and not at the ends because that will cause damage. After that rinse the shampoo off.
