idk think so. Because the harmful pollution sitting on your scalp and pores along with the Dirty oil that causes bacteria would be on there longer. If you lived out in the country that might be different. There are Natural good oils in your hair and to preserve those use a natural Jojoba oil shampoo. It will clean and wash away all of that but leave those important oils in your hair that normally are stripped with conventional products.
