I am thinking of buying a Mac hair perfume for myself, however, I want to confirm few things before I spend my money on this purchase. I have seen in the advertisements about the hair perfume that they add fragrance to hair. However, I want to confirm if it would be all right to spray it after I use a curling rod on my hair. Do you think it is advisable to wash hair in the evening, or it wonât be harmful for hair to leave it overnight? Please advise appropriately. Thanks.
