When it comes to buying hair bleach at Sally's, the answer depends on the laws and regulations in your particular area. In some areas, a license may be required in order to purchase certain types of hair bleaching products. Generally speaking, if you are attempting to buy a product that is intended for professional use only, then you will likely need a license in order to make such a purchase. However, if you are just looking for an everyday over-the-counter type of bleach that can be used at home without any special training or certification required, then chances are good that no license will be needed when purchasing from Sally's. It is always best to check with your local beauty supply store before making purchases like these so as not to run afoul of any applicable laws or regulations.
