There are different types of products that get color in your hair. Some colors are put on and then you sit under a dryer for the product to do its color work. This type of color will not last as long as the kind that is applied after the hair has been stripped of most or all of its color which is a process that takes longer. The faster process of almost instant color will only attach itself to the follicle it will not actually enter it. This color may only last for a few washings.
