If you have ever stepped foot in a beauty supply store to buy products to color your tresses at home you may have been surprised by how many different hair coloring terms you can find on the back of a bottle or box. Ladies, class is back in session and today we shall define demi-permanent hair color. Demi-permanent hair color is a coloring treatment that uses no ammonia and activates tints by using a low volume developer. This process is considered “permanent” so you will not be able to simply rinse or shampoo it out with a couple washes. Therefore, if you’re not so sure if you’re wanting a big change or commitment it is probably best to steer clear of a demi-permanent shade.
