Hair grows from a follicle under the skin. The colour of the hair is determined by pigment cells at the base of the follicle and depends on genetics and hormones. As we grow older, these pigment cells start to die and our hair turns gray.

In the body, hair grows from a follicle under the skin. The colour of your hair is determined by pigment cells at the base of that follicle. These pigment cells are either present or absent depending on genetics and hormones. As we grow older, these pigment cells start to die and our hair turns gray.

Hair colour can range from black to blonde to red or any shade in between, depending on how many pigment cells there are in each individual strand.

Permanent hair color will only penetrate into freshly grown hair. As we age, the positioning of the melanocytes can cause our hair to turn grey, white or silver. Permanent hair color will not be able to penetrate into these hairs, as they are no longer alive and contain no active melanin.

Chemical dyes treat the hair shaft with hydrogen peroxide and ammonia to break down your natural melanin and take out your natural tone. The dye molecules then enter your hair, saturating it with long-lasting color.

Hydrogen peroxide is used to break down the melanin, which is what gives people their natural hair color. Ammonia opens up the cuticle of your hair (it’s like a window into your strand), allowing for better penetration by the dye molecules that bond to it, making them last longer than they would regularly on its own.
