When you color your hair, you're actually changing the color of the pigment in your hair shaft. Hair pigment is made up of two types of melanin: eumelanin and pheomelanin. Eumelanin is responsible for brown and black hair, while pheomelanin is responsible for red hair. The amount and type of melanin in your hair determines your natural hair color.

When you use hair color, you're adding artificial pigment to your hair shaft. This pigment can either be temporary, semi-permanent, or permanent.

* Temporary hair color washes out after a few shampoos. It's a good option if you want to try out a new color without making a long-term commitment.

* Semi-permanent hair color lasts for about 6-8 weeks. It's a good option if you want a longer-lasting color than temporary hair color, but you don't want to commit to a permanent color.

* Permanent hair color lasts until your hair grows out. It's the best option if you're looking for a long-lasting color change.

How to Choose the Right Hair Color

When choosing a hair color, there are a few things to keep in mind:

* Your skin tone. Certain hair colors can make your skin look paler or darker. If you have fair skin, you might want to avoid dark colors that can make you look washed out. If you have dark skin, you might want to avoid light colors that can make you look too pale.

* Your eye color. Certain hair colors can bring out the color of your eyes. For example, blue eyes can look stunning with blonde or red hair, while green eyes can look beautiful with brown or hazel hair.

* Your lifestyle. If you're active or you spend a lot of time in the sun, you might want to choose a hair color that is less likely to fade.
