Types of Hair Color

Hair coloring is a common practice in the Cosmetology trade used to enhance appearance and create fashionable hairstyles. Hair color products are generally divided into two main categories based on their ingredients and method of action: Chemical Hair Colors and Vegetable Hair Colors. Understanding these types helps cosmetologists choose the most suitable coloring method according to the client's needs, hair condition, and desired results.

Chemical hair colors are products that use chemical substances to change the natural color of hair. These products penetrate the hair shaft and alter the natural pigment inside the hair. Chemical hair colors are widely used in modern salons because they provide long-lasting and dramatic color changes.
