This Is What Really Happens When You Dye Your Hair Too Often

There are mainly three kinds of hair dye available on the market: temporary, semi-permanent, and permanent. The differences have to do with how much they penetrate the hair shaft and how long they last (via Times of India). All hair dyes are chemicals that change the nature and structure of your hair. Doing so means you have to deal with either short-term or long-term damage. 

According to Healthline, applying any kind of permanent dye or bleach creates a chemical reaction that causes the protein in your hair to lift so the chemicals can penetrate the hair strand. Unfortunately, when you alter the hair's protein structure to get the gorgeous color you want, it can also result in loss of hair strength, reduced thickness, and increased roughness of the follicles. Stylecraze agrees that coloring your hair too much can make your hair prone to more damage because the color goes deep in the hair shaft to alter the pigment. The result can strip the protective layer from your hair and make your hair look dry. The chemicals in hair dye can also cause allergies and redness or itchiness on the scalp.

It is best to keep coloring your hair to a minimum. However, if you are addicted to the process, Mother Earth Living recommends avoiding chemicals like P-Phenylenediamine (PPD), hydrogen peroxide, ammonia, and lead acetate.
