It will become weaker and more prone to breakage. Over time with repeated coloring sessions, the structure of your hair changes. Tips to Help You Repair the Damage from Coloring Your Hair So now that you know all about the hair coloring process, what can you do to repair the damage it causes? The peroxide uses an alkaline solution, which opens the hair shaft to allow the peroxide to react with the melanin. Hydrogen peroxide is one of the most common lightening agents. So some gold or red residual color may remain in your hair after lightening. Also, bleach reacts more with the dark eumelanin pigment than with the phaeomelanin pigments within the hair. The yellow color is caused by the natural color of keratin, a structural protein in hair. However, bleached hair tends to have a pale yellow tint. The melanin is still present, but the oxidized molecules are colorless. The bleaching process oxidizes the color molecules. The peroxide used for the bleaching process is extremely drying to hair and is the reason why colored hair can take on a straw-like texture. The bleach reacts with the melanin in the hair, removing the color through an irrevocable chemical reaction. This means the hair shaft isn’t opened up during processing and the hair’s natural color remains once the dye washes out.īleach is used to lighten your hair. Temporary or semi-permanent products don’t contain ammonia. Shampooing removes temporary hair color as you wash your hair or expose it to water. In some cases, several colorant molecules enter the hair to form a larger complex inside the hair shaft. Also, small pigment molecules slip inside the hair shaft, using a small amount of peroxide or none at all. Temporary or semi-permanent hair colors deposit acidic dyes onto the outside of the hair shaft. Conditioners are used to close the cuticle after dyeing to seal in and protect the new color. There are also various types of alcohols and conditioners may also be present in hair coloring products. This is what causes the characteristic odor of hair coloring products.Īfter the melanin (color in your hair) is removed, the new permanent color is added to the hair cortex. Then peroxide breaks chemical bonds in the hair, releasing sulfur. The developer removes pre-existing colors. Peroxide is used as the developer or oxidizing agent. Ammonia also acts as a catalyst when the permanent hair color comes together with the peroxide. This allows the hair color to penetrate the cortex of the hair. This is the same process used when lightening the hair except a new colorant does not have to be bonded to the hair shaft after bleaching.Īmmonia is the alkaline chemical that opens the cuticle. First removing the original color of the hair and then depositing a new color. Most permanent hair coloring products use a two-step process. With the cuticle open, the dye reacts with the inner portion of the hair (the cortex) to deposit or remove the color. If you are using a permanent hair dye, the outer layer of the hair shaft (the cuticle) must be opened before permanent color can be deposited into the hair. To really understand the hair coloring process and what causes the damage, we must take a look at each type of hair color and how they work exactly. In other words, progressive coloring for many years may cause serious damage to your hair if you do not take action to address the damage it has incurred from years of heat, coloring, UV rays, etc. The big damage from hair color is cumulative (as in the number of hair colors/processes performed and the age of the hair, heat styling, etc). Like many things in life, the real damage comes over time when you dye your hair repeatedly. However, your hair may need to be trimmed or cut a bit sooner.
However, the hair that grows from your scalp will grow out normally so only the hair that has been dyed is affected.īut remember the benefits of this damage are that you have a beautiful new hair color and your hair may also be a little fuller and voluminous.
When you dye your hair it lifts the cuticle, altering the hair in a way that will never completely revert back to it’s natural virgin state. Unfortunately, hair Color damages your hair.
But does hair color cause damage to your hair or to your overall health? And we all deserve to have that self-confidence. It can truly transform your attitude and make you feel really great about yourself.
