How Does Dye Affect Your Hair?
Hair dyes consist of a cocktail of chemicals – developer or oxidizing agent, ammonia, and coloring agent.
Ammonia opens the hair cuticles, and hydrogen peroxide, a commonly used oxidizing agent, penetrates the hair shaft to strip its natural pigment. When your natural hair color is gone, the coloring agents get to work and dye your hair (1).
Thus, hair dyes can alter your hair color permanently. But, does dyeing your hair damage it in any way? Check out the next section for your answer.
Key Takeaways
- Hair dyes may damage your hair as the chemicals in them open up hair cuticles and strip away the natural pigment from your tresses.
- The damage caused by a semi-permanent hair dye is minimal compared to permanent hair dye.
- The damage caused by dyeing can be managed using heat protectants and color-safe and hydrating hair products.
Does Dyeing Your Hair Damage It?
Yes, hair coloring leaves your locks prone to damage. A dye does not merely stain your hair but penetrates the shaft to alter the natural hair pigment. Thus, frequent hair dyeing can strip the protective lipid layeri The layer of fatty acids over the hair shaft that protects it from external damage and aids in keeping hair healthy, strong, and shiny. from your hair, called the cuticle, leading to roughness and damage.
Moreover, a hair dye’s damage extends beyond your tresses. The side effects of hair dyeing may also affect your scalp leading to allergies, dryness, scalp itchiness, and redness.
A study published by the American Chemical Society in 2022 revealed that endocrine-disrupting chemicals (EDCs), like parabens, bisphenols, and phthalates found in hair dyes, can interfere with hormone signaling and affect the development of breast tissue. Exposure to hair dyes with EDCs, especially during childhood and adolescence, may lower the age at menarche and increase breast cancer risk. About 33% of women over 18 and more than 10% of men over 40 in Europe and the United States dye their hair. A population-based study from the United States involving 363 non-Asian women demonstrated an increased risk of bladder cancer who exclusively used permanent hair dyes. The risk involved was higher with longer duration and increased frequency of use.
Rachwat, a beauty blogger, shared how frequently dyeing her hair damaged her tresses: “Although my hair went red, this time a deeper one due to the purple base, I had really damaged my hair. One patch on the top of my layers on the right hand side of my head had actually gone white, elasticated and snapped off (i).”
What can cause more damage to your locks – dying them a lighter color or a darker one? Scroll down for more information.
Light Vs. Dark Hair Colors: Which Is More Damaging?
Both light and dark hair colors use hydrogen peroxide that oxidizes your natural hair color, increasing the risk of hair damage. The developer (hydrogen peroxide) opens the cuticle and removes as much of the natural pigments from your hair as necessary to dye it permanently. Although it should be targeting melanin, the developer also interacts with keratin molecules, making your hair weak and prone to damage.
When depositing color, you are putting color into the hair strand, where the artificial color molecules will cling to the original color molecules. When lightening the hair, the hydrogen peroxide lifts the cuticle and pulls the original color pigment out of the hair instead of depositing color to cling to it. Once these pigments have been removed from a hair strand, you cannot get them back.
Hence, choose a shade close to your original hair color while dyeing it permanently. This can be less damaging than darkening or lightening your hair beyond the range of its natural shades.
Is a semi-permanent hair dye just as damaging for your hair? Find out below.
Does Semi-permanent Color Damage Your Hair?
No, a semi-permanent hair color is not as damaging as a permanent hair dye since it merely coats the hair cuticle. It is free of peroxide and ammonia and does not bleach the natural pigments of your hair.
However, semi-permanent hair dye has its cons. You will only be able to darken the hair color and not lighten it with semi-permanent hair dyes. The color will fade after a few shampoo washes and requires frequent reapplication.
TriviaDyeing your hair changes its structure, especially if you are using permanent hair color. But can the condition of your hair determine the severity of hair dye damage? Let us find out in the next section.
Hair Dye Damage: How Your Hair’s Condition Makes A Difference
Your hair changes the way it feels and behaves after dyeing. But the state of your hair at the time of your dye job also makes a difference.

You cannot just apply hair color anytime. Your hair should be clean and free of any buildup for the color to stick to your hair. Hence, wash your hair 24-48 hours before dyeing it for effective results.
