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 (2).
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.
Does Dyeing Your Hair Damage It?
Yes, hair coloring makes 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 XThe 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 chemicals present in hair dyes can cause 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.
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 dye is not as damaging as a permanent hair dye since it merely coats the hair with colors. 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.
Weak and fragile hair (means you have damaged cuticles) might not be able to hold the color. Also, coloring your weak hair can lead to breakage, hair fall, frizz, and broken cuticles. Ideally, you should stop dyeing your hair if it is already fragile to prevent any further damage.
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.
If you want to color your hair, first, test its condition – how healthy or damaged it is. Understand the impact hair color will have on your hair and choose your options wisely.
