Side Effects of Hair Color

Hair dye is not only for concealing gray hairs. People have started choosing colors for their hair expressing personality and are keen on experimenting with their looks to achieve a vibrant and healthy hair. This has resulted in the hair dyes popularity to escalate, but many are concerned about the side effects of these chemical contents. Hair allergies due to colors are common and it may damage hair.  However, there are natural alternatives such as henna to ensure better hair health.

The trend of hair coloring is not new. The hair color trend is from 1500 BC as ancient civilizations used leeches and natural pigments to color their hair. Now, it is time to consider if hair color or dye is safe.


Hair Dyes Types

Hair dyes can be classified broadly as temporary, permanent and semi-permanent, depending on the peroxide contained in the formula.

Temporary hair dye works for people considering an experiment with a different hair color. This lasts until you wash your hair next time and it sits outside the cuticle and not on your hair surface.

Permanent hair dye has highest peroxide concentration and it delivers deep color into your hair. This will also fade over time, but it will last not less than 8 to 10 weeks.

Semi-permanent hair dye brings color without opening the hair shaft. This deposits color into the cuticles and adds shine. They are gentler alternatives with peroxide in low amounts but may last only for 6 weeks at the most.

Regardless of the hair dye type you choose, it has chemicals and it may pose health hazards. Here is an overview of the side effects of hair color:

Reactions to allergy due to hair dye are common as it has paraphenylenediamine that is a common allergen.  Considering precaution, perform patch test and then apply it to your hair.

Hair dye side effects on the scalp-

Many hair colors can cause skin reaction like redness, burning sensation, itchiness, flaky skin and so on. I advise you to take a patch test before coloring your hair.  After 48 hours if you see any allergic reaction on your skin then don’t apply it to your hair and if you see itchiness and swelling then contact your dermatologist as soon as possible.


The hair dyes have lead acetate and this affects fertility in both genders. The FDA considers the lead acetate level to be not much to get absorbed, yet it can be considered as a cautionary note.

Hair Health

Hair dyes used regularly, particularly permanent color can make your hair brittle. Frequent coloring makes the hair shaft and the cuticle damaged and your hair loses its luster.  If you visit your salon regularly every few months, it may result in dry, rough and damaged hair.

  • Follow safety precautions mentioned on the hair dye packaging.
  • Perform patch test first time.
  • Keep it away from your eyes while applying and wear gloves.
  • Keep the color solution only for the specified time mentioned on the packaging.
  • Do not apply it to your eyebrows or eyelashes.
