hair color side effects

Nowadays, applying hair dye has gone beyond being a cosmetic procedure to hide grey hair. It is in fact, used to express one’s personality. While coloured hair can make you look younger, researchers have also reported some possible harmful effects of applying hair dye. [1]

Some of the common side effects include skin redness, scaling, itchiness, split ends, dryness, lustreless hair, excessive hair loss, greying and may sometimes cause serious side effects like asthma, dermatitis etc. Perform a patch test at least 48 hours before getting your hair coloured.

Some of the side-effects of using hair dye are:

Common side-effects:Clinical studies report that some of the major side-effects are skin redness, scaling, itchiness, split ends, dryness, lustreless hair, excessive hair loss and greying. [2]

Contact dermatitis: Hair colour has been associated with allergic contact dermatitis, which may lead to hand eczema in hair-dressers and severe eczema of the face in users. It has been found that Para-phenylenediamine (PPD), the key ingredient present in permanent hair dyes, is the cause. [3]

Other side-effects

  • 1. Angioedema (swelling of deep layers of the skin) [4]
  • 2. Ulceration [5]
  • 3. Conjunctivitis
  • 4. Asthma
  • 5. Various forms of cancers such as bladder cancer, leukemias, lymphomas and breast cancers [6]
  • 6. Risk of malignancy in the unborn child [7]
  • 7. Dye-induced depigmentation

Unfortunately, it has been observed that a majority of users lack adequate knowledge regarding such products and their side effects.
Worried? Don’t be! Here are a few ways you could minimize the side-effects of hair dye[8]. After all, precautionary measures never hurt anyone!

  • Cut down on the use of or completely avoid chemical based hair dyes
  • Use natural hair dye products as they usually have minimal side effects
  • Temporary hair dyes are the safest as they fail to penetrate the hair shaft
  • Be sure to conduct a patch test first

Here’s how to conduct a patch test:

Apply a little dye behind your ear or on the inside of your elbow and leave it on for two days. Do not use on your hair if you see any signs of rash.

When you’re colouring your hair, remember to follow some basic guidelines such as:

  • Never leave the colour in for a period longer than advisable
  • Always wear gloves
  • Don't mix two or more different hair dyeing products.
  • Make sure you wash your hair thoroughly in the end

Now you know all you need, so go ahead and paint the town (or dye your hair actually) red!
