Why Does My Scalp Itch after I Color My Hair -Find Out Why

If you notice an itch after you color your hair it could mean two things: You’re either allergic to the hair dye or you have scalp dryness due to the use of peroxide and other chemicals.

Luckily, there are ways to remedy this and also, and there are ways to determine which of the two culprits is actually responsible for your itchy scalp

Why Does My Scalp Itch after I Color My Hair

Allergic Reactions

A lot of hair dyes contain paraphenylenediamine (PPD), a chemical compound known to cause allergic reactions in people with PPD-sensitivity.

PPD causes reactions because it is partially oxidized when mixed with hair dye. People who are sensitive to PPD will experience several allergies. Amongst them is an itchy scalp.

Some people may experience itching along with the other symptoms below

  • Swelling of the eyes, lips, hands, and feet
  • Feeling faint
  • Difficulty breathing
  • Tummy pain and vomiting

If the itch in your scalp is due to an allergic reaction to PPD, it could either persist for days or come along with other symptoms. In some cases, the itching could start 48 hours after you have dyed your hair.

How to Remedy This

Wash off the dye with a mild shampoo and warm water if there is any inflammation, apply a steroid cream along with a moisturizing treatment to calm your scalp.

Take oral antihistamines like Benadryl to help stop the itchiness.

If you do not notice any changes after doing this, then you should consult your doctor. Chances could be that you need a prescription steroid and stronger antihistamines to stop the itching.

Minor Itching

Sometimes, the itch in your scalp could be due to mistakes you made while applying the dye. It is always recommended to get a professional to color your hair, but if you are a die-hard do-it-yourselfer, you might want to consider crossing out hair dyeing from your list of skills.

You may notice a minor itch in your hair after dyeing which could be due to the use of excess hair dye.

If this is the problem, then you’re in luck. All you need to do is simply wash your hair with warm water and an all-natural shampoo.

Avoid using shampoos with harsh chemicals as they could react with the hair dye making matters worse.

Reaction Due to Hydrogen Peroxide

Another reason why your scalp itches after you color your hair could be due to hydrogen peroxide. If you use too much hydrogen peroxide while coloring your hair, your skin will become irritated and itching may occur.

This situation is more likely to occur if you’re coloring your hair yourself.

To remedy this, you should wash your hair with warm water and a mild shampoo.

There are so many precautions and so many techniques to follow when it comes to hair dyeing. It’s best to leave it to a professional and save yourself the stress of looking for treatment and remedies.

How to Avoid an Itchy Scalp After Coloring Your Hair

Get a Professional

Sure you would save a lot of money and learn a skill by doing it yourself, but if you end up with an itching scalp or severe allergic reactions, you may spend a lot more and later regret your decision

Professional hairstylists have seen the good, bad, and ugly with hair dyes so they know just how to get about it.

Some hairstylists keep tabs on their clients while their hair is being colored. They ask them to watch out for any burning or stinging sensation which would develop into an itch later on.

All these tender, loving, care ensures you have an itch-free scalp and you can enjoy your new color as long it stays on your hair.

Do a Patch Test

A Patch test helps to determine if someone is allergic to a certain product.  Before trying out that new hair dye, get a small amount of it and dab it on a non-sensitive. Watch out for reactions like an itch, redness, swelling, or burning sensation.

If you notice any of these, then you’re allergic to the hair dye and would have to opt for alternatives. Unfortunately, there are very few alternatives.

You are less likely to find an effective hair dye without PPD and if you do, you might also end up being allergic to it especially if it contains para toluenediamine (PTD).

So how do you go about it?

First, get your patch test done at an allergy clinic. Allergy clinics don’t just determine if you’re allergic to a product, they determine the exact compound that is triggering your allergies. You can now avoid products with those chemicals when shopping for hair dyes.
