Learn more about what to do if you develop an itchy scalp after hair dye.

Hair colouring can be a fun experience, almost like a new accessory to your personality. But if that same hair colour leads to an itchy scalp, you could be left scratching your head in bewilderment.

Why do you get an itchy head after hair dye?

Hair dyes contain a large number of chemicals that are essential to the process of colouring your hair strands, such as PPD, ammonia, and hydrogen peroxide. But these chemicals could also be the reason for your hair dye itchy scalp. Some of these chemicals can even be toxic, depending on the type of hair dye you use. Let’s explore some of the common reasons for an itchy scalp after hair colour:

• Allergic reactions – The most common causeof an itchy scalp is your body reacting to this cocktail of chemicals.
• PPD – A known allergen, PPD can lead to irritation on your scalp and cause itching.
• Toxic chemicals – Lead acetate is a harmful chemical found in certain hair dyes which can lead to inflammation and itching.
• Exposure to scalp – People often end up applying hair dye directly to the scalp, which can cause chemical burns and irritation.
• Drying out natural oils – The chemicals can disrupt the natural lipid layer on the skin and lead to a dry scalp. You become susceptible to attack from microbes and germs. This can also cause a spike in oil levels to compensate, which can worsen problems like dandruff.

How should you treat an itchy scalp after hair dye?

Luckily for you, the itchy scalp is usually a temporary effect of the hair dyeing process. You can find various solutions to help you with this:

• Identify the problem – If you have an itchy scalp, you should first understand the cause of it. That will help you identify the appropriate itchy scalp remedy.
• Shampoo – Use shampoos for itchy scalp that can calm down the itch. You can also use shampoos which are meant for colour or chemically treated hair.
• Hydration– A dry scalp is a common occurrence with hair dye. Use oils and serums that can soothe the itch and moisturise the scalp.
• Conditioners – You can use conditioners along with your shampoos, to bring back the moisture to your hair. You can also use products like the Head and Shoulders 2 in 1 Smooth and Silky, which give you the benefits of a shampoo and conditioner in one product.
• Hair Masks – Create your own hair masks at home with ingredients found in your house, like eggs, honey, olive oil or even avocadosAloe vera is a common ingredient that helps soothe the itching but be careful with quantities.
• Heat treatment – Avoid using blow-dryers, curlers, or straighteners. Heat based styling can further dry out your scalp and worsen any inflammation.
• Reduce number of products– Don’t use too many styling gels and hair products. Your scalp is in a weakened situation and you don’t want to create further negative reactions.

It’s important to conduct a patch test for 48 hours before you use hair dye. It affects everyone in different ways and you must be sure before using it on your hair. If the problem persists, it’s important to visit a dermatologist.
