If you are a person prone to allergies, you may need to take extra care of your scalp. Find out all about it in this article.

Taking care of your hair health may have to go beyond keeping your strands beautiful and shiny. If you are prone to allergies, you may need to be extra careful with any components you put in contact with your scalp. Exposure to substances present in products such as hair dyes can trigger allergic reactions that cause discomfort and itching.


In this article, we are going to explore the care you need to help you have an irritation-free scalp!

Causes of hair allergies

Hair dyes are often identified as one of the main causes of hair allergies, but these can also be triggered by other hair products that may contain some aggressive substance, such as parabens, dyes, sulphates, ammonia, among others present in shampoos or masks. Some of these ingredients can trigger allergic reactions. The symptoms are diverse, from itching, redness and irritation of the scalp (contact dermatitis) to more serious cases such as inflammation of the face.


To try to avoid this, you can take some precautions before using hair dyes, for example. Here are some important tips to consider:


1. Take a sensitivity test

Before applying any hair colour, perform a sensitivity test. Apply a small amount of the product to a sensitive area of the skin, such as the inner part of your arm, and wait between 14 and 48 hours. If you experience allergic symptoms such as redness, itching or any swelling, avoid using this product.


2. Read product labels

When purchasing hair dyes, carefully check the list of ingredients present in the formula. If you have had allergic reactions to any specific component, avoid any products that contain it!


3. Look for alternatives

There are many hair dye options that are formulated with ingredients which are less likely to cause allergies, such as ammonia, for example. Consider these alternatives if you have an allergy history.


4. Consult a professional

It is always recommended to seek advice from a professional before undertaking any hair procedure, as they will assess your condition and recommend the best approach to avoid allergic reactions.


In addition to these precautions, wash your hair regularly with gentle products suitable for your scalp type and avoid the excessive use of aggressive chemical products, such as setting sprays or gels, which can harm your hair and cause allergies.

Taking care of your scalp is essential for a beautiful, healthy-looking hair!
