The Importance of Patch Skin Tests

Whether it’s a bold new colour or just covering up those pesky greys, it's always exciting to switch up your look. However, before you take the plunge, there's an important step you shouldn't overlook: the patch skin test.

What is a Patch Skin Test?

A patch test, also known as a skin sensitivity test, is a simple procedure that involves applying a small amount of the hair dye formula to your skin to check for allergic reactions. This is crucial because hair dye contains chemicals that can cause irritation or allergic reactions in some people. Even if you've used hair dye before without any issues, your body's sensitivity can change over time, so it's essential to do a patch test every time you dye your hair.

Why is it Important?

1. Identify Allergies:

Hair dyes contain a variety of chemicals, such as ammonia, hydrogen peroxide, and paraphenylenediamine (PPD), which can cause allergic reactions in some individuals. These reactions can range from mild irritation to severe swelling and even anaphylaxis in extreme cases. A patch test helps identify whether you're allergic to any of the ingredients in the dye before applying it to your entire head.

2. Avoid Skin Irritation:

Even if you're not allergic to the dye, it can still cause irritation or sensitivity on your scalp or skin. A patch test can help determine whether the dye will cause any discomfort or irritation before you commit to colouring your entire head of hair.

3. Ensure Desired Results:

Sometimes, after a skin patch test, we can complete a hair strand test. By conducting a strand test, you can check if the hair dye will give you the desired colour result. Sometimes, the colour may turn out differently than expected due to factors like your hair's natural colour or previous treatments.

How to Perform a Patch Test:

1. Choose a Testing Area:

We select a small, discreet area on your skin behind your ear or on the inside of your elbow.

2. Prepare the Dye:

Mix a small amount of the hair dye according to the instructions provided by the manufacturer.

3. Apply the Dye:

Using a cotton swab, apply a small amount of the dye to the chosen test area.

4. Wait and Observe:

Leave the dye on for the recommended time (usually 24-48 hours), and during this time, avoid washing the area.

5. Check for Reactions:

After the allotted time, check the test area for any signs of redness, itching, swelling, or irritation. If you experience any of these symptoms, you should contact us (or your hair stylist) do not proceed with dyeing your hair.

In Conclusion

While getting your hair dyed can be a fun experience, it's essential to prioritise your safety and well-being. A simple patch test can help you avoid potential allergic reactions, skin irritation, and ensure that you achieve the desired results. Don't skip this crucial step!
