What Causes Hair Dye Allergies?

Hair dye allergies occur when your body reacts negatively to certain chemicals found in the dye.

In most cases, temporary or semi-permanent hair dyes are more likely to cause an allergic reaction than permanent dyes because they contain more chemical ingredients.

The most common culprits for causing allergic reactions includes para-phenylenediamine (PPD) in black henna tattoos and paraphenylenediamine sulfate (PPDS) in semi-permanent dyes.

How do I Identify an Allergy?

Itching and Burning

Itching and burning in the scalp or skin surrounding areas where the dye was applied is one of the most common signs of an allergic reaction to hair dye.

The itching can range from mild to severe, but if left untreated, can lead to further complications such as infection or scarring.

Rash

A rash that appears after applying hair dye is another sign of an allergic reaction. The rash may be accompanied by redness, swelling, and/or blistering in the affected area. This type of reaction is known as “allergic contact dermatitis” and should be taken seriously due to its potential to cause more serious health issues if not treated promptly.

Rashes can also appear several hours or days after application, so it is important to be aware of any changes in your skin following the use of a new product or brand.

Swelling

Swelling around the eyes, face, lips, tongue or throat is a symptom of a severe allergic reaction that requires immediate medical attention.

The swelling may occur suddenly following exposure to hair dye and can quickly spread throughout your body if not treated right away.

If you experience this type of reaction you should seek medical care immediately as it can be life-threatening if not treated properly.

Nausea

Nausea is another symptom associated with an allergic reaction to hair dye and can range from mild to severe depending on how sensitive your body is to the ingredients used in the product you used for colouring your hair.

If you experience nausea after using a new product, it is important to stop using it immediately and consult with your doctor about other options for colouring your hair safely without experiencing adverse reactions like nausea or vomiting due to an allergy or sensitivity issue.

Shortness Of Breath

Shortness of breath can occur during or shortly after the application of hair dye due to an extreme allergic reaction known as anaphylaxis which requires prompt medical attention as it can be life-threatening if not treated quickly enough with epinephrine (adrenaline).

If you experience difficulty breathing after using a new product, make sure that you seek emergency medical help right away so that they can administer epinephrine which will reverse the effects of anaphylaxis quickly enough before any lasting damage occurs due to lack of oxygen reaching vital organs like your brain and heart during this type of extreme allergic reaction event.

Tips for Preventing Allergic Reactions to Hair Dye

For many of us, hair dye is an essential part of our beauty routine. However, if you have an allergy to hair dye, the experience can be anything but enjoyable. You can use the Welzo allergy test to identify your allergens.

Fortunately, there are a few simple steps you can take to prevent allergic reactions to hair dye. Here are five tips for preventing allergic reactions when using hair dye.

Patch Test

A patch test is a great way to determine if you have an allergy to the ingredients in your chosen hair dye.

Prior to applying the dye all over your head, perform a patch test first by applying a small amount of the product behind your ear or inside your elbow and wait 24 hours before rinsing it out.

If no reaction occurs during that time period, then it should be safe for you to use the product on your entire head.

Choose Mild Shampoo

Excess dye left on the scalp after dying can cause irritation and itching if not washed away properly.

To avoid this problem, choose a mild shampoo that does not contain sulfates or any other harsh chemicals – this will help ensure that all of the excess colours are removed from your hair without irritating your scalp further.

Avoid Semi-Permanent Hair Dye

Semi-permanent dyes often contain more potent ingredients than permanent dyes, which means they are more likely to cause an allergic reaction in those with sensitivities or allergies to certain chemicals found in hair dyes.

If you think you may be sensitive or allergic, opt for a permanent hair colour instead; these generally contain fewer potentially irritating ingredients and will also last longer than semi-permanent colours.

Recognize Allergy Symptoms Early

It’s important to know what signs indicate an allergy so that you can take action quickly if needed.

Common symptoms include redness and swelling at the site of application; itchiness; hives; difficulty breathing; tightness in the chest; and nausea or vomiting – any sign of an allergic reaction should be taken seriously and medical attention sought immediately if necessary.

Consider Professional Help

If you are unsure about how best to proceed when it comes to colouring your own hair due to potential allergies or sensitivities, seek professional help instead!

A qualified stylist will be able to advise on which products would suit you best based on their experience and expertise – plus, they’ll also be able to provide a much better finish than DIY home kits!

Bottomline

While getting a new hair colour can be fun and exciting, it’s important to be aware of potential allergies associated with chemically produced dyes like PPDs and PPDSs.

Be sure to read labels carefully before purchasing products and always perform a patch test before full application just in case!

If any signs of irritation occur after application, stop use immediately and seek medical attention for proper evaluation and treatment options.

With these tips in mind, hopefully, you can avoid experiencing an uncomfortable allergic reaction while still enjoying the results of your new look!
