Hair dyeing issues


I would like to ask Dr.
Wu...
Last night, I dyed my hair myself and I'm not sure what happened (I usually dye my hair 2-3 times a year at a salon, and I also have a habit of using at-home hair dye to cover my gray hair).
After dyeing my hair last night, I felt very unwell.
I started dyeing around 9-10 PM (full head), and since it was late, I waited until my hair dried before rinsing it out (around midnight).
However, after washing and drying my hair, I felt extremely uncomfortable.
Initially, when applying the dye, I experienced a tingling sensation on my scalp.
After rinsing, I had severe pain in my lower left back (I’m not sure if it’s my kidney, but the pain has persisted), and I also have ongoing pain on both sides of my chest (in the area around my armpits and upper chest), which has continued throughout the day...
I have never experienced such pain from dyeing my hair before (except for a previous incident when I had my hair bleached for my wedding, which caused intense burning and stinging on my scalp)...
I’m not sure what the cause could be...
If I need to see a doctor, which specialty would you recommend? Thank you for your help, doctor.

When it comes to hair dye reactions, it's essential to understand the potential side effects and when to seek medical advice. Based on your description, it seems you experienced discomfort after dyeing your hair, which is not uncommon, especially if you have sensitive skin or if the dye contains harsh chemicals.

Firstly, the symptoms you described, such as a stinging sensation on the scalp during the dye application and subsequent pain in your back and chest, could indicate a few different issues. The stinging sensation on the scalp might suggest a mild allergic reaction or irritation from the hair dye. Hair dyes often contain chemicals like ammonia, peroxide, and various colorants that can cause skin irritation or allergic reactions in some individuals. If you have a history of sensitivity to hair products, this could be a contributing factor.

The pain you are experiencing in your back and chest is concerning and may not be directly related to the hair dye itself. It's crucial to consider that the discomfort in these areas could stem from various causes, including muscle strain, anxiety, or even a more serious condition. Given that you mentioned this pain has persisted, it is advisable to seek medical attention.

In terms of which specialist to consult, I recommend starting with a visit to a dermatologist. A dermatologist can evaluate your scalp and any potential allergic reactions or irritations caused by the hair dye. They can also provide guidance on how to manage any skin reactions and recommend suitable products for sensitive skin.

If the pain in your back and chest continues or worsens, it would be prudent to see a primary care physician or even a specialist in internal medicine. They can conduct a thorough evaluation to rule out any serious underlying conditions, such as issues related to your kidneys or cardiovascular system. Given your symptoms, it is essential to address these concerns promptly.

In the future, to minimize the risk of adverse reactions when dyeing your hair, consider the following precautions:
1. Patch Test: Always perform a patch test before using a new hair dye product. Apply a small amount of the dye to a discreet area of skin and wait 48 hours to see if any reaction occurs.

2. Choose Gentle Formulations: Look for hair dyes that are labeled as "gentle," "ammonia-free," or "hypoallergenic." These formulations are less likely to cause irritation.

3. Follow Instructions Carefully: Ensure you follow the manufacturer's instructions regarding application time and method. Avoid leaving the dye on for longer than recommended.

4. Consult a Professional: If you frequently experience discomfort or have concerns about dyeing your hair, consider visiting a professional stylist who can use products suited to your skin type and hair condition.

5. Stay Informed: Educate yourself about the ingredients in hair dye products. If you have known allergies, check the ingredient list to avoid any harmful substances.

In conclusion, while hair dye reactions can be common, your symptoms warrant further investigation. A dermatologist can help address any scalp issues, while a primary care physician can evaluate the pain in your back and chest. Don't hesitate to seek medical advice, as it's better to be cautious when it comes to your health.
