Regular application of hair dye can have potential side effects on both the hair and the scalp. Here are some of the possible effects according to Healthline.
Scalp irritation: Hair dyes contain chemicals that can irritate the scalp, leading to itching, redness, and a burning sensation.
Some people may develop an allergic reaction, resulting in more severe symptoms like swelling and hives.
Allergic reactions: Hair dye ingredients, such as paraphenylenediamine (PPD), can cause allergic reactions in some individuals.
Symptoms may include itching, rash, swelling, or even difficulty breathing. It’s important to perform a patch test before applying the dye to the entire scalp.
Hair damage: The chemicals in hair dye can strip the hair of its natural moisture, making it dry, brittle, and prone to breakage.
Over time, frequent dyeing can lead to hair damage and loss of shine.
Scalp sensitivity: Some individuals may have a sensitive scalp that reacts strongly to the chemicals in hair dye, resulting in increased discomfort and irritation.
Chemical burns: If hair dye is left on the scalp for too long or if it is applied incorrectly, it can cause chemical burns.
This can result in pain, blistering, and damage to the scalp.
To minimize the potential side effects of hair dye, it is advisable to:
Follow the instructions provided with the dye and perform a patch test before each application.
Use hair dyes that are labeled as gentle, ammonia-free, or natural to reduce the exposure to harsh chemicals.
Avoid overlapping previously dyed hair with new dye to prevent excessive damage.
Provide proper care to the hair, such as using conditioning treatments and minimizing heat styling, to maintain its health.
If you experience severe or persistent side effects from hair dye, it is recommended to discontinue its use and consult a healthcare professional or dermatologist for guidance.
