What Are the Hazards of Dyeing Hair on the Body?

Hair dyeing may pose hazards such as disease induction, skin allergies, poisoning, lead poisoning symptoms, and hair damage. Here are the specific reasons:

1. Cause Diseases: Hair dyes contain chemical components that can affect hematopoietic stem cells and are carcinogenic substances. Therefore, it is advisable to be extra cautious.

2. Cause Skin Allergies: Hair dyeing can also lead to allergies, which is a common occurrence. Initially, the allergic reaction may not be apparent, but it can become more severe after several dye sessions.

3. Poisoning: Long-term use of hair dyes can lead to poisoning. Even if only 1% of the dye is absorbed into the body through the skin, it can accumulate and cause harm. The chemical substances in hair dyes can bind to certain cells, damaging the deoxyribonucleic acid (DNA) in the cell nuclei and causing cell mutations. This can lead to skin cancer, bladder cancer, leukemia, and other diseases. Therefore, it is important to be vigilant and avoid these potential health risks.

4. Lead Poisoning Symptoms: Hair dyes also contain lead acetate, which has a lead content 5 to 10 times higher than that of household paints and pigments. Once lead enters the body, it is difficult to excrete, leading to accumulation and poisoning. Symptoms of lead poisoning include dizziness, headache, fatigue, numbness in the limbs, leg cramps, abdominal pain, and other symptoms. Lead can also damage the liver, kidneys, and brain, potentially leading to the loss of labor capacity in severe cases.

5. Hair Damage: The process of hair dyeing can disrupt the water balance in the hair, leading to denaturation and reduction of proteins. This can make the hair brittle and prone to breakage, causing it to lose its natural softness, elasticity, and glossy beauty.
