This page will answer your questions before using hair dyes.

What are hair dyes?

Hair dyes are classified as cosmetic substances that change hair color through a series of chemical reactions affecting the hair's natural color. There are several types, including permanent, semi-permanent, and temporary dyes.

• Temporary dyes: These only cover the surface of the hair and do not penetrate the hair shaft. They generally last for one or two washes.

• Semi-permanent dyes: These typically penetrate the hair shaft and may last for 5 to 10 washes, like natural henna.

• Permanent (oxidative) dyes: These contain several mixed substances that cause permanent changes in hair color. They are among the most common types and include colorless agents like aromatic amines (ammonia) and phenols that react with hydrogen peroxide. These dyes may cause damage to the hair, eyes, and skin if used incorrectly, resulting in:

• Hair loss.

• Scalp irritation.

• Redness.

• Itching.

• Skin burns.

• Breathing issues.

• Facial swelling.

What are the correct usage methods?

• Preferably, choose a color close to your natural hair color, within three shades, as selecting a significantly lighter color may contain a large amount of peroxide, which can damage dark hair.

• Test the product on a small area of skin for two days, and if there is a rash, do not use the dye.

• Protect your hands with gloves.

• Avoid using dye on eyebrows and eyelashes.

• Follow the product instructions.

• Keep the dye out of the reach of children.

• Avoid hair dyes during the first three months of pregnancy.

• Do not leave the dye on your hair longer than the instructed time.

• If you experience burning, redness, irritation, hair loss, or breathing difficulty, wash your hair immediately and consult your doctor.

• Rinse your hair thoroughly after the time specified.

• Wash your hands after finishing.

• Store the product appropriately according to instructions.

• Avoid mixing it with other chemical substances.

• Use shampoo and conditioner specifically for dyed hair.

• When exposed to the sun, protect your hair with a leave-in conditioner containing zinc oxide or cover your hair.
