Bleach

Bleach, in the context of hair care, refers to a chemical product used to lighten or remove the natural color of the hair. It's a powerful oxidizing agent that works by breaking down the melanin (the pigment responsible for hair color) in the hair shaft. Bleach is used to lighten the hair, making it significantly lighter than its natural color. It's commonly used to achieve blonde or lighter shades. Unlike temporary hair color or toners, bleach causes a permanent change in the color of the hair.

Cautions:
Bleaching can be harsh on the hair, potentially causing damage, dryness, and breakage. It's important to follow proper application and aftercare techniques. After bleaching, it's common to use a toner to achieve the desired shade. Toners can help neutralize unwanted tones, such as brassy or yellow hues.

Bleached hair requires special care to maintain its health and color. This includes using sulfate-free shampoos and conditioners, using hair masks or deep conditioners, and avoiding excessive heat styling. When applying bleach, it's crucial to avoid overlapping onto previously bleached sections, as this can cause uneven lightning and potential damage.
