What chemical can you use to lighten your hair or wash your cloths?

Hydrogen peroxide is commonly used to lighten hair because it breaks down the melanin in the hair shaft. For clothes, chlorine bleach is often used to remove stains and brighten whites by breaking down pigment molecules.


Dose powder bleach lighten hair without cream peroxide?

Powder bleach alone will not lighten hair without cream peroxide. Cream peroxide is necessary to activate the bleaching process and lighten hair effectively. Mixing powder bleach with cream peroxide creates a powerful bleaching agent that can lighten hair several shades.


Why can semi-permanent color not lighten hair?

Semi-permanent color deposits color onto the hair shaft but doesn't contain ingredients that can lighten the hair's natural pigment. It lacks ammonia or peroxide, which are needed to lift the hair's cuticle and lighten the hair.


Does temporary hair color cause a physical or chemical change in the hair shaft?

Temporary hair color causes a physical change by coating the hair shaft with color molecules that temporarily adhere to the hair surface. This coating washes out gradually over time without affecting the structure of the hair shaft.


How does ammonia help in hair dye?

Ammonia helps in hair dye by opening up the hair cuticle, allowing the dye to penetrate the hair shaft and deposit color more effectively. It also helps to lighten the natural hair color and create a base for the new color to adhere to. Additionally, ammonia helps in the chemical reaction that occurs between the dye and the hair pigment.
