How is chemistry related to the hair industry?
Chemistry in Hair Color Stylists often use bleach to lighten hair, and this works because bleach reacts to hair’s melanin. Melanin gives hair its color. When the bleach gets to it, your hair loses its pigment. Permanent hair coloring is the process of embedding small molecules into the hair’s shaft.
Why is it important to understand basic chemistry as a successful cosmetologist?
Chemistry, Anatomy, and Other Sciences Brushing up on chemistry will help keep your clients safe when you use products with chemicals to do perms, nails, facials, and of course, color and hairstyling.

How does chemistry play a part in hair colourist?
Peroxide is used as the developer or oxidizing agent. The developer removes pre-existing color. Peroxide breaks chemical bonds in the hair, releasing sulfur, which accounts for the characteristic odor of hair coloring products. As the melanin is decolorized, a new permanent color is bonded to the hair cortex.
How is science used in hairdressing?
The amount of acid or base in a liquid is measured on the pH scale. For hairdressers, understanding the pH balance between the acids and bases found in dyes, shampoos and conditioners is vital. In an acidic solution, cuticle cells shrink and harden, making hair strong and stiff, but potentially brittle.
How does chemistry influence the production of cosmetics?
There are many chemical principles involved in developing and manufacturing personal care items. For example, oil-soluble ingredients in lotion prevent moisture from escaping through the skin or attracting additional moisture, and emulsification combines the oil and water-based components.

What type of chemical reaction is hair color?
This is known as oxidation colouring and uses peroxides and couplers. Permanent hair dyes – these contain colourless dye precursor molecules that react with hydrogen peroxide inside the hair shaft to produce coloured molecules. The precursor molecules vary but para-phenylenediamine (PPD) is a common one.
Which chemical is used in hair dye?
Oxidative hair dyes contain the oxidizer hydrogen peroxide and a dye intermediate such as paraphenylene-diamine (PPD), resorcinol, and aminophenol. PPD is an aromatic compound, widely used in almost all hair-coloring formulations, because oxidation of this substance with couplers produces colored reaction products.
Why is hair color a chemical reaction?
The reactions which produce the dyes are carried out at an alkaline pH, and in many cases this is provided by the presence of ammonia in the formulation. The ammonia causes the cuticles of the hair to swell, which then allows the dye molecules to pass into the hair and induce permanent colouring.
