Hair Care and Chemistry Basics

Hair Care Terms

• Conditioners are chemical agents that deposit protein or moisturizers in the hair.
• Conditioning shampoos, also known as moisturizing shampoos, are mild cream shampoos that contain moisturizing agents (humectants) to "lock in" or draw moisture into the hair.
• Dry or powder shampoos are used to cleanse the hair without water.

Chemistry Basics

• An element is the simplest form of chemical matter, containing only one type of atom.
• Elemental molecules consist of two or more atoms of the same element in fixed proportions, such as oxygen (O2).

Chemical Reactions and Mixtures

• Emulsions are mixtures of two or more immiscible substances united with the aid of a binder or emulsifier.
• Endothermic reactions are chemical reactions that require the absorption of energy or heat from an external source.
• Exothermic reactions are chemical reactions that release energy in the form of heat.

Hair Care Products

• Hair tonics are grooming aids designed to stimulate the surface circulation of the scalp, remove loose dandruff, or impart manageability, shine, and control to the hair.
• Instant conditioners, also known as rinse-out conditioners, typically remain on the hair for 1 to 5 minutes and are then rinsed out.

Chemistry Concepts

• Inorganic chemistry is the study of substances that do not contain carbon but may contain hydrogen.
• Ions are atoms or molecules that carry an electrical charge.

Chemical Reactions

• Exothermic reaction: involves the release of energy in the form of heat through certain chemical reactions.

Hair Care

• Instant conditioners: conditioners that typically remain on the hair from 1 to 5 minutes and are rinsed out.
• Alternative name for instant conditioners: rinse-out conditioners.

Chemistry

• Ionization: the process of separating a substance into ions.
