Chemistry Basics

• Matter is defined as anything that occupies space (volume) and has mass (weight).
• A molecule is composed of two or more atoms joined chemically.

Types of Chemistry

• Inorganic chemistry studies substances that do not contain carbon.
• Organic chemistry studies substances that contain carbon.

Chemical Reactions

• Ionization is the process of separating a substance into ions.
• An ion is an atom or molecule that carries an electrical charge.
• Oxidation is a chemical reaction that combines an element or compound with oxygen to produce an oxide, which can be either the addition of oxygen or the loss of hydrogen.

Hair Care Products

• Conditioners come in two types: instant (also known as rinse-out) and leave-in.
• Instant conditioners typically remain on the hair for 1 to 5 minutes before being rinsed out.
• Leave-in conditioners and thermal protectors can be left in the hair without rinsing.
• Medicated conditioners are formulated to control minor dandruff and scalp conditions.
• Medicated shampoos contain medicinal agents for controlling dandruff and other scalp conditions.
• Neutralizing shampoo helps to rebalance and restore the pH level of the hair by neutralizing any alkali or unwanted residues after chemically relaxing the hair.
• Liquid-dry shampoos are liquid shampoos that evaporate quickly and do not require rinsing.
