The main purpose of shampoo is to remove dirt and oil from the surface of the hair fibres and the scalp, while the main purpose of conditioner is to ensure that the hair is smooth for combing. Some commercial shampoos may also have additional components to control dandruff and condition hair.

Look for shampoos that contain lauryl sulfates or sulfosuccinates for a deep clean. Too many conditioning agents should also be avoided, as these can contribute to an abundance of oil, even after a wash. Shampoos with natural ingredients like tea tree oil are also worth a try.

Some of the most important chemicals in your shampoo are the surfactants. Commonly used as detergents and emulsifiers, surfactants like sodium laureth sulfate and ammonium laureth sulfate are the parts that actually wash your hair. These ingredients break the bond between hair and the dirt.

The oils in your hair adapt to what shampoo you’re putting in it. So switch off every few weeks to reinvigorate your tresses. “I like to recommend to clients changing [brands] after the shampoo is finished,” Aviza says. “Or work with two shampoos at all times.

So in answer to the question ‘should I regularly change my shampoo and conditioner? ‘ the answer is: Change your shampoo and conditioner when your hair tells you to. Don’t just reassess the products you’re using at the end of each bottle.
