Shampoo: true and false

Old wives tales are often hard to shake off. To find out everything there is to know about shampoo and how to use it, take a look at our true-and-false guide.
 
Using shampoo every day damages your hair: False
"We don’t recommend you wash your hair every day, but it won’t do it any harm. Your hair is protected by a hydrolipidic film. If you wash your hair every day, you will end up removing this layer, leaving your hair more vulnerable to external aggravations." Though many of you wash your hair every day and it doesn’t have any effect on your hair, it is best to try and space out your hair washes.
 
You should change your shampoo often: True
"Maybe not too often but it is a good idea to have two different shampoos and alternate between them depending on your hair’s condition." That way you can be sure you’re giving your hair everything it needs. For example, if you have fine hair that’s dry as well, you can use nourishing masks as well as volumising treatments.
You should wash your hair with shampoo twice in a row: False
It depends how clean your hair is. If you wash your hair every day or your hair isn’t very dirty, one wash is plenty. However, if your hair is really dirty, it might be a good idea to wash it twice. « But use less shampoo the second time for a lighter wash."
 
You should massage your scalp when applying shampoo: True
"And when we say 'massage', we mean massage, not scratch. Scratching your scalp could cause irritation." This beauty step will help promote blood circulation, lifting your hair off your scalp and leaving it shinier and more resistant.
Shampoo can be used on hair AND the scalp: True
Your hair isn’t the only thing a shampoo can be used for. When your hair secretes sebum, this takes place on your scalp. It's therefore important to make sure you wash your scalp as well.
