The question is often asked to Leenarts, but according to the dermatologist it is a stubborn fable. “Your hair does not become fatter if you wash it often. That would mean that shampoo would have an effect on the sebum production. Shampoo cleans the scalp and removes sebum and remnants of styling products. The sebum production is regulated by hormones. Shampoo has no influence on that,” says Leenarts.

Although a daily wash is not necessarily harmful to the scalp, the scalp can get dry or irritated if you wash it too much. “A dry or irritated scalp can produce more sebum, making the hair fat faster. If you have a dry scalp? Then the shampoo can be skipped once.”
Personal needs
Every scalp has – just like the skin of the body – personal needs. According to Leenarts, it is therefore important to choose a shampoo that matches the hair type and scalp. “Watch out with aggressive shampoos that have a drying effect.”
On social media, cheap shampoos from the supermarket have been getting the wind for a while. But is a shampoo of dozens of euros really better for the hair? “The price of a shampoo does not always say anything about the quality of the product. Some expensive shampoos contain many aggressive ingredients, such as sulfates or perfume. Some scalp types can be sensitive to this.”
With one person the hair gets fat after a day, while the other only has to wash it after a week. According to the dermatologist, that also has to do with the sebum production. “The hormone production is different for everyone, so how much sebum someone is creating is very personal. For example, teenagers also suffer from a fatter scalp, making the hair fat faster. That also applies to people with a fatter skin hype.” Other factors, such as stress, nutrition and seasonal changes, can also have influence.

So our locks do not have to be washed every day, but what is common? “It depends on the hair type and lifestyle. An extra wash, for example, doesn’t hurt if you sport and sweat a lot of sweat several times a week, or use a lot of styling products every day. But most people make it with two to three washes a week.”
Getting used to washing
Leenarts states that it is not scientifically proven that you can ‘get used to’ hair to the daily washing. “The hair cannot get addicted to washing or shampoo. It only has to do with the sebum production. Significant glands have its own rhythm. If you wash your hair daily, and you try to reduce this, it may take a while before your hair feels less fat. That is a transitional period, no getting used to.”
Do you like to jump every day in the shower for a wash, but would you rather not wash your hair every day? “Try the hair to wash the day with water. That not only gives a fresh feeling, the hair also makes it cleaner.” Dry shampoo on the intervening days is also a solution. “However, do not use it too often. It is not a replacement for shampoo,” Zoertarts warns. “If you spray too much dry shampoo in the hair, the remaining particles can irritate.”
Incorrect use of products
Incorrect use of products can also cause fatter hair. Conditioner is also used on the scalp, while it is only suitable for points. “Then people have to wash their hair again more often. It is really the intention that everyone uses conditioner only on the points. This part of the hair is the most damaged and therefore needs the most care.”
