What’s the point of letting your hair grease out?

Forgoing hair washing completely for two weeks in order to have to wash your mane less often afterwards – a widespread beauty myth that probably very few people have actually tried out so far. But does the whole procedure really make sense? Tikbow asked the expert what the temporary renunciation of shampoo and Co. really brings.

That hair becomes greasy is a completely natural process, finally, the scalp produces sebum – for some people more, for others less. It is said, however, that you can have a decisive influence on how quickly your hair becomes greasy by washing it. Washing your hair every day, for example, is supposed to accelerate the greasing process, while not washing your hair for a long time has the opposite effect. But is this true? We asked Dr. Timm Golüke, a dermatologist from Munich, how much there really is to this myth.

Does it do any good to let the hair grease out?

"No, the scalp does not think! ", clarifies the dermatologist. According to him, it is a misconception that the skin gets used to being washed less frequently – and consequently becomes less greasy. It’s like the skin on your face, which doesn’t start to produce fat if you don’t put any cream on it,” explains the expert.

Who should not let their hair get greasy under any circumstances

How often you need to wash your hair depends on two factors: Hair structure and scalp type. The latter in particular is crucial for the hair washing detox: "Especially if you have a very oily scalp, it is not advisable not to wash your hair for two weeks", clarifies Dr. Golüke. People who are prone to this even risk scalp eczema by not washing their hair for a long time. For all others, the procedure is not dangerous, but from a dermatological point of view it is not sensible.

This is how often you should wash your hair

Above all also in view of the hygiene the whole is not meaningful according to expert. It is better to keep a general hair washing cycle of two to three days – however, this also varies from scalp to scalp, as dermatologist Tikbow explains. At least for the hair it is advisable not to reach for the shampoo bottle every day, otherwise the mane quickly becomes dry and straw-like. But equally inadvisable is to do without hair cleansing for a long time.
