If your hair gets greasy quickly, you're not alone. In most cases, it's simply because your scalp produces more sebum (its natural oil) than others. Genetics play a big role, but your hair type, styling routine, and even how often you wash your hair can all influence how quickly oil becomes noticeable.
Fine, straight hair tends to look greasy sooner because oil can travel more freely from the scalp down the hair shaft. Heavy styling products applied at the roots can also make hair appear oily faster.
Surprisingly, washing more often isn't always the answer. Too much shampooing can strip away the scalp's natural oils, which can lead it to produce even more sebum in response.
If your roots become oily fast, focus on keeping your scalp clean without over-cleansing. Choose a shampoo that's suited for your scalp, use styling products primarily through the mid-lengths and ends, and use a dry shampoo netweem wasjes to absorb excess oil and extend your style.
