The Vietnamese word "gầu" primarily means "dandruff" in English. Dandruff refers to the small, white flakes of skin that often appear on the scalp. It can be a common issue for many people and is usually harmless, though it can sometimes be itchy or annoying.
In a more advanced context, you can discuss treatments or causes of "gầu": - Các sản phẩm trị gầu rất phổ biến trên thị trường. (Anti-dandruff products are very popular on the market.) - Gầu có thể do nhiều nguyên nhân như căng thẳng hoặc da khô. (Dandruff can be caused by many factors such as stress or dry skin.)
While "gầu" mainly refers to dandruff, in some contexts, it may also be used to describe flaking skin in general, but this is less common.
