Hair grease is a thick, oily product used to style and hold hair in place, often providing a shiny, slicked-back look. It's typically made from petroleum-based ingredients or natural oils. Hair grease is particularly popular for creating vintage hairstyles and managing coarse or unruly hair. Think of it as a heavy-duty styling agent. While it can be effective for certain styles, it's important to use it sparingly to avoid build-up. Many modern alternatives offer similar hold without the heavy feel.
