Split ends are a common hair problem that can make hair look dry, frizzy, and unhealthy. They occur when the ends of the hair shaft become frayed and split into two or more strands. Split ends can be caused by a variety of factors, including heat styling, chemical treatments, and environmental damage.
There are a few different methods you can use to check for split ends. One way is to hold a single strand of hair up to the light and look for any frayed or split ends. Another way is to run your fingers down the hair shaft from the roots to the ends. If you feel any rough or bumpy areas, it is likely that you have split ends.
