Are split ends and dead the same?

Split ends and dead ends are not the same. Split ends are when the hair shaft splits into two or more strands. Dead ends are when the hair shaft is damaged and no longer receives nutrients from the scalp. Split ends can be caused by a variety of factors, including heat styling, chemical treatments, and environmental factors. Dead ends can be caused by the same factors, as well as by aging. Split ends can be treated with a variety of products, including serums, oils, and masks. Dead ends cannot be treated and must be cut off.
