Straight hair is a type of hair texture that lies flat and smooth without any curls or waves. It can vary in thickness and shine, and is often considered sleek and easy to manage. Many people with straight hair enjoy its versatility, as it can be styled in various ways, from simple ponytails to elegant updos. Some famous individuals, like Jennifer Aniston and Emma Watson, are known for their beautiful straight hair. To maintain straight hair, many use products like serums and heat protectants to keep it healthy and shiny. Regular trims also help prevent split ends and maintain a polished look.
