What are Lice?
Lice are tiny insects that live on human hair and feed on blood from the scalp. They are highly contagious and can quickly spread from one person to another through direct contact. Lice eggs, also known as nits, are glued to the hair shaft and can be difficult to remove. Adult lice are about the size of a sesame seed and are usually found close to the scalp.
How Do Hair Straighteners Work?
Hair straighteners use heat to smooth out and straighten hair. They work by applying heat to the hair shaft, which breaks down the hydrogen bonds that give hair its shape. This allows the hair to be reshaped and styled.
Can Lice Survive a Hair Straightener?
Lice cannot survive a hair straightener because they are sensitive to heat. The recommended temperature for killing lice on hair is 130°F (54°C) or higher, which is easily achieved with a hair straightener. However, it’s important to note that lice eggs, or nits, are more resistant to heat than adult lice. Nits may require higher temperatures or a longer exposure time to be effectively killed.
