Semi-permanent hair dye is a type of hair dye that lasts for a shorter period of time than permanent hair dye, typically lasting for 6-12 washes. It is a good option for people who want to try a new hair color without committing to a permanent change. Semi-permanent hair dye is also less damaging to hair than permanent hair dye, as it does not contain ammonia or peroxide. It is available in a wide range of colors, making it a versatile option for people who want to achieve a variety of looks.
One of the main benefits of semi-permanent hair dye is that it is less damaging to hair than permanent hair dye. This is because semi-permanent hair dye does not contain ammonia or peroxide, which are two chemicals that can damage hair. Semi-permanent hair dye also does not penetrate the hair shaft as deeply as permanent hair dye, which means that it is less likely to cause hair breakage.
