Hair removal from a destroyed hair follicle is permanent. However, people who undergo hair removal can expect that some hair in the targeted area will grow back. Over time, it is possible to treat the area again to reduce the number of hairs that regrow. In some cases, it may even be possible to eliminate all hair, making grooming easier and less frequent.
Whether or not hair grows back depends on numerous factors, including biological aging, the type of hair that regrows, supplements, as well as the hormonal and chemical changes each person experiences. When you complete a course of laser hair removal, you can expect:
- Fewer hairs
- Thinner hair in the treatment area
- Less frequent shaving or waxing/slower growing hair
Most people find that when hair regrows, it is lighter and less noticeable than it was before. This is because the laser may damage the hair follicle even when it doesn’t destroy it. It can be difficult to destroy every single hair follicle, so most people will see some hair regrowth.
When hair regrows, it is possible to treat it again, so people who want to remove all the hair may need ongoing treatment. You should plan for a maintenance session 1-2 times per year. Some people do not need maintenance sessions even yearly. Others need to come more frequently.
