Is Laser Hair Removal Permanent?
No, in a nutshell. Using lasers, new hairs cannot grow by heating the hair follicles. After shaving or waxing, the hair follicles are in a dormant state for a longer period of time. There will be fewer and lighter hairs when they grow back because it will take longer for them to grow back.
Despite laser hair removal being marketed as a “permanent” method, it only reduces the number of unwanted hairs in a given area. This is not a permanent solution.
How does laser hair removal work?
Radiation is mildly delivered with the help of laser beams. Laser beams damage hair follicles by heating them up.
Just beneath your skin are your hair follicles. These are where new hair is produced. Hair production is temporarily halted when follicles are destroyed.
Waxing, tweezing, and shaving remove hair above the surface while tweezing removes hair below it. Neither method targets hair follicles.
For laser hair removal to be effective, follow-up sessions are needed. How many maintenance sessions are needed depends on the individual. In most cases, a laser therapy session requires four to six sessions, according to the Mayo Clinic.
In addition, these treatments must be spaced out over a period of six weeks, so that a full period of nine months is needed.
The number of hairs will likely decrease with every session. Both the texture and color of remaining or newly grown hair will be lighter. After your initial session, the number of hairs is expected to drop by 10 to 25 percent. Your hair will reduce at a variable rate after that.
Further, you will likely need to schedule maintenance sessions from time to time for the best results. Hair follicles cannot regenerate as a result of these. After your full initial round of laser treatment, you may need one or two maintenance sessions within a year.
However non-permanent laser hair removal may be, it is still one of the most effective ways to slow the growth of new hair for some time.
A dermatologist can also discuss electrolysis and needle epilators with you as long-term hair removal options.
You can remove hair at home without undergoing medical procedures that are not permanent anyway if you don’t want to undergo such procedures.
