You can expect to be hairless in the treatment region for between 1 to 3 weeks after your first treatment. This is the reality for every laser hair removal patient. Keep in mind that everyone will require a number of follow-up treatments before they achieve permanent hairlessness in the region. Seeing hair regrowth in the weeks following your laser hair removal is to be expected, even though the regrowth will be less than if you did not have the treatment.
This is an important distinction to make when discussing how long does laser hair removal last after first treatment. You can expect to see regrowth there within weeks, but this is natural and is not an indication that the treatment is ineffective or has been given improperly by your technician. Every laser hair removal patient will require multiple laser hair removal treatments before no hair regrowth is seen.
The type and density of the hair being treated will factor into how quickly you see this hair regrowth. For example, men who are treating a dense area of hair will see regrowth more quickly AND require more additional treatments before achieving desired results. Each patient should come into our clinic with an understanding that their unique physiology and the specifics of the area being treated will determine how many follow-up treatments are required.
How long does laser hair removal last after the first treatment? As we’ve explained clearly here, it depends on the individual and the nature of the treatment, but you can expect to see regrowth there within 1 to 3 weeks after your first treatment.
