The true reality that most clinics will not lead with is that laser hair removal is not really permanent and that is why there are laser hair removal maintenance sessions and scheduled touch-ups. The technology, even by the FDA itself, was not cleared to permanently remove hair, but was limited to permanent hair reduction. The good news? With a proper maintenance plan, your outcomes can be near permanent in decades. This blog will deconstruct precisely how frequently you will require laser touch up sessions, what causes previous growth, and how to plan on it, without the industry jargon.
Why Laser Hair Removal Is "Permanent Reduction" Not "Permanent Removal"
This is the unique difference, which has become a part of FDA language since the late 1990s, and is the most crucial aspect to know about laser hair removal. According to the FDA, permanent hair reduction is a permanent, steady decrease in the number of hairs that regrowth, at 6, 9 and 12 months following a course of treatment. It does not specifically imply zero regrowth.
Why? Lasers destroy the hair follicle by taking over the light into melanin pigment. This kills the majority of target follicles, not all. Other follicles never come out of dormancy and instead undergo dormancy but eventually the stem cells that survive can reactivate.
And on top of this, there is a constant secretion of hormones (testosterone, oestrogen, androgens) in your body that can activate latent follicles to grow, especially in high hormone sensitive regions such as the face, underarms and the bikini line. It is the reason why laser hair removal long term success is a matter of continuous follow-up and not a cure.
Dermatologist Insight: According to most trichologists, laser has an average of 70-90 percent of hair reduction following the first round. The rest 10-30%, together with the hormonally-stimulated new growth, is precisely what maintenance sessions are all about.
How Long Do Laser Results Last After Your Initial Course?
The average patient will experience 1-3 years of near-hair-free, smooth results after your first 6-8 session course before the first touch-up will be needed. This also depends on three factors greatly, which are: the area of the body being treated, your skin-hair contrast and your hormonal profile.
The longest-term effects are usually on legs and arms, 2-3 years to any significant regrowth. The bikini region and underarms are in the middle, with an average of 12-18 months. The most hormonally sensitive areas of the face are the upper lip and chin, and some of the patients may require touch-up within 6-12 months.
In the case of Indian skin types, with their thick, dark, coarse hair and medium-deep skin tones, the results are usually very good, but the very same thing that causes lasers to work also causes early regrowth to be pigmented and noticeable.

Note: These are averages, not guarantees. You may do it in your own time once you have been examined by a scalp-skin-hormonal test with your treating dermatologist.
