How Many Laser Hair Removal Treatments For Underarms?
Most physicians will advocate that an average of 6 sessions minimum are needed to see any kind of real results. As for Satori Laser, while it is possible to see results as early as after one session, it is more likely that you will need 4 to 7 of them to actually achieve any type of semi-permanent hair reduction. It is also important to schedule the treatments at regular time intervals. On average between four and six weeks. So that the laser can catch any hairs that were dormant in the previous session. If you schedule the treatments too far apart you risk completely missing entire cycles of hair growth and never catching certain hairs.
After the first session, it is possible to see a 5-20% difference in hair growth. By the sixth session, this result can go as high as 90%, so it is well worth persevering with the treatments. Results really do depend on different factors, such as skin type and hair color and type, and this is something your physician will be able to evaluate with you on a case by case basis.
Why do some areas require more sessions than others?
Hair grows in cycles and treatment is only effective when it attacks hair during the growth period. This period may only last a couple of weeks. After that, the hair goes into a resting period that can last up to 24 weeks (depending on the area of the body treated). It is important to schedule repeat treatments in order to catch as many hairs as possible in their growth period. This is also the reason that touch-ups may be required a year or so after treatment has been finalized. For example, while an armpit hair will complete a cycle within 5 months, a leg hair can take up to 12 months.
Another reason for more sessions may be hormonal. Areas such as the upper lip and chin are generally more hormonally-ruled than the arms or legs. This means that these areas may require more sessions than an arm would, as hairs may be more or less active due to hormonal fluctuations. Often after important hormonal changes, such as pregnancy or menopause, long-term dormant hair follicles suddenly become active, causing an influx of hair growth. This does not mean that hormonal changes revert the results of laser treatment, just that hairs that were never treated before suddenly start to grow. Depending on a number of hairs that are affected your physician may advise a few touch up sessions or a full treatment schedule.
Why would I need a touch-up session after the initial treatment?
There are several reasons for this. One is that there may be patches of hair that were not treated during the initial sessions and are now in full growth period. A touch-up session or two every year or so can help maintain your hair-free skin. The other main reason is, as mentioned above, hormonal, causing dormant hair follicles to become active and hair to grow. Unless there is a large hair regrowth, a couple of touch up sessions will take care of this for you. This is really where the semi-permanence of laser hair removal treatment comes into play. While the treatment can target multiple hairs at a time and can, therefore, cover a large area of skin rapidly. It cannot target each hair at its optimal growth period during a session. This does not mean that correctly treated hairs grow back. But that other hair come out of their resting period and start to grow. These are new hairs that were not treated previously.
As stated earlier in this article, each person is different and your physician will explain this to you. But you should assume that you will need at least 4-8 regularly scheduled sessions to see results and also that you will probably need to budget for another session within a year or two of your initial treatment. At Satori Laser we offer to touch up services, and it will usually be cheaper than the treated body part’s original price.
