There are several reasons why you need to wait between laser hair removal sessions. The first one is that you need to let your skin rest and regenerate after a laser treatment. Indeed, UV rays are quite aggressive to the skin and too much of it could lead to skin damage.
The second reason is follicle regeneration. Indeed, some follicles will be more resistant than other to laser. Thus, they may need more than one session to be irreversibly damaged.
When a hair follicle is not completely out of service, it will regenerate and be able to grow new hair again. Repetitively targeting resistant follicles will not leave them enough time to regenerate. The third reason is of course the hair growth cycle that is different for each patient, for each area of the body and for each body hair as well.
A hair can be in the anagen phase of growth for up to six years. However, how do we know which hair is in which stage and for how long it's been in that particular stage? It's impossible to know.
Waiting six weeks between laser hair removal sessions gives time to body hairs that were not in the anagen phase to enter it. Depending on the size of the area you treat during your laser hair removal session, the appointment can last from ten minutes i.
The laser will heat up the skin around the hair a bit as well so it is possible that you experience redness and irritation. However, those should be gone within a few hours. Immediately after your session and within the next seventy-two hours, you must avoid very hot showers, the swimming pool, the gym or any physical activities that may heat up the skin.
Indeed, the heat of the laser stays under the skin for up to twenty-four hours. Avoid direct sunlight and wear SPF 50 if you expose yourself to the sun. A few weeks after your initial treatment, you may notice less hair growth and maintenance.
Indeed, the follicles shed the hairs that were in the anagen phase and that were successfully targeted. Hairs that were not in this phase will start or continue to grow. You may exfoliate your skin a week after your session of twice a week until a few days before your next appointment. Indeed, exfoliating leaves the skin a bit sensitive. Refrain from waxing or plucking. Doing so would remove the hair along with the root leaving nothing to target during your next session.
Indeed, a completely new hair needs at least six weeks to fully grow. This light generates heat, and the heat damages the follicles, compromising their ability to regrow any hair. After each session, the follicles take more and more damage. At first, they may be able to grow a bit more hair, but only feebly. Some follicles will never be able to grow hair again, and others will only be able to grow thinner hair at a point months in the future.
This thin growth is easily targeted with a maintenance treatment at that time. In the active growing cycle, your hair is producing the pigment that gives it its color, and this pigment is what the laser targets. For this reason, laser treatments are most effective on follicles that are in the active stage.
As you wait a few weeks between each treatment, more hair will move from dormant or shedding and into the active growing stage, allowing your next treatment to effectively target them. Laser hair treatments offer a convenient and effective alternative to all the messy methods of hair removal that eat up your time and give only short-lived results. The results of laser treatments are long-term, giving you smooth skin for months at a time. For some, the results can even be permanent, but even if your hair does grow back, it will be lighter and thinner than ever and will only need occasional treatment.
Laser hair removal has been available since the late s, and the technology has only improved since that time. Laser hair treatments compare very well against traditional forms of hair removal. In particular, they allow you to avoid all the negatives that come with these options as well as the problem of constant, regular regrowth.
Think of the intense pain that comes with waxing and the difficulty of getting every sticky bit off afterward. Plucking is also uncomfortable and irritatingly time-consuming as you work one painful hair at a time. Shaving is more comfortable, but it still offers a constant risk of nicks and cuts, and razor burn is an issue for both men and women. About five per cent of our hair is in this phase at any given time. The final stage is the telogen.
At this time, the hair begins to shed and the follicle is prompted to start a new cycle. The length of this stage is about days for the healthy follicles on the scalp, but other areas of the body can vary significantly. About 10 per cent of hair follicles are in the telogen phase at any given time.
Given that anagen is the most important phase for laser hair removal you can understand why not all hair is treated in any one laser hair removal treatment, and why it is important to book a package of treatments. The number and time between treatments may vary from person to person, depending on your hair type, so it is recommended to always follow the advice provided by your trained laser technician.
Our laser hair removal technicians at The Cosmetic Clinic have all received extensive training in the medical grade lasers we use. They analyse your type of hair and skin to develop the right treatment plan for you to ensure optimum results and reduce any risks.
