Diode Laser Hair Removal
Long-term hair removal has to affect hair in the active cycle of its growth, namely in Anagen. All long-term epilating methods target hair at
this stage; and since the growth cycle differs between body areas, each body area requires re-treatment at different time intervals to achieve
maximum results. The normal hair cycle is comprised of three stages: active growth -
Anagen, transition - Catagen and resting - Telogen.
Hair follicles go through these cycles in a non-synchronized manner. It is important that patients understand the hair growth cycle in order to
have realistic expectations. Table identifies percentages of hair in the Anagen and Telogen stages for various body areas. For example, over
65% of facial hair is in Anagen at any given time, while only 20% of the hair on the legs is in Anagen. This means that one cannot expect long
term epilation in a single- or even double-treatment session. Moreover, the table shows that the duration of the resting period for hair follicles
also depends on the body area. In a clinical setting, this means that the period between consecutive treatments should be determined by the
body area being treated. The numbers in the table are statistical and, therefore, may vary between individuals depending on gender, age,
ethnic origin, hormonal status, etc. The difference in follicle depth in the various body areas may also affect the treatment parameters and results.

Goals of Permanent Hair Reduction be elos Technology

Traditional methods of hair removal by laser or light source rely on photo-thermolysis to achieve permanent hair reduction. Thermal
damage to the follicle and to the hair growing structure must be sufficient for denaturizing, resulting in cessation of the normal hair
growth cycle.Using traditional systems in order to achieve photothermolysis in hair removal, there must be sufficient light absorbed by
the melanin in the hair shaft in order to produce heat in the surrounding follicle. In instances where there is insufficient absorption of light,
thermolysis cannot be achieved. This explains why poor target hair (low melanin concentration) is not successfully treated with traditional
systems. By combining both light and radio frequency current, the elos Plus Motif Vantage applicator uses two different energy sources to
thermally damage the follicle, even follicles growing poor melanin target hair such as grey, blonde and red.The optical energy abides by the
principles of photothermolysis. The diode laser pulse is absorbed by melanin in the hair shaft. Upon absorption thelight energy is converted
to thermal energy, heating up the hair shaft and dissipating heat into the follicle. Since laser is just half of the equation in elos, lower fluence
or less optical energy is used as compared to traditional systems.This has direct correlation with the reduced incidence of side effects using
the elos technology.

Realistic Expectations:

Permanent hair reduction means that when a follicle is thermally destroyed it is not able to grow a terminal hair again. Because there are
many millions of follicles that can potentially grow on the body, it is not realistic to expect that every single follicle in the treatment area
will be disabled. Over several treatments with appropriate intervals, most of the follicles that cycle through hair growth will be affected
by the elos procedure and will be critically injured so hey are permanently disabled. The follicles that are dormant or of vellus hairs are
not affected during these treatments. It is important to remember that the body can convert these inactive or dormant follicles to grow
later in life as a result of many factors: hormonal imbalance, pregnancy, menopause, disease or medications, obesity, or idiopathic causes.
This is why there can be no guarantees or promises of "all the hair gone forever" from a certain area. Follicles are closely intertwined with
the skin and body and respond to internal physiological changes. Hirsutism, or hypertrichosis, can also affect cycling times and hair growth
patterns. This should be identified when taking the medical history so that thepatient can be counseled to have realistic expectations.
These patients often require more treatments than average and have less predictable response to treatments than patients without
hirsutism or hypertrichosis. Since there is gradual and cumulative reduction with each treatment session, the hair density
(or number of follicles that are growing hair) should decrease. The subjective assessment of how much reduction actually takes place is
approximate at best and often inaccurate by many patients and clinicians alike. The actual percentage of reduction can only be calculated
by performing hair density counts. The simplest way to counsel a patient to have realistic expectations is: over several treatment sessions
there will be less hair growth. This is a gradual and cumulative reduction. When hair does grow back between each of the treatments,
there will be less of it, and it will be finer, lighter and slower growing.
