The average number of sessions needed for laser hair removal...

You should not think of "a number of sessions needed" to reduce hair growth.  More sessions are needed in the beginning (around 3-4 for the body and 5 for the face).  After that, the sessions should be spaced out significantly in order to touch up areas from time to time.  It does depend on the person and type of skin so a darker skinned patient may need more sessions.  Also, if a patient has excessive hair growth due to a hormonal imbalance, more sessions may be needed.  Consult your doctor so he or she can examine the areas that you would like treated for your best options.

Number of Sessions Needed for Laser Hair Removal

With multiple Laser hair removal treatments, significant long-term reduction can be achieved. In general, two or more treatments are required at each site.  The laser is only effective when the hair follicle is in its active growth phase.  Repeat sessions will be necessary to treat those follicles when they re-enter the growth phase.  Optimal long-term benefits depend on the area you wish to have treated, the hair density, and your hair’s growth cycle.  Darker hair responds best to the laser, while lighter hair is less responsive.

Number of laser treatments to stop hair growth

The quick and common answer to your question is 5-7 treatments with a hair removal laser (i.e. an Alexandrite, diode, or Nd:Yag) are required to render hair follicle incapable of producing new hairs.  No new hair growth is the ideal and attainable end point.   It is important to remember that 5-7 treatments is the average number of treatments required.  This means that some individuals and/or some areas on the same individual may require less or more than the average.  Some areas may respond to fewer treatments than other areas.  In my experience, the legs and forearms respond more quickly than the face, axillae, and bikini area.  Additionally, in the setting of Polycystic Ovarian Syndrome, more than the average number of treatments are often required to stop hair growth.

Average amount of sessions for laser hair removal

Since hair grows in cycles, the number of treatments varies by patient skin type, hair color, and hair coarseness. But it typically takes about 6 to 8 treatments, spaced every 4 to 8 weeks. Additionally, annual touch-ups may be required to keep you completely hair free.
