How many sessions to complete laser hair removal ?

How many laser hair removal sessions are needed for skin laser hair removal ? OR how many sessions for laser hair removal ? , it depends on following below factors :

1 - Area Being Treated :

Skin laser hair removal can be done on every body part but ' laser hair removal how many sessions' ,,,  is linked specifically to body area being treated , because each body part has different hair density and size . As we know every body part differs in hair density  and size with another body part , therefore each body part being treated will take different laser hair removal number of sessions to complete the laser hair removal treatment. Hair density and area being treated size also varies person to person , so laser hair removal sessions required will be different person to person also. 

For example, generally legs and backs take more sessions to complete laser hair removal therapy , because of bigger size of area and greater hair density . Legs and backs treatment takes two hours and a half  almost ,while an upper lip and ears tops take 8-10 minutes  . The under arms and front of neck treatment can take up to 20 minutes.

2 - Hair Density / Thickness

How many laser hair removal sessions ? It also depends on hair density . As we know hair density varies on different body parts , person to person and also hair density may be greater or lesser if a person belongs to any Asian or European country respectively. More coarse areas will take greater number of treatments and less coarse areas will take lesser treatments and time .

3 - Hair Color

How many sessions of laser hair removal is needed ? It also depends on hair color . Laser hair removal is recommended mainly for dark hair and light skin therefore , the treatment will take lesser time on these type of hair and skin . Advance laser technology can produce better results for those with red or blonde hair , dark hair and dark skin pigments too but it may take longer time than other hair color types .

Laser hair removal technology works by targeting dark pigment . Therefore , it works best for pale / dark skin .The lighter the skin and the darker and more hairy , the better are the results .

Laser hair removal will not work on white , grey , light red or light blond hair follicles and also people suffering from PCOS ( Polycystic Ovarian Syndrome ) may experience poor results unless they receive proper medical treatment along with laser treatment.

Generally Laser hair removal works better with a high contrast in skin and hair color i.e darker hair,lighter skin.The reason is that darker skin absorbs less laser light so remains less effective against required results.
