Is it True that Laser Hair Removal on the Bikini Area Would Cause Sensation Loss?

Completely false.  Only if someone was severely burned, and even then I doubt sensation would be entirely lost.

Thanks for your inquiry.Hair follicles live in a relatively superficial layer of the skin.  This is what allows laser or pulsed light to destroy the hair follicles. Treatment by these modalities can lead to some superficial inflammation or numbness which is generally short lived.  The nerves that lead to orgasm during sexual intercores are deeper and generally in areas that should not be treated.  Be sure you perform your treatment with an experienced physician to determine if you are a good candidate and avoid risks such as burns and blisters.

There is no scientific basis for any loss of pleasure from doing laser hair removal in the bikini area, nor has my practice ever encountered this problem. 

Laser hair removal in the bikini area should not lead to any long-lasting changing in sensation in the area.

There is no evidence that laser hair removal causes any sensation loss in the bikini area.  You may have some very temporary swelling, redness and superficial numbness immediately following the procedure, but this should resolve in a few days.  There should be no effect on sexual pleasure at all. 

Lasers create a beam of highly concentrated light that penetrates into the skin where it delivers a controlled amount of therapeutic heat. This light energy is absorbed by the pigment located in the hair follicles. The laser pulses for a fraction of a second, just long enough to destroy numerous follicles at a time and leaves the surrounding skin unaffected. Laser hair removal will not cause any of the side effects you are describing. The risks are minimal and may include a bruise, redness, blistering, increased or decreased pigmentation, and swelling in the treated areas. These usually do not last more than a few days.
