I am doing laser hair removal - DIODE - for my neck and beard. 7 sessions passed till now I can see a good improvement but I still have a LOT of hair! Why am I not getting good results?
Laser hair removal is the process of removing unwanted hair by means of exposure to pulses of laser light that destroy the hair follicle.
Lasers can cause localized damage by selectively heating dark target matter, melanin, in the area that causes hair growth, the follicle, while not heating the rest of the skin. Light is absorbed by dark objects, so laser energy can be absorbed by dark material in the skin, but with much more speed and intensity.
Hair grows in several phases (anagen, telogen, catagen) and a laser can only affect the currently active growing hair follicles (early anagen). Hence, several sessions are needed to kill hair in all phases of growth.
Multiple treatments depending on the type of hair and skin color have been shown to provide long-term reduction of hair. Most patients need a minimum of seven treatments. Current parameters differ from device to device but manufacturers and clinicians generally recommend waiting from three to eight weeks between sessions, depending on the area being treated. The number of sessions depends on various parameters, including the area of the body being treated, skin color, coarseness of hair, reason for hirsutism, and sex. Coarse dark hair on light skin is easiest to treat.
Certain areas (notably men's faces) may require considerably more treatments to achieve desired results.
So it depends on several factors and hair growth generations and since you are seeing improvement that is fine and continue ,you only need more sessions ,every one is unique and has different need of sessions.
