One spends thousands of rupees on various sitting of laser hair removal treatment so you are bound to feel, will laser hair removal last forever or would I have to shell out my hard-earned money many more times.
Laser Hair Removal
Laser hair removal uses light to target the pigment in individual hairs. The light travels down the shaft of the hair and into the hair follicle. When the laser light gets absorbed, it creates heat. If enough heat is generated down the hair follicle, it will destroy the hair growth centre in the follicle. If the hair growth centre is destroyed, you should not create a new hair. Hair follows a unique growth cycle that involves resting, shedding, and growing periods. Recently removed hair that is in a resting phase may not be able to absorb enough laser light or generate enough heat to destroy the hair growth centre, which is why a series of follow- up treatments are scheduled every 4-6 weeks.
Does Laser Hair Removal Last Forever?
Laser hair removal after several sessions can result in the rate at which the hair grows being severely diminished. But the hair follicles aren’t destroyed. So it is unlikely to permanently remove every single hair follicle because hair growth occurs in multiple phases and can be influenced by hormones or medications. So there’s still a chance that they can repair and begin producing hair again and there will be always a little bit of hair that may come back.
But, most people find that when hair regrows, it is lighter and less noticeable than it was before. This is because the laser may damage the hair follicle even when it fails to destroy it. So, “permanent” laser hair removal is a myth, but after six to eight treatments, you can expect a marked reduction in hair. Any regrowth can be managed with touch-up treatments every six to 12 months. Also, electrolysis is the only FDA approved hair removal method which is permanent.
