How does laser therapy work?
Case 1 – Laser therapy for hair removal
Laser hair therapy uses radiation that helps to produce the laser beam. This laser beam is of non-ionising radiation, which kills the hair follicles to stop hair growth. It prevents the development of new hair and thus helps to get rid of hair for a long time or permanently.
Case 2 – Laser therapy for hair regrowth
How does laser therapy help in the hair regrowth process?
You might have heard about laser caps, laser combs, brushes etc., to stop hair loss. The theory is that when hair follicles absorb laser light at a certain level, it stimulates hair to grow. But there’s not enough evidence that any of these devices restore hair or prevent balding. (Source: Webmd – Hair loss treatment)

Does laser therapy cause cancer?
Laser therapy uses radiation in the form of a laser beam. This laser beam is non-ionising which is very different from Ultraviolet rays that tends to cause cancer. It is one of the reasons that make people believe laser therapy causes cancer.
It is true that ionising radiation like x-rays can sometimes cause cancer but as said the laser therapy uses non-ionising, which is different from all.
The ionising radiation tends to damage the DNA cells that can cause cancer but as said the laser therapy uses non-ionising radiation. The minimal amount of light will reach the follicles, and not penetrate deep inside the body.

- People who get exposed to the sun soon after the procedure might face blisters. So, the dermatologist’s advice is to stay away from the sunlight after the process.
- There are no studies that prove pregnant ladies should avoid laser therapy but still one must avoid it for safety reasons.

1. Which type of radiation is used for laser hair therapy?
Laser therapy uses non-ionising radiation as the source of light, not ultraviolet rays, X -rays, or nuclear radiation. These concentrated light sources will not go deeper into the skin and thus it is safe.
2. Who must be cautious while undergoing laser hair therapy?
Researchers have found that laser therapy can change a typical mole. So, people who have a history of skin cancer or atypical moles must be cautious if they find any rare side effects after the process. But none of the studies or results proves that laser therapy will indeed cause cancer.
