Do laser hair extensions really make hair thicker?

Hungarian doctor Endre Mester has been researching whether lasers cause cancer since 1967. He used a low-energy laser on the shaving area of mice and found that the low-energy laser did not cause cancer, laser hair growth ，but could promote hair growth.

Since then, hair experts have continued to conduct clinical research and found that low-energy red light is safe and effective for hormonal alopecia and is suitable for home use.

In terms of safety, low-energy laser hair growth has also been unanimously affirmed by experts. No adverse reactions, no drug side effects, and no treatment risks. This is a safe and effective way to prevent hair loss.

Although laser hair growth is 100% safe and effective, it is not applicable if the hair follicle is completely necrotic and closed. Laser caps for hair loss are based on the presence of hair follicles and are only useful if there is no necrosis. Therefore, once hair loss occurs, you should go to the hair follicle department of a regular hospital for hair follicle examination in time to determine the specific cause of hair loss and treat it as soon as possible.
