Glossary Laser Technology

use of focused light beams for various precise applications

Laser Technology, also known as Laser Science or Laser Engineering, involves the use of focused light beams to perform various tasks. In the context of hair and alopecia, laser technology is often used in low-level laser therapy (LLLT) to stimulate hair growth by improving blood flow to hair follicles and encouraging cellular activity. This non-invasive treatment can be beneficial for individuals experiencing hair thinning or loss.
