Laser Hair Therapy and How It Helps Hair Loss

Laser hair therapy, also called low-level laser therapy (LLLT) is a relatively new method of hair restoration and preventing further hair loss. The concept is that low-level laser light can stimulate non-productive hair follicles to grow new hair and prevent still-active follicles from losing hair. This is a non-surgical method of regrowing hair and preventing further hair loss. It is considered an alternative to other methods of hair loss prevention and regrowth, including the use of Rogaine and other products.

In healthy adults, hair follicles are typically actively growing hair for a number of years before the hair is shed. The follicle may then enter into a dormant period where it rests before resuming its function and growing more hair. This happens in random follicles at varying intervals, so large amounts of hair loss are not experienced. When increasing numbers of roots lose the hair and fail to resume growing more, bald areas begin to show. Eventually, the follicles die off, which is the cause of permanent hair loss.

Although dead hair follicles cannot be revived, it is believed that many hair follicles are still dormant, which can benefit from the laser hair therapy. Stimulating the hair follicles in those areas with LLLT stimulates the follicles that are in a dormant state, slowing or even halting the process of hair loss and causing hair to regrow in bald areas.
