How Does Laser Phototherapy Help Hair Loss?
The Science behind LPT
There are hundreds of studies that can be read online regarding the effects of cold Laser Phototherapy (LPT). Ironically it was the use of lasers for hair removal which eventually led to their use in hair growth.
It was noted that some patients treated for hair removal experienced hair growth in the surrounding treatment area. This was due to low energy light being reflected off the treatment region. This is known as paradoxical hypertrichosis.
Studies have shown that LPT has a therapeutic effect on targeted human cells positively altering metabolism and increasing:
- ATP production
- Protein synthesis that boosts cell replication and migration
- Growth factors and inflammatory mediators
- Tissue oxygenation
- Nitric oxide (NO) release, which augments vasodilation
The properties above are highly beneficial in the treatment of hair loss and in overall scalp health. By treating the scalp with laser Laser Phototherapy many hair loss sufferers experience:
- New hair growth
- Reduction in hair loss
- Increased hair diameter
- An improvement in overall hair quality
LPT provides benefits to patients who undergo hair transplant surgery. This improvement is due to reduced scalp inflammation and increased healing speed of damaged tissues due to the treatment process. Not only does the the use of LPT improve the post transplant healing time, many users report less shock loss (hairs temporary lost adjacent to the recipient site) and a faster growth of newly transplanted donor hair follicles.
