Low-level Laser Therapy for Hair Loss Treatment

When thinking of lasers, the image of sci-fi movies and aliens pops-up in the mind. However, with advancements in technology, lasers have developed a lot and moving out of the sci-fi movies, they have successfully captured the healthcare industry. Medical science is one of the large beneficiaries of laser technology. Lasers have many uses in medical science, ranging from hair growth to hair removal to skin tightening and skin rejuvenation. Let us see how laser can help in hair regrowth treatment.

What Is Laser?

Laser is form of concentrated light of a particular wavelength. In medical science, laser works by targeting specific chromophores (components of human body that absorb light). Three major components in human body that absorb laser light are:

• Melanin (In skin)
• Hemoglobin (In blood)
• Water

When these components absorb laser light, heat is produced. This heat is capable of destroying unwanted cells, removing unwanted water, and resurfacing the skin.

Laser and Hair

When the words laser and hair are used together, the first thing that comes into our mind is laser hair removal. No doubt, laser hair removal is a famous and probably the most commonly sought cosmetic procedure. However, laser is becoming popular in growing hair as well. This laser is known as low-level laser.

What is Low-level Laser Therapy?

While high-level laser is used to heat, cut, and burn tissues to achieve certain medicinal objectives, low-level laser is used to heal the tissues. Unlike high level lasers, low-level laser are not destructive. Doctors have been using low-level laser therapy for a long time to heal wounds.
