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.
