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 hair regrowth.

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.

How Low-level Laser Therapy Grows Hair?

According to its proponents, Chromophores in our scalp absorb low-level laser that increases blood flow and oxygen flow in the area. This causes stimulation at cellular level and causes the hair to become stronger and thicker.

Other clinicians believe that low-level laser works by Photochemical reaction produced by the interaction between laser and hair follicle. This reaction alters the internal processing of the cell and signals it to start growth rather than dying.

Are Claims Made by Low-level Laser Therapy True?

One thing is clear that laser therapy does promote growth of hair follicles. However, there are very limited studies that confirm the extent of growth. In contrast, there are several studies that measured the effects of medical treatments for hair growth, like topical and oral medications (Minoxidil and Finasteride respectively) as well as hair transplant surgery. Even the studies that claim efficacy of laser hair loss treatments agree that the results are time taking and may not be lasting in most cases. The user retains the grown hair as far as he/she continues use of lasers. Furthermore, the results are more noticeable if you use the treatment in conjunction with medication or other hair growth treatment.

Who Can Benefit from Low-level Laser Therapy?

Men and women experiencing either Androgenic Alopecia or genetic pattern baldness are candidates for low level laser therapy. However, laser therapy is not effective in completely bald areas. It can only stimulate existing, weak hair follicles. It is not possible to regrow dead hair follicles. This makes it particularly useful for women suffering from diffused hair thinning. Such women can use this therapy to make their thinning hair strong and thick.

To sum up, laser looks promising. However, in this era of technology, when a hair transplant surgery promises guaranteed, permanent hair regrowth, why one should go for laser hair loss treatment that offers limited benefits.
