Low-Level Laser Therapy

It is pretty common for most people to lose about 100 strands of hair from their scalp every day. For the vast majority of people, the fallen hair would grow back. However, for some, that’s not the case. This could be attributed to a variety of factors like stress, genetics, health conditions, etc. This takes a toll on their confidence and general mental health. 


A really effective and non-surgical way to reverse this situation is Low-Level Laser Therapy.`

What is Low-Level Laser Therapy?

Low-Level Laser Therapy or LLLT is an effective non-surgical hair restoration treatment. It also goes by the name cold laser therapy and red light therapy. In LLLT, we use lasers to stimulate cell growth and supercharge hair follicles by a process called photobiostimulation. The goal of the LLLT procedure is simple – to improve the appearance and volume of the hair by combating hair loss. 


LLLT is used in various hair disorders like telogen effluvium and androgenetic alopecia. In this, the hair starts shrinking and becomes dormant, which finally ends in a complete stoppage of hair growth. 


Laser light at a particular wavelength has the ability to penetrate the scalp. The light photon is generally absorbed by the hair follicles, which in turn promotes growth. The photons stimulate the stem cells that are responsible for the regeneration of hair follicles. 


The treatment also boosts the production of ATP(Adenosine Triphosphate) and improves the metabolic process of cells for quicker hair growth. The photons increase the blood flow in the target region of the scalp and improve the delivery of nutrients and oxygen to the hair follicles. This, in turn, promotes thicker and longer hair.

Who needs Low-Level Laser Therapy?

This treatment is ideal for people who are at the initial stages of hair fall or experiencing partial hair loss. A word of caution – there won’t be any growth in the areas where the scalp was bald for many years. This is primarily because LLLT only promotes hair growth by stimulating the hair follicles. In a totally bald area of the scalp, the hair follicles are usually dead; hence LLLT has no effect on those areas. 


LLLT is also used to treat other forms of hair loss like the one caused due to chemotherapy or menopause, or pregnancy. LLLT has also been shown to be more beneficial to patients who get this treatment after their PRP or hair transplant treatment. LLLT is ideal if adopted in conjunction with other hair procedures.

Is Low-Level Laser Therapy painful?

The LLLT procedure is a non-invasive procedure. Patients won’t feel any pain or discomfort during and after the treatment as only laser beams are concentrated on the area that is to be treated. The laser wavelength that is used in the treatment is almost similar to the one that is used in spas and salons. Hence, there isn’t much pain that one will experience.

What to expect after Low-Level Laser Therapy?

There is no downtime or recovery time after the LLLT. Most patients go back to their regular life after it. Research has found out that 85% of patients undergoing the LLLT have experienced a slow down or complete stoppage of hair fall. Also, in 55% of cases, patients saw hair growth in areas where there was hair thinning previously.  


One can start seeing results in just months after the procedure. The results tend to improve over time. Remember – LLLT is a continuous treatment, and you need to attend multiple sessions. If the treatment is interrupted in between, there is a possibility that hair loss will resume, and in a few months, your hair will go back to its initial stage.
