LLLT involves exposing the tissue to low levels of red and near-infrared
light and is known as “low level” because of its use of light at energy
densities that are much lower compared to conventional laser therapy that
is used for ablation, cutting, and thermally coagulating tissue. LLLT also
known as *“cold laser”* because the power density is much lower than those
with conventional lasers.

Frequently asked questions

We now have an FAQ list that we hope will help you answer some of the more common ones.

1. What are the uses of LLLT?

LLLT has been used in all specialties in the medical world ranging
from stroke, neurological and wound healing. LLLT is being increasingly
used in Trichology for stimulation of new hair growth, reducing scalp
inflammation and even reducing hair fall.

3. Is it safe or what are the side effects?

It is one of the easiest to do the procedure as it is non invasive,
painless and is an office time procedure. Improvement is reported in at
least some users after 12 to 26 weeks of use, with reduced hair fall and
noticeable hair growth. It is a very useful adjuvant treatment with other
hair loss treatments that would definitely emphasize about the importance
of regularity, which includes frequent appointments (twice a week) over a
long duration (typically one year). At DSHS, we provide both basic and
advanced form of low-level laser therapy at very reasonable prices in
Whitefield and Marathahalli.

2. How does LLLT help in hair loss?

Low level laser therapy stimulates hair follicles to reenter the
growth phase from dormancy and prolongs the growth phase of the hair. It
helps in preventing premature aging of the follicle. It also increases the
strength of hair by increasing the anchoring filaments in hair.

The hair growth cycle consists of three phases: growth (anagen phase),
resting (telogen phase) and shedding (catagen phase). Hair loss in
androgenetic alopecia depends on a testosterone derivative in the skin,
dihydrotestosterone (DHT). Low-level laser therapy is believed to increase
blood flow in the scalp and stimulate metabolism in catagen or telogen
follicles, resulting in the production of anagen hair. The photons of light
act on cytochrome C oxidase leading to the production of adenosine
triphosphate (ATP)which is converted to cyclic AMP in the follicle cells
releasing energy and stimulating metabolic processes necessary for hair
growth. Release of nitric oxide from cells leads to increased
vascularisation to the scalp distributing nutrients and oxygen to the hair
roots. It even prevents the excessive build-up of Dihydrotestosterone(DHT).
