STUDYING THE EFFECTS OF LOW-LEVEL LASER THERAPY ON HAIR GROWTH AND SCALP CONDITIONS

Abstract

Background: Androgenetic alopecia is the most frequent kind of hair loss that affects both men and women. After puberty, androgenetic alopecia can appear at any age. As the age of the afflicted people increases, there is a progressive escalation in the severity of androgenetic alopecia. 

Aim: the goal of therapeutic treatment is to either fully halt the process or stop it from progressing too quickly.

Methods: A verified diagnosis of androgenetic alopecia based on the Norwood-Hamilton classification for men and the Ludwig classification for women. All of the individuals were instructed to keep their hair colour and style the same and to abstain from using any hair products that may impact their scalps or hair development during the research period. Sebum secretion from the scalp, erythema index, Global Aesthetic Improvement Scale score, and photrichogram for thickness and density of hair were measured at baseline, 12 weeks, and 24 weeks in all research participants. 

Results: The study's findings demonstrated that, 24 weeks after treatment, there was a statistically significant increase in hair density and thickness (p=0.01 and <0.1, respectively). Additionally, sebum excretion from the vertex region was significantly reduced (p<0.1). Improvement in the overall look of the scalp was seen in 73.47% (n=72) of the 98 research participants.

Conclusions: This study shows that using low-level laser treatment equipment that resembles a helmet can assist to improve the overall look of hair by increasing its density and thickness. Because it reduces sebum secretion, it can also help with scalp conditions.
