ANALYZING THE EFFICACY OF LOW-LEVEL LASER TREATMENT ON SCALP HEALTH AND HAIR DEVELOPMENT

Abstract

Background: In terms of esthetics, regardless of age or gender, the way the scalp and hair look is quite important. For hair loss and scalp issues, however, a range of therapeutic approaches and medications have been recommended; nonetheless, the response to the care is still insufficient.
Aim: The current investigation sought to determine how low-level laser treatment affected scalp health and hair development.
Methods: During a 24-week period, 100 participants were evaluated for this study. A helmet-shaped device that emitted light for 20 minutes a day for 24 weeks at wavelengths of 630–690, 820–880, and 910–970 nm was utilised with all 100 research participants. 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, and 24 weeks in all research participants.
Results: According to study findings, there was a substantial increase in hair density and thickness (p=0.01 and <0.1, respectively) 24 weeks after treatment. 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.
Conclusion: By increasing the density and thickness of the hair, the application of a low-level laser treatment equipment that resembles a helmet can assist to improve the look of the hair overall. It can also reduce sebum secretion, which will benefit the health of the scalp.
