Is Low-Level Laser Therapy Effective for Hair Loss Treatment?

Low-Level Laser Therapy, often referred to as LLLT, has seen increasing popularity in the form of helmet-like devices designed for scalp exposure. In today's blog post, we delve into whether LLLT can genuinely have a positive impact on the scalp and hair.

Recent Research on LLLT

A recent study has been published in the Indian Journal of Dermatology, examining the effects of LLLT. This research observed 50 participants over 24 weeks. What were the results?

Assessing the Impact of Low-Level Laser Therapy on Scalp and Hair Growth

All participants used a helmet-like device emitting light waves of 630-690, 820-880, 910-970 nm for 20 minutes daily over 24 weeks. Hair thickness, density, and scalp sebum levels were evaluated at the beginning, 12 weeks, and 24 weeks.

The results showed that after 24 weeks of treatment, hair density and hair thickness increased significantly (both P < .01, P = 0.013). Sebum secretion in the frontal area of the scalp significantly decreased (P < .01). Among 49 participants, 73.47% reported an overall improvement in their scalp's appearance (n = 36).

Both hair de nsity and diameter showed significant improvements.
