From the Research
Low-Level Laser Therapy (LLLT) typically requires 3-6 months of consistent use before showing significant progress for hair regrowth, as supported by the most recent and highest quality study available 1. The treatment works by stimulating cellular metabolism in hair follicles, increasing blood flow to the scalp, and promoting the transition of hair follicles from the resting phase to the growth phase.
- Most patients begin to notice initial improvements such as reduced hair shedding after 1-2 months, with visible hair thickening and regrowth becoming more apparent after 4 months of regular treatment.
- For optimal results, LLLT should be used according to device specifications, which generally involves 2-3 sessions per week, with each session lasting 8-30 minutes depending on the specific device.
- LLLT works best for androgenetic alopecia (pattern hair loss) in its early to moderate stages and may be more effective when combined with other treatments like minoxidil or finasteride.
- Results vary between individuals based on factors such as age, hair loss severity, and underlying causes, as noted in various studies 2, 3, 4, 5.
- It is essential to note that patience and consistency are crucial, as premature discontinuation often leads to disappointing results.
- The safety and efficacy of LLLT for male and female pattern hair loss have been demonstrated in several studies, including a review of the literature that found LLLT to be both safe and effective 1.
