TLDR Low-level laser therapy effectively improves hair growth in androgenetic alopecia with minimal side effects.

The network meta-analysis evaluated the efficacy of low-level laser-based treatments for androgenetic alopecia, analyzing data from 15 studies involving a total of 1,200 participants. The results indicated that low-level laser therapy (LLLT) significantly improved hair density and thickness compared to placebo treatments. The analysis also found that LLLT was more effective than some pharmacological treatments, with minimal side effects reported. The study concluded that LLLT is a promising non-invasive treatment option for individuals with androgenetic alopecia, offering a safe and effective alternative to traditional therapies.

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
