Laser-based therapies, including low-level laser therapy (LLLT) and fractional ablative lasers, are effective non-invasive treatments for hair loss conditions like androgenetic alopecia and alopecia areata. A review of 43 studies from 2023 to 2025 shows that LLLT can increase hair density by 15–40%, with optimal wavelengths between 630–680 nm. Fractional CO2 lasers, especially when combined with topical therapies, can improve hair regrowth by 30–75%. Erbium:YAG lasers also show promising results with 40–65% response rates. Combination therapies, such as those with minoxidil or platelet-rich plasma, outperform monotherapies. Common side effects include transient erythema and mild pain. The review highlights the importance of patient selection, appropriate laser parameters, and managing expectations, while suggesting future research focus on standardized protocols and long-term efficacy.
