Laser and Light Therapy Combined With Topical Minoxidil for Alopecia Areata: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

This study reported that while topical minoxidil exhibits hair regrowth in androgenetic alopecia, oral minoxidil 5 mg/day was more effective than topical forms after six months, with low doses also potentially effective for women and other hair loss types.

In this study, researchers evaluated the use of adipocyte-derived stem cell conditioned media combined with fractional laser or microneedling for treating refractory alopecia areata, finding that 64.3% of patients had significant hair regrowth, suggesting this combination may be an effective and safe treatment option.

This review summarizes the pharmacology, mechanisms, and clinical efficacy of topical immunotherapy for alopecia areata but reports no new clinical results.

This review article provides an updated overview of the pharmacology, mechanism of action, clinical efficacy, and adverse events associated with topical minoxidil, a widely used treatment for androgenetic alopecia and other hair loss conditions, while noting that its exact mechanism is still not fully understood.

This study found that 1,540 nm fractional erbium-glass laser treatment combined with topical minoxidil significantly increased hair regrowth in alopecia areata patches compared to minoxidil alone, with response rates of 60% versus 16%, though the long-term effects remain unknown.

This study found that both topical calcipotriol and narrow band ultraviolet B phototherapy improved hair regrowth and vitamin D3 levels in alopecia areata patients.

This study observed that combining nonablative fractional laser treatment with topical minoxidil led to hair regrowth in Chinese alopecia areata patients, noting complete regrowth in some patients and no relapse in the majority at a one-year follow-up, without reported side effects.

This review discusses the use of topical minoxidil for various types of alopecia and reports mixed evidence on its efficacy, with stronger support noted for conditions like eyebrow hypotrichosis and chemotherapy-induced alopecia.

This review assessed evidence on laser therapies for alopecia areata, reporting that the 308-nm excimer laser showed hair regrowth in several studies, while more research is needed for other laser types.

This article reviews current and emerging treatments for alopecia areata, including Janus kinase inhibitors, highlighting variability in clinical outcomes and the lack of sustained remission.

This article reviews the epidemiology, clinical evaluation, and pathogenesis of alopecia areata and highlights recent advancements, but it does not report new clinical findings.

This review noted that alopecia areata is an autoimmune disease impacting hair follicles and offered insights into its complex pathogenesis involving immune responses, while highlighting ongoing research into new treatments such as Janus kinase inhibitors and other immunomodulatory drugs.

This article updates a diagnostic tool (SALT II) for assessing hair loss by adding more precise measurements of scalp surface area, particularly useful for various types of alopecia.

This study found that platelet-rich plasma was more effective for treating alopecia areata than topical 5% minoxidil, leading to earlier hair regrowth and reduction in hair abnormalities.

This study found that non-ablative and/or ablative fractional lasers promoted hair growth in patients with certain uncommon hair disorders, though effectiveness varied among different conditions.

This study found that narrowband UVB phototherapy alone is not very effective for severe alopecia areata, with improved responses noted primarily in patients also receiving corticosteroid injections.

This study suggests that wounding skin in adult mice can trigger new hair follicle formation, indicating mammalian skin may have greater regenerative capacity than previously thought.

These guidelines for alopecia areata management, prepared by the British Association of Dermatologists, provide evidence-based treatment recommendations and insights into the condition's epidemiology, diagnosis, and investigation.

This study found that 1% minoxidil topical solution led to terminal hair regrowth in some patients with alopecia areata, though it was only cosmetically acceptable in less than half of those cases.
