This study reviewed and analyzed existing research on laser therapy for alopecia, suggesting both low-level and high-level lasers may serve as effective treatment alternatives.

This commentary highlights the importance of additional sun protection for individuals with alopecia, noting that common headwear like baseball caps may provide insufficient photoprotection for the scalp.

This review discusses cases and research on paradoxical hair growth after laser hair removal and explores laser and light therapies for treating alopecia, but reports no new results.

This study found that low level laser therapy at 655 nm significantly increased hair counts in males with androgenetic alopecia.

This review discusses the application of low-level light therapy for hair loss treatment, particularly androgenetic alopecia, and reports no new clinical results; the authors suggest consideration of light source characteristics and potential pros and cons.

In a 24-week randomized trial, this study found that the RAMACAP laser helmet significantly increased hair density and diameter in androgenetic alopecia patients compared to a sham device, although limitations included a small sample size and potential issues with the control used.

This study reviews the use of lasers and light therapies as treatment options for managing the two most common types of alopecia—androegenetic alopecia and alopecia areata—highlighting that existing FDA-approved drugs like minoxidil and finasteride are partially effective, necessitating additional therapeutic approaches.

Low-level laser therapy may increase hair density in pattern hair loss.

This study found that using a low-level laser comb led to hair regrowth in a mouse model of alopecia areata, while sham-treated mice showed no hair regrowth.

In this observational study, the effectiveness of a diode laser was evaluated for treating pseudofolliculitis barbae at the Laser and Skin Surgery Center of New York, but it reports no new clinical results.

In this case report, the authors linked acute psoriasiform contact dermatitis of the forehead and scalp to a low-laser light cap, identifying DMDE in the fabric as a likely cause.

This study found that Low Power Laser therapy may be an effective complementary treatment for scalp alopecia and crural ulcers, showing quicker and potentially better results than conventional treatments.

Lasers might help regrow hair in people with hair loss due to genetics.

This study found that low-level laser therapy significantly improved hair count and reduced hair loss in patients with alopecia areata of the scalp.

This systematic review suggests that laser treatments, especially low-level laser therapy and excimer lasers, may be effective for hair regrowth, though further large-scale studies are needed for validation.

In this study, the combination of CO2 fractional laser therapy with Bimatoprost 0.03% was found to be more effective in promoting hair regrowth in Alopecia Areata patients than laser therapy alone, with higher response rates and minimal adverse effects reported.

This study observed that pooled analysis of LED caps increased hair density in patients with androgenetic alopecia compared to sham, achieving 28.5 more hairs per cm².

This review discusses clinical studies on low-level laser therapy for various types of hair loss and suggests it may be promising for those unresponsive to conventional treatments, but reports no new clinical results.

This article discusses hairline design in hair restoration surgery and reports no new research data.

This review of low-level laser therapy for patterned hair loss found that red-spectrum light may be effective for hair growth, but larger case-controlled studies are needed to further support this conclusion.

In this real-world study, low-level laser helmet therapy for androgenetic alopecia showed that male patients with specific scalp conditions may have better results after more than 180 uses or a year of treatment.

This study revealed that photobiomodulation significantly improved hair density in androgenetic alopecia patients, with laser treatments being more effective than combined laser/LED treatments, while device style did not significantly affect outcomes.

This review discusses the effectiveness of low-level laser therapy for androgenetic alopecia, finding significant increases in hair density and growth for individuals treated with this method.

This study found no improvement in male-pattern hair loss after six months of using laser hair-comb therapy in two men.

This literature review reported that fractional lasers, like the 1550-nm nonablative erbium-glass laser, may enhance hair regrowth by stimulating a wound healing process, but more randomized controlled trials are needed to confirm their effectiveness and optimize treatment parameters.

This review suggests that fractional CO2 laser treatment may be a promising option for treating alopecia areata with a good safety profile.

This study found that cross beam laser is a reliable tool for assessing scalp laxity in hair restoration surgery, with results comparable to the Mayer elasticity scale.

This study found that combining fractional CO2 laser treatment with platelet-rich plasma led to a statistically significant improvement in hair regrowth for male androgenetic alopecia, compared to using the laser treatment alone.

This study found that pulsed infrared diode laser therapy (904 nm) was effective in promoting hair regrowth in 94% of patients with resistant patches of alopecia areata.
