Laser therapy helped new hair grow in scarred skin for three patients.

This study tested a novel cryo-carboxy dispensing device for treating androgenetic alopecia in six volunteers and found an unexpectedly rapid and positive response, with significant hair regrowth observed by day 90, prompting early conclusion of the trial.

This study found that using ablative fractional CO₂ laser therapy combined with FUE treatment in patients with post-traumatic eyebrow scars and defects improved follicular survival rates and resulted in well-defined eyebrow shapes.

In this interventional study on female-pattern hair loss, researchers found that fractional CO2 laser therapy alone improved hair growth, as evidenced by increased hair count, thickness, density, and patient satisfaction compared to saline controls. However, the precise mechanisms behind these effects require further investigation.

In this case series, researchers reported an unexpectedly rapid and positive response to a topical, hydrogel-based botanical treatment for androgenetic alopecia in both male and female volunteers, achieving significant improvement in hair loss within 90 days instead of the planned 270 days.
