Objectives: The aim was to evaluate the effectiveness and safety of non-ablative Er:YAG laser, new stmooth protocol used in clinical practice, alone or in combination with other treatment modalities, in patients with both early and advanced stages of AGA. Introduction: Laser hair growth stimulation is an effective method of treating hair loss disorders. This innovative solution is focused on stimulation dormant hair follicles to promote hair growth. With New Laser Smooth modality enables treatments that ensure highly controlled delivery of energy and provide the best comfort for the patient. Practitioners can effectively and safely deliver unique temporal and spatial temperature profiles to the scalp, resulting in increased tissue regeneration and the promotion of new follicle growth. Materials / method: We used this new protocol in 90 patients The method of action lies in the smooth pulses that gently deliver laser light to the tissue, triggering the scalp in a safe and controlled way. Laser Smooth operates at the optimal infrared Er:YAG laser wavelength (2.94 μm) that coincides with the maximal absorption in the skin. Efficacy was assessed with clinical assessment of AGA grade (Ludwig scale for female / Norwood-Hamilton scale for male) Results: We had demostrated high efficacy and an absence of adverse effects. Significant improvement of hair growth along with increased hair density, and a stabilization of hair loss were reported, regardless of AGA (androgenetic alopecia) grade, patient age or AGA duration. Conclusion: Our results suggest that the non-ablative Er:YAG laser new smooth mode as a monotherapy is an efficient and safe treatment for AGA—with a high satisfaction rate among patients regardless of patient age, AGA duration, or AGA stage.
