What is HAIRestart™?
Fotona SMOOTH® operates at the optimal infrared Er:YAG laser wavelength (2.94 μm) that coincides with the maximal absorption in the skin. The unique patented feature of Fotona SMOOTH® is the ability to act in a non-ablative manner, producing precisely engineered mild thermal pulses. This ensures that the laser light is delivered to the tissue gently and efficiently, heating the scalp in a safe and controlled pulsed way.
Proposed mechanism of action
Laser thermal pulsing of the scalp activates paracrine signaling pathways inside the skin, resulting with the
production of growth factors and new extracellular matrix proteins, which promote tissue regeneration.
Activation of Wnt/Beta-Catenin signalling pathway triggers dermal papilla (DP) cells to form hair follicles from epithelial cells.
• Improved vascularisation of hair follicles
• Activation of keratinocytes, fibroblasts and dermal papilla cells, resulting in improved follicle activity and the promotion of new follicle growth
• Prevention of further hair loss
• Increase in hair density and thickness
