Laser Science AB's Comment (Manufacturer)

Client/patients undergoing treatment with Invision Laser Light Hair Therapy may experience a sensation of heat, accompanied by a tingling feeling from the scalp to the neck during treatment.

Invision Laser Light Hair Therapy has no thermal component, and the warm feeling can be attributed to stimulation of microcirculation of blood supply.

Furthermore, initially an oilier scalp is often noticed. The scalp usually normalizes after two to four treatments. Conversely, a scalp that was oily before treatment will normalize in the same way. This condition has not been fully explained, but is believed to be the result of the normalization of the sebum (lipid) secretion from the sebaceous gland during treatment, after inactive hair follicles have been stimulated, the sebum (5a reductase) is thought to play a role in hair loss and regrowth. The described reaction to treatment is a natural reaction, which indicates that the therapy is working.
