No. Capillus lasers are cool-to-the-touch, meaning your LLLT treatment will be comfortable. In fact, LLLT (low-level laser therapy) is also known as cold laser therapy.
Some users have reported a slight increase in temperature to the treatment area, but this is safe during treatment, and is most likely a result of heat naturally emitting from the covered scalp.
Please don’t hesitate to reach out if you think your device might be experiencing an abnormal increase in temperature.
