What are reactive oxygen species (ROS)?
Reactive oxygen species (ROS) are unstable molecules containing oxygen that can cause cellular damage at high concentrations.
While low levels of ROS play roles in cell signaling, excess ROS contributes to oxidative stress and tissue aging. Red light therapy can modulate ROS levels, promoting balanced cellular environments that favor repair over damage.
Managing ROS levels in scalp tissues helps red light therapy create optimal conditions for hair follicle survival, energy production, and regrowth.
