3Me Maestri Tourmaline Tube Thermal Brush 4446T, 1pc

The feature of tourmaline is pyroelectricity (it charges electrically if warmed up and then cooled down).
In contact with hair it releases infrared heat and negative ions that cancel the static energy-giving shine to hair; allow water to evaporate more quickly, removing the frizzy effect and sealing the cuticle increasing hair brilliance.
