By increasing the diameter of the hair fiber from within, this conditioner delivers volume and fullness to fine, thin hair. The organic Bamboo extract contains natural Silica, which is vital to creating volume in hair. By delivering this Silica deep into the cortex and allowing it to bond to the hair's cortical wall, it boosts rigidity and volume. Please be aware ingredients are subject to change periodically. It is recommended you check the product packaging prior to use for a complete ingredient list.
