Liquid Hair

Supporting a stronger hair appearance, the System Professional Extra Liquid Hair visibly reinforces the fibre for up to five washes. Ultra-light, the liquid formula is ideal for all hair types, delivering long-lasting moisture that plumps and thickens the feel of fine, fragile strands. Thermally activated with your hairdryer to ensure optimal ingredient efficacy, the treatment rinses out after heat exposure to leave hair noticeably smooth, while niacinamide and amino acids nourish and protect from root to tip.
