GK Hair Signature Collection Professional Smoothing Treatment Keratin

This professional keratin system smooths hair, strengthens strands, and reduces frizz for three to five months. A pH‑balanced clarifying pre‑treatment shampoo prepares the cuticle for optimal absorption. The keratin smoothing formula instantly straightens while conditioning from the inside out. A dry‑damage treatment penetrates deep to repair and restore weakened hair. A moisturizing shampoo and conditioner lock in hydration and minimize static for manageable texture. The products are formulated in the United States without alcohol, parabens, or sulfates and are cruelty‑free.
