Previous page Next page When should I choose Venice Botox or Venice Smoothing Keratin? Both products reduce volume, control frizz, and hydrate for straighter, manageable hair. Key difference: Venice Hair Botox lasts up to 3 months, while Venice Smoothing Keratin offers results for up to 6 months. Is it safe for color-treated hair? Yes, both Venice Keratin and Venice Botox are suitable for color-treated hair. However, they may cause a slight color change. For best results, apply the keratin treatment first and wait 3 to 5 days before coloring your hair. Does it cause hair breakage or fallout? No, these products help reduce breakage by strengthening and hydrating hair strands. However, we highly recommend performing a strand test before full application. Always follow the instructions and avoid applying the product to the scalp. Do I need to use an anti-residue (clarifying) shampoo before applying? It’s not required since both products are one-step applications. However, using an anti-residue shampoo beforehand can improve results by removing buildup, allowing the product to penetrate more effectively. Does this product contain formaldehyde? No, these products are formaldehyde-free. They are carefully formulated to provide gentle yet effective treatment without harmful substances that could damage your hair or irritate your scalp.
