Traditional Keratin Bond Extensions (K-Tips) – Lasts 4–6 Months Keratin bond (K-Tip) extensions are a long-lasting, lightweight solution that works beautifully on natural, relaxed, or color-treated hair. With proper upkeep, these extensions can last 4 to 6 months. The K-Tips are individually wrapped around your natural strands, allowing more of the extension hair to be exposed — providing fuller coverage and a more voluminous look. Perfect for clients seeking a seamless, durable install, this method offers maximum versatility and movement. Installation time is 6 to 8 hours.
