Our k-tips are from Southern temples of India. We offer 100% raw textures & steam treated textures. This installation should be performed by a trained licensed cosmetologist, and should take around 4-6+ hours to complete. We recommend having your stylist do a consultation prior to installation to ensure that k-tips are right for your hair type. During your installation, strands of hair are cocooned by the keratin bonds using a low heat or frequency tool. Our k-tips are pre-bonded and ready to use. Our k-tips are durable, and can last 3 to 5 months per install with proper maintenance. There is typically no regular salon maintenance necessary throughout your wear. K-tips are not reusable. You should need 100-150 grams of hair for a natural look, and 200+ grams for a voluminous look. Confirm the preferred quantity with your stylist. Our k-tips come in 50 gram bundles.
