    Caring for tape-in hair extensions is crucial to maintain their quality and prolong their lifespan. Here are some essential tips to help you care for your tape-in hair extensions:

    1. Avoid Conditioner on Tape Bonds: Apply conditioner to the mid-lengths and ends of your natural hair, but avoid the tape bonds to prevent them from slipping.

    2. Keep Away from Heat: Minimize heat styling as much as possible. When using heat tools, apply a heat protectant spray, and use a lower heat setting.

    3. Sleeping: Tie your hair in a loose braid or ponytail to prevent tangling during sleep. Consider using a silk or satin pillowcase to reduce friction.

    4. Avoid Oily Products: Keep oily or greasy products away from the tape bonds, as they can weaken the adhesive.

    5. Avoid Swimming in Saltwater or Chlorinated Pools: Saltwater and chlorine can damage the extensions and adhesive. If you must swim, wear a swim cap or keep your hair out of the water.

    6. Regular Maintenance: Visit your stylist every 6-8 weeks for a maintenance appointment. They can reapply or adjust the extensions as needed.

    7. Avoid Tugging or Pulling: Be gentle when styling and tying your hair. Avoid tight hairstyles that could pull on the extensions.

    8. Don't DIY Removal: Never attempt to remove tape-in extensions by yourself. Always seek professional help to avoid damaging your natural hair.
      • Use sulfate-free shampoo and conditioner.
      • Curl, style, dye to darker color.
      • Wash, dry, brush gently, always from root to end.
      • Use heat protection.
      • Sleep with a silk pillow.

      FINAL TIP: Do not attach the Keratin bond extensions too close to your face. If the extensions are too close, they could be visible when you put up your hair in a ponytail or do other updos.
       Can I wear your hair up with K Tip Extensions?

      Yes. If you wear ponytails, messy buns, or up-dos, wear them loosely. Use heat protectant if you can't go without straightening or curling your hair. Use a basic bottom-up brushing technique with the proper extension brush.

      Do K-tip Extensions cause headaches?

      One reason hair extensions can give you a headache is because they could be applied too tight. If this is the case, do not be alarmed. As your hair grows out over the next few days the strain on your natural hair will loosen and should ease the tension that is pulling against your scalp.

      Are K Tip Hair Extensions comfortable?

      k-Tip extensions blend seamlessly with your natural hair, providing a discreet and realistic appearance. The individual strands allow for more movement and flexibility, making them comfortable to wear.
