K-tip and weft extensions are an investment — and how you care for them between appointments decides whether they last three months or six. This is the method-specific aftercare routine we teach every extension client at Iron + Ivy in Queenstown: what keratin bonds need, what weft rows need, and where the two differ.
Caring for K-Tip (Keratin Bond) Extensions
K-tips attach with small keratin bonds fused near the root, so the golden rule is simple: protect the bond. Keep conditioner, masks, and oils from mid-length to ends only — product on the bonds softens the keratin over time and shortens the life of your install. Wash with a sulphate-free shampoo, massaging the scalp gently between rows rather than scrubbing over them.
When drying, rough-dry the root area first on medium heat so the bonds never sit wet against your scalp, then finish the lengths as normal. Direct, concentrated heat on the bonds — from a dryer nozzle held too close or a straightener run to the root — is the fastest way to compromise them.
Caring for Weft Extensions
Weft rows need airflow. The most common weft problem we see in the salon isn’t damage — it’s a row that stayed damp overnight and started to smell or matt at the seam. After washing, dry the row itself thoroughly, lifting it away from the head to get air underneath. Never sleep on a wet weft.
Brush your rows morning and night with a loop or soft-bristle brush, holding the row at the base so you’re not tugging on the attachment points. Work from the ends up, and pay extra attention where your natural hair meets the top of the row — that junction is where tangles start.
The Rules Both Methods Share
Sleep with your hair in a loose braid, ideally on a silk or satin pillowcase. Detangle before every wash, never while soaking wet. Rinse thoroughly after swimming — Queenstown lake water is kind, but chlorine and salt water are not. And always use heat protection before hot tools on the lengths.
Your Maintenance Schedule
Weft rows need a move-up roughly every 6–8 weeks as your natural hair grows. K-tips run longer — most clients come in around the 10–12 week mark for a check, with a full removal and re-install at 3–4 months depending on hair growth and care. Booking your next maintenance before you leave the salon is the single best habit for extension longevity.

Frequently Asked Questions
Can I use my normal shampoo on K-tip or weft extensions?
Only if it’s sulphate-free. Sulphates dry out extension hair quickly because it doesn’t receive your scalp’s natural oils. Your Iron + Ivy stylist can recommend the right wash routine at your appointment.
How often should I wash my extensions?
Two to three times a week is ideal for most clients. Over-washing dries the extension hair; under-washing lets oil build up around bonds and rows.
Can I tie my extensions up?
Yes — K-tips especially move well in ponytails and updos because the bonds are small and placed for movement. Keep ties loose overnight.
What happens if I skip a maintenance appointment?
Grown-out bonds and rows twist, tangle, and pull on your natural hair. Staying on schedule protects both your extensions and the hair underneath.
