Quick answer: At Sølvi Salon in Boise, hand-tied and Genius weft extensions typically last 6 to 12 months with move-ups every 6 to 8 weeks. K-tip extensions last 4 to 6 months. Lifespan depends on three things: the quality of the hair, the at-home routine, and staying on the move-up schedule. Guests who follow the care plan often get 12 to 18 months out of one set.
Extensions are an investment. The most-asked question we get at the consultation is "how long will they actually last?" Here is the honest timeline from a Boise stylist who installs and reapplies them every week.
Hand-Tied and Genius Weft Lifespan
The hair itself lasts 6 to 12 months. Some guests get 18 months out of one set if they are gentle on it. Three things determine where you land on that range:
- Hair quality at install. Cheap hair has been chemically stripped to look uniform. It will tangle and shed within weeks no matter how careful you are. We source from professional companies that sell cuticle-aligned hair, which lasts dramatically longer.
- At-home routine. Sulfate-free shampoo, daily leave-in conditioner, a loop brush, and a silk pillowcase or scrunchie at night will add months to the life of your extensions. We hand every guest a care plan after install.
- Move-up cadence. Wefts need to be moved up every 6 to 8 weeks. If you stretch that to 10 or 12 weeks, the bonds shift, the rows get loose, and damage happens. Skipping move-ups is the fastest way to ruin a beautiful install.
K-Tip Lifespan
K-tips wear differently. The keratin bonds soften slightly over time and need to be removed and replaced every 4 to 6 months. The hair itself can sometimes be reused for a second round, depending on condition.
Because each K-tip is bonded individually, you do not need a move-up every 6 weeks like wefts. You just go straight from install to removal and reinstall on a 4 to 6 month cycle.
The 5-Year Math
Most extension clients ask us to map out the full cost over a few years. Here is what that looks like at Sølvi for a typical Genius weft install:
- Year 1: One full install ($1200-$2000) plus 7 move-ups at $300 each ($2100)
- Year 2: One refresh of hair ($800-$1200) plus 7 move-ups
- Year 3: Possible second refresh, or new hair install
Most of our long-term extension clients spend $200 to $400 per month averaged out, which is comparable to a regular color schedule plus some retail. It is a real investment, and we are upfront about that.
How to Get the Longest Life Out of Your Set
- Use sulfate-free shampoo. Davines OI, NouNou, or Heart of Glass are what we send most guests home with.
- Brush with a loop brush. From ends to root, gently, in sections. Never brush wet extensions without leave-in conditioner.
- Heat protect every time. Extensions hold less moisture than your natural hair, so heat damage shows faster.
- Sleep with it braided or in a silk scrunchie. Friction is the enemy.
- Stay on your move-up schedule. If you cannot make a move-up, call us. We will figure out a Mini Move-Up to bridge.
When It Is Time to Replace the Hair
You will know. The ends start to feel rough no matter how much conditioning you do. Tangling becomes constant. The color fades past what gloss treatments can fix. We will also flag it at your move-up if we see it before you do. Replacing the hair is part of the long-term plan, not a failure of the install.
Frequently Asked Questions
How long do hand-tied extensions last?
The hair itself lasts 6 to 12 months with proper at-home care and move-ups every 6 to 8 weeks. Some guests get 18 months out of one set if they are gentle on it. The install needs to be moved up regularly to keep it secure.
What makes extensions wear out faster?
Heat without protection, chlorine and saltwater, sleeping on wet extensions, brushing too aggressively, and skipping move-ups are the top five. We send every guest home with a specific care routine after install.
When do I know it is time to replace the hair?
When the ends start to feel rough no matter how much conditioning you do, when tangling becomes constant, or when the color has faded past what gloss treatments can fix. Most guests can tell. We will also flag it at your move-up if we see it before you do.
Can I extend the life of my extensions?
Yes. Use a leave-in conditioner daily, avoid sulfates, brush with a loop brush from ends to root, sleep with hair braided or in a silk scrunchie, and stay on your move-up schedule. Guests who follow this routine often get 12 to 18 months out of one set.
How long do K-tip extensions last?
K-tips typically last 4 to 6 months before needing to be removed and reinstalled. The hair itself can sometimes be reused, but the bonds need to be replaced each cycle.
Do extensions damage hair growth?
No, when installed correctly. The myth that extensions slow hair growth comes from cases of bad installs causing breakage at the root. A properly installed weft with the right tension lets your natural hair grow underneath without interference.
