Quick answer: Hand-tied wefts work best for medium to thick hair that wants density and length. Genius wefts are the lighter, finer version, ideal for delicate or fine hairlines. K-tips are individual strand bonds, perfect for targeted areas like the face frame or filling a thin spot. At Sølvi Salon in downtown Boise, every method starts with a 30-minute Edit Consultation so the install matches your hair, not a brand quota.
Walk into any extensions consultation and you will hear three names: hand-tied, Genius wefts, and K-tips. They are not the same. They do not last the same. They do not feel the same. And the wrong method on the wrong hair is the fastest way to end up disappointed with what is supposed to be a fun investment.
Here is the honest breakdown from a Boise stylist who installs all three every week.
Hand-Tied Wefts: The Workhorse
Hand-tied wefts are a panel of hair sewn by hand onto a thin track. We attach them to your head by creating a beaded row across the back, then sewing the weft onto that row. They sit flat against your scalp, move naturally, and grow out cleanly when reapplied on schedule.
Best for: Medium to thick hair that wants real density. If you have shoulder-length hair and want it past your bra strap with fullness, this is usually the call.
Maintenance: Move-ups every 6 to 8 weeks. Hair can typically be reused for 6 to 12 months.
Heads up: The seam is slightly thicker than Genius wefts, so on very fine hair it can feel heavier than it needs to.
Genius Wefts: The Fine-Hair Answer
Genius wefts are the same concept as hand-tied, but the seam is machine-finished with a much thinner, flatter top. They lay closer to the scalp, weigh less per row, and disappear better in finer hair.
Best for: Fine to medium hair, anyone with a sensitive scalp, or guests who have tried hand-tied wefts in the past and felt them too heavy.
Maintenance: Same move-up cadence as hand-tied, every 6 to 8 weeks.
Heads up: Slightly less hair per row than traditional hand-tied. We often install one extra row to make up for it.
K-Tips: The Surgical Tool
K-tips are individual strands of hair bonded one-by-one to your natural hair with a small keratin tip. We install them with a heat tool that softens the bond, then crimp it onto a tiny section of your hair. Done. Each strand moves independently, which is why K-tips feel the most like your own hair.
Best for: Targeted placement. Filling in a sparse hairline. Adding density around the face. Blending grown-out layers. Anywhere a weft would not lay right.
Maintenance: Removal and reinstall every 4 to 6 months. The keratin dissolves cleanly with the right product.
Heads up: K-tips cost more per strand than weft hair, but you often need fewer. Pricing is per pack at Sølvi, decided at your consultation.
How We Choose at Sølvi
Most guests come in thinking they want one specific method because they saw it on Instagram. That is fine. We listen. Then we look at your actual hair: density, texture, condition, growth pattern. Sometimes the method they came in for is right. Sometimes a different method is the better call. We will tell you honestly either way.
Every extension service at Sølvi starts with the Edit Consultation. Thirty minutes, $50, applied directly to your install. You leave with a plan, a price, and a clear answer to whether extensions are the right move at all. Sometimes they are not, and we will say so.
Frequently Asked Questions
Which extension method is best for fine hair?
For fine hair, we usually recommend Genius wefts. They are thinner and lighter than traditional hand-tied wefts, so they lay flatter against the scalp and avoid the bulky feeling that thicker wefts can create on a delicate hairline. K-tips also work well for filling in sparse areas around the face.
How long does each extension method last?
Hand-tied and Genius wefts typically last 6 to 12 months with proper maintenance and move-ups every 6 to 8 weeks. K-tips usually last 4 to 6 months before needing to be removed and reinstalled. The hair itself can often be reused on a refresh if it has been cared for.
What is the difference between Hand-Tied and Genius wefts?
Hand-tied wefts are sewn onto a beaded row and sit flat against your head. Genius wefts are an even thinner, lighter version that uses a finer machine-tied seam. Genius wefts feel more weightless and blend better in finer hair. Hand-tied wefts give slightly more density per row, so they are often the call for thicker or coarser hair.
Are K-tip extensions damaging?
Not when installed and removed correctly. K-tips use a small keratin bond that is heat-sealed to your natural hair. The damage risk comes from improper installation, wearing them too long without a reset, or rough removal. At Sølvi, every K-tip is placed with tension control and removed with a keratin dissolver, never pulled out.
Can I swim and work out with extensions?
Yes, but with care. Chlorine and saltwater can dry out the hair and loosen bonds, so we recommend a swim cap when possible and a leave-in spray before getting in the water. For workouts, braid or pony the hair to reduce tangling at the install points. We send every guest home with a specific care plan after install.
How much do hair extensions cost in Boise?
Pricing depends on the method, the amount of hair, the length, and the desired result. Most full installs at Sølvi land between $800 and $2400 including hair, with reapplication appointments every 6 to 8 weeks. We give every guest a transparent quote during their Edit Consultation, so there are no surprises on the day of install.
Can extensions be color-matched to my hair?
Yes. We source from multiple professional hair companies so we can match almost any color, including blondes, balayage, gray blends, and reds. If your color is dimensional, we often custom-blend two or three tones in one install. Color matching happens at your consultation, never on the day of.
Do extensions work for short hair?
Yes, with the right method and a strong consultation. Hand-tied wefts can extend a chin-length cut into shoulder-length or longer, but the install has to be planned around your natural cut so it grows out cleanly. We will tell you honestly if your hair is not ready, and we will sometimes recommend a different service first.
