Tape In Extensions
If you’re looking for a quick, comfortable, and natural way to transform your hair, tape-in extensions are one of the most popular methods at Studio W Salon. Tape-ins are applied without beads or clips—your natural hair is gently sandwiched between ultra-thin wefts and secured with a medical-grade adhesive strip. The result? Extensions that are lightweight, flexible, and virtually undetectable.
Tape-in extensions are especially ideal for clients with fragile or fine hair, since they place minimal stress on your natural strands. They’re also a favorite for those who want gorgeous length and volume in a fraction of the time—most full applications take about an hour.

What are Sew In Weft Extensions?
«Weft extensions go by many names, like hand tied wefts, beaded row wefts, and sew in wefts. Our weft extensions are thin and trimmable like genius wefts and are applied with a hidden beaded row method. Application starts with attaching a row of beads using string, then sewing a weft onto each bead. This is where all the training was key. We perfected our technique to keep the tiny beads out of sight and out of mind.
How long can I wear my weft extensions?
«Weft extensions are a long lasting method with proper care at home.

- Reapplication: hair can be removed and reapplied several times
What are tape in extensions?
«No clips or beads, natural hair is sandwiched between wefts and secured with a medical-grade adhesive strip. Wefts are small and flexible, which makes them easy to apply tight to the scalp for a natural look. They are lightweight, no worries if you're concerned about bulkiness, so you can wear a full head without feeling weighed down.
How long do tape ins last?
«No matter which brand of hair we use, tape in extensions are all similar in wear time and the care they need.
- Life span: Hair lasts a total of 5-7 months with proper care.
- Maintenance: Hair is removed and reapplied every 6-8 weeks with fresh tape
- Reapplication: Hair can be removed and reapplied up to 3 times
