What’s the “sandwich” installation method for tape-in hair extensions

What is the Sandwich Method?

As the name suggests, the sandwich method involves “sandwiching” a small section of your natural hair between two tape-in wefts. Just like how a sandwich has a filling between two slices of bread, this method places your own hair in the middle, securely bonding the extensions above and below.

Step-by-Step Installation:

1. Section the Hair
   Start by sectioning your hair horizontally from the bottom up. Clip away the upper layers to expose the area where you’ll apply the extensions.
2. Select a Thin Strand of Natural Hair
   Using a tail comb, take a small, thin slice of your own hair—about 0.5 to 1 cm wide. It should be thin enough for the tape to adhere well, but not too thin to cause damage.
3. Apply the First Tape Weft
   Place the first tape-in extension underneath the strand, sticky side up, and press lightly to hold it in place.
4. Seal with the Second Weft
   Place a second tape-in extension on top, sticky side down, aligning it perfectly with the first weft to “sandwich” your natural hair between them.
5. Press Firmly
   Use your fingers or pliers to press the two tapes together firmly to ensure a strong bond.

Why Choose the Sandwich Method?

• Natural Look: Hair is evenly distributed, so the extensions blend seamlessly.
• Long-Lasting Hold: When properly applied, this method ensures the extensions stay in place for 6–8 weeks.
• Gentle on Hair: No heat or glue is needed, making it a safer method for most hair types.

Pro Tip:

• Avoid washing your hair or using heavy products on the roots for 48 hours after installation to allow the adhesive to fully cure.

• Avoid water or air from being trapped in the bonding area during installation

• If the stickiness is not strong, you can use a heating plate to heat it for 1-2 seconds
