Sandwich method
also called hairtalk or tape on method. This method consists in attaching the hair with the use of silicone bands that fasten subsequent strands of hair to the so-called sandwiches.
To one strand of natural hair, two strands of hair are attached at the bottom and top, thus creating a sandwich. The fixings are almost invisible and imperceptible, they can be lifted and thus refresh the hairstyle as it grows naturally.
Interestingly, the silicone tapes can be reused after removal. This method is recommended for women who have thin and sparse natural hair. The effect lasts for 3 to 4 months. It is worth adding, however, that this method is not suitable for people who like to experiment with hairstyles and wear their hair tied. The silicone bands may then be visible.
