60# is about shade 10-11 bright blonde. The shade is closest to the shade 60# in traditional BPhair colour chart but is a bit lighter and not as warm.
BPhair Premium Slavic -wave/curly hair is made of naturally curvy hair, non-permanented slavic hair.
The level of the hair's curliness/waviness varies a bit depending on the product because it is made of genuine natural curly hair so the curl may not be exactly the same in every bundle. Like a Finnish natural curl, the wave/curl is slightly rougher than straight hair and requires a straightening iron to be straight and smooth.
Suitable for curly and very wavy hair. For straight as well as gently wavy, we prefer straight extension hair, which also is a bit flexible and gently wavy, especially after washing.
