Does long hair moving between the forehead and the place of prostration affect the validity of the prayer, and what is the ruling on praying in this situation?

According to the majority of jurists (Hanafi, Maliki, and Hanbali schools), prostrating on one's hair, sleeve, turban tail, or turban coil does not invalidate the prayer. However, prostrating on these items is not permissible in the Shafi'i school and is considered among the things that invalidate prayer. It is advisable to avoid this to steer clear of scholarly disagreement.
