Let's return to the topic of "kes" and how to dispose of fallen kes.
With regard to the disposal of a dead body, the Sikh Rehat Maryada says this, in Section 4, Chapter 11, Article 19
c. However young the deceased may be, the body should be cremated. However, where arrangements for cremation cannot be made, there should be no qualm about the body being immersed in flowing water or disposed of in any other manner.
Rules about the disposal of dead bodies are liberal. So, why not also for hair? Therefore, I would surmise that there should be "no qualm" about the disposal of kes be it cremation, in bodies of flowing water or " in any other manner."
