It's very difficult for you to watch violin bow hair. It's also not something that I would recommend. I think that if you're good just going to take the time to wash your violin bow hair, I think that you should make the effort of taking your bow to a shop and getting it repaired. However, there are some musicians that swear by washing their violin bow hair with warm water and soap. This is something that I tried once before on super low quality of violin bow. And the overall quality of the bow didn't have much to speak for before I washed it. But, there is definitely a significant downgrade in the overall quality by the time I finished washing it. So, I would highly recommend that you don't wash your violin bow hair.
