Is it ok to tie your hair up while having nits?

No. Tying your hair up can make it more difficult to remove nits and lice. Nits are the eggs of lice, and they are very small and difficult to see. When hair is tied up, it is harder to get a good look at the scalp and find nits. Additionally, tying hair up can create a warm, moist environment that is ideal for lice to thrive. It can also make it harder to apply lice treatment products to the scalp. For these reasons, it is best to keep hair down and loose while treating lice and nits.
