Should I wash my hair?

No shampoo, it's full of harsh chemicals

You might use egg yolk mixed with coconut oil n honey.
Make sure to wash it well after using it.

Big take: try your best to not include egg whites even if only 1%

Only the yolk;
the whites will make it smells like shit.

But even if happened, the coconut oil will make it gone anyways and the honey too.
Thanks bro, can you tell me why shampoo is so bad? I just don't explicitly know and I'd like to explain to my mum
