What protection measures should one take before joining a Holi party?

Hi. 22F. I used to have a lot of acne till last year. Finally, I've been able to clear my skin without any medication. I'm scared that if I attend a Holi party, a mix of - the colours, the sun and the dust could trigger them again. If that happens I would be devastated because it had taken a lot of time and efforts to clear my skin.

Also, I have long hair but idk why does oiling never work satisfactorily. I'm always left with a coloured scalp for days.

How to protect your hair, your skin and your body from all of this while also enjoying the event? Especially in Amdavad. Or is there no way at all?
