It will be hard to hide it because they will eventually find out some way or other. But I will say wear hoodies and try not to make it look suspicious like your hiding your hair. If you have a wig or extensions put them on. If they ever find out think of an excuse to make (for example: say that the ends of your hair were very dead and you’ve been planning on cutting it for a little time because it not good for your hair and your hair keeps breaking so that was the reason you cut it)
