Liu Hai had an ionic perm, but how did she sweat?

There will be some influence. Try to sweat as little as possible after ion ironing. I don't think you want to do it as long as it affects you a little. So it's best to wait until the end of military training.

If you sweat less, it's nothing. Don't wash your hair for 7 days, you can tie it in 2-3 days, but you can't tie it too tightly, just buckle it. It is best not to edit or disk, which will affect the effect. If you sweat less, there should be no problem. Don't put your hair behind your ears, it will also affect the effect.
