Rebonded

I just came back a couple of days ago, and I went to rebond my hair in Malaysia yesterday! Now my hair is poker straight and itching like hell cos I'm not supposed to wash my hair for 3 days. How am I supposed to do tt?!!! It's so freaking HOT in Singapore! I think I'm gonna give up and wash my hair today and just hope nothing bad happens to my rebonded hair. I read online that it's actually alright to wash after 1 day, and my hair is naturally straight anyway... Hehe.
