How can a person STICK her hair to her HEAD???

You may think why i am posting such an ODD and funny question as my post title...
It's because i am very curious and wanna know why "that girl" can really SticK her HaiR to her HEAD!!

I have a few points/statements that help me try to explain about the situation:-

1) She uses Uhu Glu, Elephant Glu or anyother Glu that exist to help her stick it to her head...*Which is quite immpossible, because who will do such a thing?? Only ppl who suffer from some mental case problem ryte?? And to tell the truth... i secretly agree that the particular human being is a mental case person...

2) She is using a invisible hair pin to keep her hair from dropping... Which is also quite IMMPOSSiBLE...Because as far as i know that invisible hair pins haven't been invented yet...

3) She is a Super-Hyperactive person.... What she do all day is keep jumping around or anything else that can make her exercise and sweat... So that she can use her sweat to make her hair STICK there...This MAY BE possible because she is very very THIN like LIDI!!! But in the other hand, IF she is ALWAYS exercising... WHy she don't have muscles one???

4) So far the most possible answer.. Is that the particular human being is a very lazy and dirty person... She doesn't like to wash her hair... She will just leave it and make it all DIRTY & STICKY... so that her hair can STICK to her HEAD!!! Or maybe She DID wash her hair, But she use a Solution With a mixture of Glu & Water!!!

That's all the points n statements i can find... most are just NONsense!!!

Hope u ppl will give some comments n answers to my question!!!^^

And i don't think it is NOT necerssary to not tell who "that girl", the particular human being is a girl from school from 1 Mantap called Marissa, I don't know her full name,But there is only one girl from that class that is called Marissa... So i think it is not a problem to find her...

And Marissa ONE LAST WARNing STOP VIEWING MY BLOG AND DISTURBING MY PRIVACY!!
