Some schools in Scotland have put hair straighteners into changing rooms to try to get more kids to do PE.
The council decided to put them in after some girls said they worried about having bad hair after doing sport.
Would you like them in your changing room? Would it make you more willing to do games at school?
Do you think it's important to look good at school or do you think it's encouraging kids to worry too much about how they look?
Or doesn't it really matter at all?

"I don't think it's a good idea because girls will worry too much about how they look and will end up being vain."
Ciara, 9, Ballynacally, Ireland
"I think that the money should have gone to better use because girls don't have to look good every single day!"
Molly, 11, Dorset, England
"I think children are worrying way too much about their looks. Putting hair straighteners in schools just encourages girls to use them unnecessarily. Everyone looks bad after PE. You're hot and sweaty - it doesn't matter as it happens to everyone."
Alice, 14, Worcester, England
"I think it's quite a bad idea because the money could have been put to better use. Also fights could kick off over the straighteners. It isn't a fashion show, if someone is that worried about their hair then just tie it back that day."
Callan, 12, Northern Ireland
"It's not important to look good in school because it's not fashion show but you do need to look good on occasions."
Zoe, 11, London, England
"I think there would be a long line to get your hair straightened though, and you only get like five minutes to change and it takes me ages to straighten my hair, I have to wake up at 6am to have it perfect."
Lana, 14, USA
"Looking good doesn't make you a better person - if anything it just makes you seem vain. If you put hair straighteners in changing rooms then people will squabble over them. Also they'll be late for their next lessons or won't have as long to do PE."
Bethan, 14, Essex, England
"I don't think it's that important to do your hair ALL the time. I am thankful for the hair I have been given. Also, straightening your hair that many times a day can damage your hair - and what about being eco-friendly and saving money?"
Hannah, 12, Dundee, Scotland
"I think it is a nice idea and I would use them, but there might not be enough for everyone and it might be hard to find time to do it. My friend Jenna takes ages to do her hair!"
Amy, 12, Worcester, England
"You do still need to look after yourself but you don't need to over do it, it's just school."
Bethany, 10, Swindon, England
"I think it's a super bad idea - the girls' hair will be fried to death, especially if they are not using some of that protection spray and they already straightened their hair in the morning! Their hair will be ruined if they keep straightening and it will be even worse than before. If girls keep straightening, it will go even more frizzy and get worse - at least have a hair solution!"
Louise, 12, Macclesfield, England
"I think it's stupid to spend money on straighteners to persuade girls to do PE, when you could spend it on equipment that everyone might find interesting! I'd like it then!
Megan, 12, Derby, England
"Yes, yes, yes... that would be the best!!"
Charlotte, 10, Blackpool, England
"I think it is important! Of course, you don't want nits spreading, but it is a bit mean... curly hair is beautiful and honestly, kids with curly hair will be offended - its not their fault."
Sharon, 13, Cardiff, Wales
"I REALLY doubt I would EVER use them at all - PE shouldn't be about looking good. But I suppose if it persuaded more girls to keep fit, it might be a good idea."
Juno, 11, London, England
"I think that you should not put hair straighteners in the changing rooms, as sport is a very important subject and you have to do it."
Gaby, 12, Hertfordshire, England
"Yes, you do need to make an effort but you don't need to cover your face in foundation and eye make-up!"
Jodie, 13, Lancashire, England
"I think its stupid. People will feel left out if their parents don't let them straighten their hair."
Alisha, 12, Slough, England
"I think it is mad to have hair straighteners in school. It might be good to look your best, but if that's important, girls should straighten their hair in the morning."
Charlotte, 13, Durham, England
"It's fantastic! I would love to have some in my school and most girls (like me!) avoid sports to keep their hair nice."
Fatima, 11, Leicester, England
"You should look presentable when you go to school, but hair straighteners in changing rooms? That's so stupid - and all those girls who use it everyday will have their hair falling out and will wish they never used it."
Suzanne, 14, Herts, England
"It's OK to want to look good and after sweating loads and having to tie your hair up can leave massive kinks. I think all schools should have them!"
Rachel, 13, Chelmsford, England
"It's OK to look good but there's no need to be too fussy at school!!"
Ada, 11, London, England
"I think that they shouldn't have hair straighteners in school because they could have lice or grease on them. Also they'll use a lot of electricity which isn't good for the environment!"
Laura, 12, Northern Ireland
"I think it an ok idea. I don't really bother with my hair after PE but some of the girls in my year do."
Colette, 12, Glasgow, Scotland
"I think it is a good idea because my hair gets really messy in PE and I want it to look nice. So if I straighten it I will look better."
Kelly, 13, Greater Manchester, England
"I don't think it's a big deal. You don't have to look your best all the time, even if there's a boy you want to impress!!!"
Dana, 9, Portsmouth, England
"I don't think you have to look perfect for school because your uniform represents your school not your hair."
Emma, 12, Somerset, England
"I think it's a great idea as my hair is normally really curly so if it was raining it could make it go back to normal!!
TJ, 11, England
"I think it is a great idea, I wish they put some in my school!"
Kiranjit, 11, Leicester, England
"It's very important as my hair goes all frizzy."
Lauren, 12, London, England
"Yeah because it could look gross."
Caitlin, 10, Worcester, England
"Of course it is important to look good at school."
Rachel, 14, London, England
"I think it's important to keep fit and look good. So sport and straighteners go hand in hand!"
Emily, 12, Glasgow, Scotland
"I like it!"
Jessica, 12, London, England
"I think it is a good idea but the school its wasting money."
Emily, 10, Birmingham, England
"I wish it would there were straighteners in my school because it's a wonderful idea. But it may get a little crowded!"
Kiranjit, 11, Leicester, England
"I think its very important how you look as it shows other people that you care."
Dan, 12, London, England
"I think most people are kind of pressurised into looking good for school. But while I think that looking good for school isn't really a bad thing, you shouldn't go over the top."
Paige, 12, Norfolk, England
"I don't think you need to look your best but it depends what school rules you have."
Lydia, 10, England
"I think it does matter because you feel confident when you look good and you work harder. I like the idea of having straighteners at school because it means girls won't be so worried about what their hair looks like when they are doing PE. But I also think that it could make girls become a bit obsessive with how they look."
Jasmine, 13, UK
"For primary schools or secondary schools? Secondary schools, ok that's a bit pathetic but for primary schools?! That's just encouraging them to be obsessed with their images. Get rid of the straighteners and get some discipline instead!"
Cherry, 14, Liverpool, England
"Yes because at the end of PE your hair can go back to normal."
Ayaan, 10, London, England
"I think it's a great idea but some girls are obsessive with their looks so it could get out of hand! Like if you were late for your lessons and you'd just had PE then your excuse would be, 'I was straightening my hair'!"
Olivia, 12, England
"I think it's a good idea because you don't want to be walking around with your hair all messy!"
Mariam, 11, Glasgow, Scotland
"I think this is a good idea."
Hodan, 11, London, England
"I would rather bring a comb to school than straighten my hair with a straightener everyone has been using."
Susan, 10, London, England
"I think you don't have to look nice. Just be yourself and you will be fine."
Kelly, 10, England
"Well, I think it is important."
Melissa, 14, Swansea, Wales
"I worry a lot about how I look. I spend ages trying to make my hair look nice!!"
