Little Lewis Carlyle pitched up for class at Logans Primary School in Motherwell, North Lanarkshire, with wash-out blue gel in his hair.
But teachers didn’t see the joke – and his mother Leanne claims Lewis was told to go home to wash the gel out or he wouldn’t be allowed back in class.
Angry Leanne Carlyle 24, said she had to collect her upset son from school after receiving a call about his hair.
Football-mad Lewis, who is in his first year at primary school, is a fan of Rangers FC and tinted his hair blue partly in tribute to the club.
Leanne said: “The teacher told him blue hair wasn’t allowed, I think he felt like he had done something really wrong.
“He’s in his school uniform so why should it matter what colour his hair is?
“Now he’s been sent home and lost a full day’s education all because of his hair colour, it makes me so angry.
“I had to go and pick him up.
“They told me he would only be allowed back if he washed his hair, but by the time I would have done that and brought him back it would be pointless so I had to keep him home for the day.
“I didn’t have time to pick him up, wash it out and then take him back.”
Leanne, from Motherwell, said Lewis picked up the blue hair gel at his local barber’s on Tuesday (April 26) after a haircut and couldn’t wait to show his friends his coloured locks.
She said: “He was really excited about it, and wanted to show all his friends at school.
“It was only the top of his head we put it on so I didn’t think it would be a problem.
“It’s disgusting really.
“We’ve paid money for the school uniform, which is the same as everyone else’s.
“He should be allowed to do what he wants with his hair, it even matches the uniform.”
Leanne, whose youngest son Dylan, four, is due to start at the school after the summer holidays, said she is shocked at the school’s behaviour.
She said: “He has been completely discriminated against all because of his hair, it’s ridiculous.
“I’m not having him being singled out, it’s not fair.”
But the school has denied Leanne’s claims that Lewis was sent home.
Headteacher Mrs Angela Cusick said: : “When Lewis arrived at school this morning we contacted his mum to inform her that we don’t allow pupils to come to school with their hair dyed.“Lewis was not excluded, we simply asked that he did not return to school tomorrow with his hair coloured – he was welcome to remain in school for the remainder of the day.
“She seemed fine with that and offered to collect her son from school today so that the dye could be removed.
“Coloured hair is fine on a dress down day, but it’s not acceptable on a normal school day.”
Lewis is back at school today without the blue hair.
