Woman's head turns into the size of football after colouring her hair

If you are among people who colour their hair, beware of the devastating side effects it could have on you if you are allergic to any component in the dye.

A woman in Bulgaria learnt it the hard way when she was left with a head the size of a football after she suffered a severe allergic reaction to hair colour that she used. Most hair dyes come with a warning to do a patch test first before using it.

According to a report in the Mirror, Valentina Nikolova, 20, from Sofia, Bulgaria, visited a salon to get her hair coloured. However, in less than a day, she developed severe itching on her scalp.

Worried about it, she contacted her hairdresser only to be told that it was a normal reaction.

However, to her shock and surprise, the next day, when she woke up she found the top of her head swollen, but the next day, the swelling increased and she could barely keep eyes open. Her head turned the size of a football. On the fourth day, the swelling reduced but a top layer of her scalp started peeling off.

“Please, do a patch test before dying your hair, no matter what colour it is and no matter if it is temporary or permanent,” Valentina advised everyone after the harrowing experience.
