The attack occurred while hairdresser Eduardo Ferrari was serving another client in the salon. Imagens from the establishment’s security team captured the exact moment of the attack.

The hairdresser reacted with astonishment and quickly walked away. The woman was immediately restrained by other employees and the site’s security guards, preventing the aggression from taking on greater proportions. The team’s readiness was crucial for everyone’s safety.

Laís Gabriela Barbosa of Cunha, after being immobilized, explained the reasons for her anger in a video that circulated on social media. Ela claimed deep dissatisfaction with the bangs cut performed by Eduardo Ferrari, describing the result as “looking like Cebolinha”, in reference to the comic book character. The client stated that her hair was chopped with razor scissors and that she had suffered a “chemical cut”. Ela also mentioned having sent messages via WhatsApp to the salon, without receiving a response for two days, which would have intensified his frustration.

Motivações and the attacker’s version

The attacker detailed her complaints in recordings posted on the internet. Além of aesthetic dissatisfaction, Laís Gabriela Barbosa of Cunha reported having uttered a homophobic insult against the hairdresser before stabbing him. “I offended him and said: ‘you bastard, fix my hair'”, he stated in his statement. The woman assured that she had proof of the condition of her hair before and after the procedure, arguing that the “chemical cut” had been a determining factor in her indignation. Essa claim, however, is technically a hair break caused by chemical reaction, not a physical cut.

The client had undergone a hair procedure in the same salon approximately 30 days before the incident. Ela returned to the establishment expressing dissatisfaction with the result and demanding the refund of the amounts paid. The situation quickly escalated from a verbal argument to physical aggression, highlighting the intensity of the client’s anger. The security images showed Laís’s coldness when he took out the knife and attacked the professional.

The victim’s status and the legal directions of the case
