What is the ruling on getting a haircut at barbershops despite the father's refusal, given the ability to avoid diseases by using private tools?

Obeying one's father is obligatory in matters that are permissible, provided his command has a valid purpose or a recognized benefit. A father's command to his son not to go to barbershops contains a recognized benefit and interest, due to the possibility of transmitting diseases. The risk of infection is not limited to the tools but also includes the barber chair, the surrounding environment, and the barbers themselves. The questioner must obey his father out of filial piety and kindness towards him.
