Hairdressers are seeking to have their sector moved into Level 4 of the Government's Plan for Living with Covid-19.
The Irish Hairdressers Federation says newly refreshed health and safety guidelines it has issued to members take account of new information about the virus and make it safer for them to operate at a lower level of the plan.
President Danielle Kennedy said: "Since we published our first health and safety document six months ago, a lot has changed in our response to the pandemic."
"We now know a lot more about how to control it and we decided to take a fresh look at our document alongside our health and safety experts."
The updated guidelines state hairdressers should wear face masks, not visors, as required by law.
Employees need to be aware of the difference between a close contact and a casual contact to ensure salons do not close unnecessarily, the guidance also states.
Ongoing training of employees as the pandemic continues to evolve is also recommended, while salons should be well ventilated with fresh air where possible.
The guidelines also say employees should ensure they are aware of the EU Traffic Lights system regarding clients who have travelled from abroad.
"It is important that we constantly try to review and improve how we respond to the pandemic," Ms Kennedy said.
"We hope the Government will look at this and consider allowing us to remain open in Level 4 of the living with Covid plan.''
There are concerns within the sector that if the incidence of the virus in Ireland increases over Christmas and the country is forced to enter Level 5 restrictions again, hairdressers along with other non-essential retail outlets may have to shut again.
