The FIA is aiming to introduce a second version of the Halo for 2021, while also widening its use in junior formulae.
The introduction of the halo received a mixed response among the motorsport community but its popularity has grown amid two incidents in Formula 1 and Formula 2 this year.
Fernando Alonso’s McLaren rode over Charles Leclerc’s halo in the multi-car pile-up in Belgium while earlier this year in Spain there were tyre marks on Tadasuke Makino’s halo in the wake of a collision with Nirei Fukuzumi.
Years of research into head protection has led the FIA to the development of the halo and in line with their approach on safety, they do not plan on slowing down in their research.
FIA Formula 1 Race Director Charlie Whiting said: "There is further research going on for a new iteration, probably 2021, for a possibly more aesthetically pleasing to some.
"But that’s not the predominant reason for doing it. But I have to say the halo project was the most thoroughly researched project we’ve ever done, by a long way.
"We put an awful lot of work into trying to look at all the incidents where it may have helped, you’ve probably seen the presentations, we tried to assess what would have happened with or without it.
"It was a massively complex piece of research, it would have to be similarly thorough if we want to do another version of it."
In a separate video released by the FIA, Whiting and F1's Managing Director of Motorsports Ross Brawn discussed the halo and its development.
"We've got it in Formula 2 and we will have it in Formula 3 next year," Whiting added.
"Any new single-seater category will have to have to the halo, then we'll gradually introduce it into Formula 4 as and when a new car comes along.
"It is definitely filtering down and it will be on the Super Formula cars in Japan too."
