GFI receptacles on a multiwire branch circuit

[electric wrangler]

Hey everyone, I am researching a job at a hair salon that is going to have 10 cutting stations, each station needs two 20 amp dedicated circuits. I would like to run 12-3 to each two gang box and install two GFI receptacles, also install a two pole breaker in the panel for each run. I ran this idea past my inspector and he wasn't sure if GFI's could have a shared neutral. Hoping to get some clarification on this from you guys.
Thanks,
Mark

On the line terminals, it's okay to do.

Correct!
Each GFCI only sees current coming/going on one hot and neutral. It doesn't know the neutral shared itself before it got there.

Not unlike the service itself.

Sounds like a good plan to me.
Should be no issues with the GFCIs.

Just pigtail the 1 neutral as 2, connect each GFI with its own line connection pair.

The only thing to watch out for is if you serve anything from the _load_ terminals of the GFCIs.

You can share the neutral going to each station and to the GFCIs, just as you plan. But you have to have separate neutrals going from the GFCI load terminals to downstream protected receptacles.
