Sensory Issues with Chalk?

Hi all - my girlfriend got into climbing recently and discovered she’s got a severe sensory issue with chalk. She can climb shockingly well without chalking her hands, but if a climb’s holds are already very chalky, it’s a distressing experience where she has to take a lot of breaks and wash her hands immediately after.

Have any of you seen or experienced this before? Any suggestions on how she can deal with chalky holds (eg special gloves that wouldn’t impede her climbing)? Thanks :)
