I love FSG, but it's no BRHG dupe. FSG has very light hold.

AIF and HESMU are the closest I've come across, but I haven't tried much that's not drugstore.

There are a couple gels from Sally's people swear by (not talking about ecostyler) - I think one is bioterra, and another is... I can't recall the name, but I think it's thinner, more like a glaze.
