I'd point at the sorbitol too, not just the glycerin as a possible dryness causer. Sorbitol is both a nonionic surfactant and a humectant, and there's even more of it than there is glycerin in LALSG. Maybe try layering some AIF under the LALSG as sort of a buffer? You'd still get the hold of LALSG but there'd be another layer of gel between it and your hair that would hopefully help prevent dryness. Or, if your hair likes a bit of oil, try sealing between your LI and the LALSG.
