I'm generally wary of "leave it in overnight" hair products because most of them transfer straight onto my pillowcase and leave my roots looking unwashed by morning. IGK's Glow All Night won me over because it actually delivers the shine payoff without that trade-off.
It's built to work while you sleep, targeting shine and smoothness so hair looks noticeably glossier by morning rather than flat or product-heavy. IGK has built its whole brand identity around a fun, editorial approach to haircare, and this product fits that same playful-but-effective positioning.
I noticed the biggest difference on second-day hair, which usually looks duller for me - this closed that gap noticeably, giving strands a healthier reflective shine without weighing fine hair down.
It's listed at $68.00 on IGK's site.
