Surprising Hairline Test: Quick, Windproof Grey Concealer Showdown We were skeptical but intrigued by SEVICH Instantly Hairline Shadow, a dark brown powder designed to tackle thinning grey roots. Applying it was surprisingly effortless—just a light dusting across the hairline, and voilà, our greys vanished. The windproof and sweatproof claim held up, too; even after a brisk walk, the concealer stayed put. We love how versatile it is for eyebrows and even sideburns, offering a seamless, natural look. The powder’s fine texture blends effortlessly without fallout, making it perfect for on-the-go touch-ups. While it’s not a permanent solution, it’s a hidden gem for quick fixes. If you’re tired of grey resealing methods, SEVICH proves to be both forgiving and effective in our surprise test.
