You panicked the second you saw it in the mirror, your hair is at least three shades darker than what you asked for. Now you're stuck wondering if you should wait it out or call your Hair Color Salon Bronx, NY to fix it immediately. Here's what actually happens if you wait. Dark dye fades faster than you think, especially if you wash with hot water and clarifying shampoo. Within two weeks, you'll lose about 30% of that intensity. But if it's truly black when you wanted brown, waiting won't help enough. The longer you leave it, the more the color sets into your hair shaft. If you're already thinking about Hair Extension Salons Bronx, NY or need a Hair Cut and Blowout near me to salvage the situation, don't wait more than 48 hours to call.
