Black jeans don't fade because the colour is weak, they fade because of how they're washed. Here are the five washing habits doing the damage, and the cold-wash, low-heat approach that actually keeps darks dark.
1. Washing in hot water
Heat opens up the fibres and strips dye out with every wash. It's the single fastest way to turn black jeans grey.
2. Overdrying
Leaving jeans tumbling on high heat long after they're dry bakes fade lines into the fabric and breaks down the fibres faster than any wash cycle.
3. Washing right-side out
The outer surface is where all the friction, rubbing and fading happens. Washing jeans right-side out puts that surface directly in harm's way.
4. Overloading the machine
A packed drum means jeans rub hard against buttons, zips and each other for the whole cycle. That friction is what wears colour away at the seams and pockets first.
5. Using the wrong detergent
Standard powders are often built for whites, with brightening agents and bleach-based ingredients that actively strip colour from dark fabric wash after wash.
