Black jeans fade no matter what you do, but you can definitely slow it down. The inside-out wash thing is solid, though I'd actually argue cold water matters way more than people think - I've seen folks do everything right but then throw warm water at their jeans and undo half their work. The detergent advice is spot on, but one thing I'd add: if you're not already doing this, try soaking them in white vinegar before the first wash. Sounds weird, but it really does help set the dye and I've noticed a real difference with my own pairs.
Turn them inside out every time you wash - that's the biggest difference and most people skip it. Wash in cold water with a gentle cycle, use less detergent than you think you need, and skip the dryer if you can; air drying keeps the dye from setting deeper into the fabric. If you're really serious about it, soak new jeans in vinegar and salt for a bit before the first wash to help lock in that color.
Hang drying makes a huge difference - I stopped using the dryer on mine years ago and they genuinely stay darker way longer. The heat from the machine fades denim faster than anything else, plus it breaks down the fibers. Cold water wash with minimal detergent is important, but honestly the real game changer for me was just letting them air dry, even if it takes overnight or longer. Your jeans will last noticeably longer that way, and the color holds up so much better.
