We ourselves love a contrasting fade in which the denim jeans or jacket reflect their owner’s lifestyle, but we also love the style of a good vintage fade. It is your choice whether you use one method or the other, but do understand one thing: if you prefer durability over high contrasted fades, don’t hesitate, regular washes will be the way to go.
Nowadays there are many detergents intended specifically for raw denim. Many of them minimize the loss of indigo. Some of those we have tried are Thunder Soap by Samurai, the one by Flat Head and another one by Studio D’Artisan. Other better-known and more affordable ones are BraveStar or Dr. Bronner. However, if you’re looking for a specific detergent to minimize the loss of indigo and you don’t want too much bother, you will find Woolite Dark in any North American supermarket or Norit Dark in Europe.
But don’t overuse it. It’s always tempting to think that more detergent = more clean and this is not quite true.
