1) Raise a Sylveon. They come with Cute Charm by default, and of all the Pokemon with it, they're the most likely to be male. Mine was level 50 when I did the chain.
2) Have a Pokemon to False Swipe the Salandits and neutralize the shiny. Most people use Decidueye. I use Absol, because it can learn both False Swipe and Thunder Wave, and also because I just like Absol better.
3) Grow some berries. You will need Leppa, Sitrus, and Pecha. Also some Rawst, just in case.
4) Start with Sylveon in the lead, and run around until you find a Salandit. Switch to your False Swipe mon, swipe, then switch back to Sylveon. Use the Adrenaline Orb, and just keep knocking out Salandits.
Every now and then, you'll have to switch out to your False Swipe mon to swipe again, just to keep the chain going. As long as Sylveon is on the field, you'll have a 2/3 chance of seeing a female Salandit over a male. You'll unfortunately miss out on some egg moves (Belch, Fake Out, Knock Off, Sand Attack, and Snatch) and the nature is going to be a gamble, but this is the most reliable way to get a shiny Salazzle. Mine is Rash.
