Does Puppy Boost by Newborn Animal Care (FRANCE) help alleviate demodex in dogs?

My English Bulldog suffers from demodex. We brought her to the vet for treatment (ivermectin and dips)which was very expensive, she was cured but had a relapse. This time around we are giving her Ivermectin injections (we know the correct dosage and administration), bathe her with amitraz soap. The amitraz seemed to aggravate the demodex as it would turn scarlet after the bath and we found the amitraz to be extremely toxic and harsh. That was the last amitraz bath. Since then we have been giving her neem leaves with her food and soaking her in neem tea, we had also been rubbing fresh aloe vera (straight from the plant) on the demodex and we have also been giving her puppy boost. Her condition improved drastically overnight. Which of these treatments do you think did the trick? So next time we don't have to do so many things. Thanks!
