I think that the culprit in your treatment is the probiotics you are taking; it only contains 50 million cfu per pill? You need billions in order to make progress and this probiotic is likely too weak. Its the most important thing you need for your treatment. Ideally it’d be best to take somewhere between 40-90+ billion cfu of probiotic per day and you’re only taking like .05 billion (or 50 million).
If you can do a sauna, hot tub, steam room, or jacuzzi as often as possible, this can help with the die-off symptoms. Mineral springs are a great healing tool as well.
Another supplement for die off that you can try is juniper berries which can protect the liver and kidneys (there is an extract). Milk thistle also protects the liver and is very important as well.
Also, when you can, try to increase the doseage of antifungals from 4 drops to 20+ drops gradually in time. You might want to wait to do this, but if you increased 1 drop per day and work your way up, you might notice more progress. If you’ve been taking oregano oil the last 4 months only, I would rotate to something else such as grapefruit seed extract, black walnut extract, red clover, etc.
There is a chance you have parasites which often grow in the same environment as candida; these are killed in a very similar manner as the protocol, you just need to take some different antifungals such as black walnut extract.
Lastly, acupuncture is a very great healing tool I use in my treatment and highly recommend it. It can help rebalance the body and getting it to work optimally. You can heal a variety of organs with it as well and it can help you detox. It can aid in depression, stress, and many other things.
The hair loss problem is a fairly common one; I personally feel it is caused by a demineralization problem that most people with western lifestyles have. The only way to get over this I know about is to take trace mineral supplements (such as zinc, magnesium, calcium, iodine, etc) and homeopathics. As your body heals, your hair should start to grow back or at the least your hair loss should lessen.
Hang in there!
