Hair loss is typically due to disease of the hair follicles, which could be the result of skin allergies, flea bites, or certain endocrine diseases such as Hypothyroidism and Cushings disease. Below are articles I wrote on all of these conditions, respctively:

You can approach this by keeping it simple and treating the haricoat and skin directly. I would supplement the dog's diet with a good canine dosed omega-3-fatty acid supplement. Omega-3's condition and nourish the skin and haircoat, while blocking allergy reaction pathways in the body. The two brands I prefer are 3V caps or DermCaps, which you can find at your vet, possibly at the pet store, or online.

In addition, I would find yourself a good oatmeal based, omega-3-fatty acid based shampoo and leav in conditioner. These types of shampoos and conditioners condition and nourish the coat, while naturally decreasing follicular inflammation.
