Regarding hair-fall, personally I only experienced a tiny bit on my eye brows, which went away as soon as SD went away. However, from all my research so far, it seems that topical arginine (a non-essential amino acid) may be beneficial for restoring and stimulating hair growth. However, most of the information is contained in patents (example) and not medical trials. Perhaps you may want to look for arginine containing product. Additionally, it helps in wound healing and may even act as a antibacterial. The shampoo I use, the lotion I’ve made for myself and the Restoraderm lotion I used previously all contain arginine.
This medical paper may a good read as well.
A friend of mine swears by castor oil for hair-loss, however I haven’t done much research around it.
Also, it appears that medical anti-fungal shampoos (such as Nizoral, Head & Shoulders) can also stimulate hair growth and prevent hair loss. However, I’ve moved away from these products. Personally, I believe they were part of creating my issues in the first place.
Hope that helps. All the best.
