Hello,
Of course changing your diet to get your hormone levels right is the primary thing to do to stop hair fall permanently. In the meantime, you can try some herbal remedies as there are many traditional herbs that are actually helpful for preventing hair thinning.
Jojoba, lavender, rosemary and burdock root are some of the hair oil options you have. Additionally,
amla,
brahmi and
aloe vera are some of my favorite remedies. I prepare the hair wash and pack at home myself as the store bought ones are likely to contain some additives and preservatives that I would not want to put on my already damaged hair

. I have attached some sources for your help. Hope this helps
