To stop hair fall best are home remedies like onion paste, egg, etc. Eating jaggery in the morning with warm water has personally helped me a lot. You can also have fish oil tablets (very safe and no side effects as such).
I was having the same problem but right now is less. I tried flaxseed gel, aloe vera gel and coconut oil. Mix them and keep for at least 1 hour after that you can wash with any shampoo you use. Also it depends on your stress level too so try to meditate too.
You can surely use Aloe vera to treat hair loss. It also soothes the scalp and conditions hair. You can apply pure aloe vera gel to your scalp and hair a few times per week. You can also use shampoo and conditioner that contain aloe vera.
