You might want to try rinsing your scalp and hair with a mix of 1/2 cup of Apple Cider Vinegar and 1/2 cup of warm water. This will help the itch and make your hair shiny and healthy. Pay attention to the shampoo you're using, try using an all natural shampoo with no chemicals and never put any chemical products on your hair.
You can also try putting 3 sprigs of Rosemary and 1/2 cup of olive oil in a blender until Rosemary is completely groud and apply to any areas that you notice your hair thinning. You can do this several times a day, be patient it does help regrow hair.
