The itch and dandruff can be helped by taking olive leaf extract internally 500mg 3x /day, building up to 6x/day. I have had good success growing my hair back using a laser therapy pen about 10min/day for a month. Brought back hair to a bald spot in the front of my head. I am pretty sure it was due to some very stressful situations I was going thru at that point in my life. This is the laser I used: http://energyhealersteve.com/the-laser-therapy-pen/
