Hair loss

I am at 260lbs. today. That is awesome. But the hair loss I am having is shocking. I am losing so much hair. I had my hair cut short this past weekend. It is still shocking. Also I have been having headaches the last few days and I don't know if it is because of all the smoke in the air or what. It has been so smokey here the last few days that I have not been able to go walking in the morning. Hopefully the smoke clears soon so that I can go walking. I love getting up earlier to walk for a 1/2 hour.
