Hi I have had hair loss for about 2 -3 years, pretty bad. I noticed sometimes, I felt a burning sensation on my scalp, doing an internet search I discovered it's called burning scalp syndrome and it's due to stress and can cause hair loss. I don't know if that's what you are experiencing.
I used visualization but it took a long time to get the hair growing back in, then I would get stressed out about something and it would start falling out again. (this was probably due to my own limiting beliefs)
However, I continued with visualization, did meditation for stress and took vitamins.
The vitamins I take are:
Biotin 5,000mcg
MSM 1,000mg
B-Complex
I started this about two months ago and noticed a big difference. I also use Designline Shampoo and Conditioner "Olive Oil". That has made my hair look thicker and it looks much healthier. I am getting compliments now on how shiny and full my hair looks. Before my hair was just a frizzy mess.
I haven't done self hynosis yet, but you can try this site.
