Here's what worked for me.
Make the following blend of essential oils:
Lavender 5 drops
Geranium 4 drops
Cypress 4 drops
Rosemary 3 drops
Juniper 2 drops
Cinnamon 2 drops
Mix these together, shake well, then take one drop of the blend and mix it with one ounce of water, shake well, then apply to your scalp each day after washing your hair.
This made a huge difference for me, I re-grew a lot of hair. It took about 9 months to see results. Don't put the undiluted oil on your skin and don't get any in your eyes.
Good luck.
