Which natural way other than using olive oil can prevent loss of eyebrows?

I have been diagnosed with thyroid lately, and it has resulted in loss of my eyebrows significantly. Presently I am using olive oil over my eyebrows, to promote some hair growth; however, it doesn’t seem to work effectively for me. Although, it definitely has stopped the hair loss, but there aren’t any new hair grown over my eyebrows. I wanted to know from some skin expert whether there is some other natural way to grow my eyebrows again! I shall be extremely grateful to you for an appropriate advice! Thanks.
