I bought some Rosemary Oil for my hair/scalp. The one linked.

My hair is ok but at 40yo it's not as thick and full as it was. I picked up the Rosemary oil in store, but now reading the reviews loads of people are saying it's made their hair fall out and burnt their scalp.
Has anyone got any experience?
