Horsetail tea - drink it or apply to scalp?

[MissHair]

I just bought Horsetail tea. I've heard it's a natural remedy for hairgrowth, usually this herb is in many ''hair pill'' ingrediences. Which way do you guys prefer to use it? By just drinking the tea or by rinsing your hair with it? Apply topically on scalp? Or all of the above? Does anyone had any success with this?

I used to drink it (nasty taste, so I stopped). I never put it on my scalp.
