3 year old with back hair !?!

[Guest guest]

My preschool aged son has developed dark hair on his back and his legs

during the past 2 months. He isn't showing other signs of precocious

puberty.

I thought maybe the taurine we were using was causing the hair because

taurine is being studied as a hair-growth supplement. But I stopped

the taurine 2 weeks ago and the hair is worse than before.

Any ideas about where this might be coming from? A supplement?

Metals? His hair test is on Wednesday.

Thanks,
