The Irish Spring works well at keeping the deer at bay but be super cautious doing that if you have curious dogs. My dog loves anything that smells pretty and he ate one of the little bags. Normally that would only be a minor problem but in our case the drawstring got caught on his pyloric valve and the bag could not pass through his intestines. We don't know how long it was in there causing havoc but by the time he showed symptoms and we got him to the vet he required major surgery which involved removing 20" of his intestines. He was in the doggy hospital for 18 days. The bags had been hung high up, out of reach, in the shrubbery but he apparently stood on his hind legs to reach this one.
Perfumy hair sounds pretty safe if you have curious pets.
