Expert Response

Deer behavior is unpredictable.  

Although some people swear by the efficacy of the measures you have mentioned, none is considered reliable by wildlife and horticultural experts. 

Experts at the University of California say this:

"Some home remedy repellents are used because in theory they produce odors thought to frighten or repel deer from an area. Examples are human hair, bars of soap with an intense fragrance, and predator feces or urine. These substances may repel deer for a day or a few days, perhaps more because of their novelty value rather than any inherent repellency. Most such odorous materials, as well as many commercially sold deer repellents, have not proven to be satisfactory in protecting gardens from deer damage."
