beta-sitosterol in avocado

Do you guys think it's possibly to consume 2-3 avocados every day for its amount of beta-sitosterol to have any impact on hair loss?

The reason I ask this is because I came across this article about an 81 year old avocado farmer with great hair for his age!

" For as long as he can remember, George Bliss, age 81, has been eating avocados morning, noon, and night. A second-generation California avocado farmer, Bliss loves the fruits of his labor. "I eat three avocados a day," he says with the fervor of a true addict. "I have one on my eggs in the morning, one in my salad at noon, and one with my dinner."

One avocado contains about 100 mg of beta-sitosterol. IH has stated on other threads that this should be a sufficient daily intake.

3 avacados per day is more than enough beta sit, using a beta sit supplement would be much cheaper though.
