Hair of the Buddha

I had heard that there are Buddha's hair relics and also seen some Buddha rupa (images) that showed Buddha having hair on His head.

The Bhikkhus are all bald shaven, are the creators of the Buddha images making a mistake?

Thus, I asked Sayadaw U Vimala before yesterday's lunch dana. Sayadaw said the Buddha had hair on His head and not bald shaven as with the other the 32 greater and 80 lesser marks.

This clarify a nagging feeling that I had when I observed my Buddha rupa in my house.
