Answer 2

Quite simply, it is collected fibres from your clothing. There's probably a little dead skin in there too, but the majority of it is small fibres from your clothes. Contrary to popular belief, evidence suggests that belly-button fluff comes up from underwear rather than down from your t-shirt or top.

We all have body hair to some degree. Women tend to have fine, almost invisible body hair, while men's hair is coarser and more visible. The hair drags fibre residue up from the 'pants' area until it congregates in the navel.

Karl Kruszelnicki, a physicist at the University of Sydney, Australia, conducted a major study2 of this strange occurrence over the space of a year. Just under 5000 participants answered his survey from across Australia and elsewhere, and over 66% admitted to experiencing fluffage in the naval region.

One theory suggested that hairier, overweight people are more likely to produce fluff, so some of the participants were asked to shave their stomachs to see how this affected the results. Though the findings were inconclusive, Dr Kruszelnicki did find that a large proportion of the shaved subjects noticed a decrease in the amount of fluff production, presumably because there were no hairs to carry the fluff over the curve of the bellies. However, some of the slim, hairless, female participants also confessed to experiencing fluff build-up. Kruszelnicki deduced that this might be down to certain bodily movement that continues to move the fluff into their belly buttons without the involvement of body hair.

It has been observed that belly-button fluff tends to be of a blueish tint. Sometimes it looks a little grey, sometimes purple, but generally it's a pale blue colour. Most clothing has elements of blue or white. The dyes in black clothing, for example, are often not actually black but a very dark blue.

If you have a clothes dryer, have a look at the lint filter - that tends to be blue too.

Answer 3

Belly button is fluff and grey coz due to our clothing that rub against the belly button and fluff from the clothing material goes in the hole, and most of us dont bother to clean it thats why its dirty grey..simply clean every time you have shower or bath. simple

Answer 4

Because it is flaking dry skin and has nothing to do with the colour of your clothing.

Sorry darling, but I must tell you that belly button fluff is usually and indication of insuffient bathing/showering. This gives the drying surface skin time to accumulate within the belly button cavity.

Please don't hate me, thumbs down me, it's not my fault. It's a biological fact.
