antdad said:According to Dr P on average there are 14 grammes of hair in a 21mm brush where there are 1000 hairs per gram.
According to my calculations a 28mm brush will have 25.65 g of hair, in other words nearly twice as much (83%)
which is why you need much more soap with these fat boys
I ope you found that as interesting as I did, it was a short diversion from counting how many brush hairs I have lost in a week. :ugeek:
antdad said:A 32 mm diameter brush will have 32,560 hairs :shock: ...using (area)2 for calculations. :ugeek:
antdad said:If that BK12 lost 2 hairs a day, every day for nearly 15 years it would have shed about a third of its hair which is basically what has happened to me.
