I have really long hair, don't brush it OR wash it as often as I feel I should. I thought it would be in terrible condition with the way I treat it, but when I went to the hairdresser after not having it cut for about a year, they said it was actually in good condition.
The cold weather puts me of washing very often, as I'm not one for blow drying so I hate how long it takes to dry in winter. The brushing though is just pure laziness. Shhh
