A ‘set’ of hairs representing the upper lip, with an 8 week anagen phase and a 6 week telogen phase. The pink boxes are the anagen phase hairs, beige boxes are catagen and the green boxes are the telogen phase hairs. The time axis is pointing downwards (which is a bit odd – I know!!)
Now, this is where I noticed the first interesting thing.... The above 28 hairs represent EVERY hair in the upper lip area because every hair in that region will be in one of these stages in its growth cycle (assuming a 20 week anagen phase). So, simply by adding the durations of each phase, we can find out how many hairs are needed to represent all of them (using a 1 week temporal resolution)!
I coloured coded each phase so it is easy to see where the follicles are at each stage (see below). Next, I “killed” some follicles by turning them black – these were the follicles that were in anagen at the time of ‘treatment’ – week 0.
The black boxes represent all the dead follicles following treatment. In this case, these follicles were treated at week 0.
