Why is the haircount increasing in the placebo group?
Even when you look at the average of all subjects it is increasing after one year.

I'm curious about this too!

[tizzle]

maybe there were many hair follicles which went from resting to growing phase (sorry i dont know the scientific terms)

I read a study once (i think it was a Fin Study) where i saw the same thing

It almost shows that there is a tendency to be over generous. Human error still occurs I'd imagine when counting hairs and when your conducting a study into a treatment for hairloss, you'll always want to see more hairs. But the people conducting the study do not know who had the real injection or placebo.

The hair count increasing in the placebo group is probably a mixture of margin of error and the nature of the hair cycle

Sounds logical and in fairness all results come with a margin of error +/- a certain %.

so an increase of 5% (+/-6%) which means it could and increase of 11% or even a decrease of 1%.
