Hi Jenny
I went for a zero shave so there was not alot of hair left after that! I am about to have cycle 4 and although my hair is almost gone on top and sides there are still many determined folicless hanging in at the back. I wash my scalp with the same soap I use on my body (a medicated liquid soap for dermatitis) and give it a rub with sorbolene or whatever moisturiser I have handy. I found the moisturiser really important to avoid the flaky/dry skin look. Also, dont forget the sun block. Although I wear a hat most of the time, its nice to be able to take it off if you want and not have to worry about sunburn.
All the best
