Hi Penningfarthing. I had a shortish bob but luckily my hairdresser had experience with cold cap and knew it would go bald underneath so advised the one length bob rather than the graduated one I wanted. You keep all of the top layer of your hair albeit it thins out a lot but you sound like me where you are lucky to have thick hair to begin with. I found by having it slightly shorter then I didn't have to brush it quite as much but that being said I am still washing, brushing and blow drying it every day which goes against what I read but it's worked for me. If you can try it I do recommend it as it really has boosted my moral on the days I've been low trying to get through chemo, thinking about the masectomy and reconstruction still to be done, I've felt at least I still have my hair which has cheered me up. Good luck.
