Losing hair at your crown while scalp cooling isn't uncommon. It can occur for a number of reasons. The first thing to consider would be cap fit – loss at the crown may be a result of a cap that is too small as the blue inner cap is not making contact with your scalp. Speak to your clinical team and consider resizing for a larger inner cap size. We would also recommend re-watching our ‘Putting on the Cold Cap’ How-To videos - particularly on the lacing technique, as this can improve contact with the scalp significantly.
The other thing to keep in mind when it comes to crown hair loss is that the top of your head is the hottest part of your scalp. The cap therefore has more work to do in this area to achieve the optimum temperature to prevent hair loss.
If your cap sizing is correct and your cap has been put on correctly, you are doing everything you can to reduce the chances of crown hair loss.
