Hello I am 70 years old female and have suffered head and scalp sweating mostly in the summer on days when it is hot. I have never liked the heat but it got worse after the menopause. On days when it is hot I find it hard to go out anywhere as very soon my hair is soaking wet and sweat is running down my face and neck apart from feeling drained. I remember preparing for my daughters wedding trying to dry and style my hair and I could not get it dry. It was a very warm day in July. I had a large hat so it did not show in the photos. I too have an under active thyroid since I was a round 45. I don't think it is that because a few years after starting the thyroxine my other daugher got married again on a warm day and I did not have problem (this was before menopause which was not until my early 50s).
I have put up with it for years it also happens in a hot restuarant or when cooking a roast dinner for the family. I also suffer from anxiety and we are going to a family wedding in August in the south of England. We are now in the north and will face a 4 hours journey down plus the wedding. I am dreading it if it turns out to be a hot day. I realise it might not be as we never know in the UK how the weather will be. Only last year I visited family for grandsons birthday but had to come home early as it was so hot I could not cope with it nor could my husband who has other health problems. Any hints would be much appreciated. I don't think people realise how this problems affects us. I know that nearer the time I will be getting anxious and praying it will not be hot on the day which is not a nice thing to think as they will want a nice sunny day for the wedding if possible. I don't think doctors are really interested and besides I have other health problems to deal with.
