Hi and welcome to MM Nicky84
Can you tell us a bit more about yourself? You say you are in surgical menopause - I assume you had a hysterectomy? Did you have endometriosis?
You have been given a combined HRt which is normally given to women who still have a womb(uterus) and need to protect the lining with progesterone. Normally following a hysterectomy a women only needs oestrogen but if you had endometriosis then HRT with progesterone is still prescribed because there is build up in other areas that still need to be shed.
I would certainly agree with the specialist about Femoston and a higher dose as well. Femoston has a kinder progesterone and suits many women very well.
If you look under :
http://www.menopausematters.co.uk/perimeno.php there are the different preparations and it explains that certain progesterones are more testosterone based and this can cause more side effects and could explain the thinning of the hair. Femoston contains a progesterone that is closer to our own hormones. Also a higher dose of oestrogen might help with the dry skin and other problems that might emerge due to oestrogen deficiency as you are so young.
Unfortunately Elleste is one of the cheapest preparations and GPs tend to go for the cheapest first!!!
