What are your opinions on topical estradiol patches for estrogen replacement therapy and female hair loss?

It's possible it could be contributing to hair loss. I suggest seeing a hair loss expert now to evaluate and go over your condition and provide you information about your best treatment options. I do prp with progesterone injections to get the best results with hair growth and quality. I also have all my patients use viviscal, rogaine, and propecia when getting prp. See an expert. Best, Dr. Emer

For some women estrogen patches and topical estoegen may stimulate hair growth. For others it does not and yet for others it triggers hair shedding and hair loss. One would need more information and to understand the entire profile of hormones to really offer more concrete advice. But certainly estrogrens trigger hair loss for some.

Estrogen is not a sole reason for hair loss. İt is important to find out the cause of  hair loss. Female pattern hair loss or genetic alopecia is the most common reason of hair loss in women and it is more common than it is thought to be. 25% of the women at the ages of 35-40, 50% of the women at the ages above 40 suffer from hair loss. 20% of the women with hair loss have a positive relative who suffered/is suffering from hair loss. Other reasons of hair loss are: Hypo- and hyper-tiroidism (hair loss may be one of the early signs of thyroid dysfunction, and hair loss stops after treatment); polycystic ovarian syndrome (an inherited ovarian disease, seen in 10% of the women during adulthood); pregnancy-related hormonal changes (temporary hair loss which can be seen during pregnancy stops after birth)..

The reason of the hair loss may related with factors other than genetic like connective tissue disorders, stress, anemia, lupus, medications, hormonal and seasonal changes, nutritional problems, severe diets, bulimia, protein/calorie deficiency, zinc and essential amino-acid deficiency, mal-absorption (intestinal and digestive problems), A-vitamin excess, general anesthesia, affective mood disorders.
So you may need to have a full exam with an hair surgeon, internist and/or endocrinologist to find out any reason for hair loss.

Hair loss is a known side effect of the Estradiol patch . You should speak with your prescribing doctor about this
