Glossary Transdermal Estrogen

delivers estrogen through the skin via patches or gels

Transdermal Estrogen refers to a method of delivering estrogen through the skin using patches, gels, or creams. This form of hormone replacement therapy is often used to treat symptoms of menopause, such as hot flashes and osteoporosis, by maintaining more consistent hormone levels and potentially reducing the risk of side effects compared to oral estrogen.

learn Estradiol

an estrogen promoting hair regrowth more commonly used in women

How does topical Estradiol compare to oral Estradiol in treating alopecia? Topical estradiol delivers hormone to the scalp with less systemic exposure, but evidence is thin and it is still a hormone. It needs a doctor's supervision, and people with estrogen-sensitive cancers must not use it without medical approval.
