More information

There are only a small number of studies of the effects of alfatradiol on hair loss, and there is no clear conclusion on whether it is effective 1.

In the UK, the more proven options of minoxidil and finasteride are used instead.

Alfatradiol treatment is not funded by the NHS.

You can read more about hair loss treatments on the NHS Choices website.
