Yes. Hormonal therapy can help prevent hair loss if your hair loss is related to a hormone deficit. For women, estrogen and progesterone can help keep your hair in the growth phase, allowing your hair to stay on your head longer and grow faster.
If you notice thinning, it could be because of a decline in these hormones during menopause or after. When you add estrogen and progesterone during hormone replacement therapy, you can see a nice restoration in the balance of these hormones and impressive results.
Many women see a halt in hair loss and some even see an increase in hair growth.
