Natural after pregna: During pregnancy you have high levels of estrogen for a long period. This synchronizes your hair follicles more than usual. When you deliver your baby then your estrogen level drops dramatically. Then some women perceive a large amount of hair loss. This is only because the hair follicles became synchronized and it should eventually resolve. You can use Rogaine (minoxidil) applied to your scalp.
