Slowly but surely, the hormonal balance changes after giving birth, and estrogen levels drop. This causes your hair to enter the shedding phase, resulting in hair loss. Now, the hairs that would normally have fallen out during pregnancy are shedding, in addition to the normal daily hair loss. This means temporarily experiencing extra hair loss, but fortunately, this is only temporary. Even though you may find clumps of hair in your brush and notice bald spots, in most cases, your hair will grow back to its pre-pregnancy state within a year. This type of hair loss, where the hair growth cycle is disrupted, is called Telogen Effluvium and can be triggered by various factors.
