Telogen effluvium!!
It sounds like something Harry Potter would shout in a battle over evil in the newest “Harry Potter and the other jeweled mirror of evil controlled by that good guy that was really a bad guy” movie.
relax HP fans… I like the movies
I was starting to wonder if someone had put a spell on my head for rapid hair loss.  Then I remembered that it has happened before. Three times before to be exact.
I remembered that the birth of each of my children caused my hair to fall out in giant clumps and turn my showers into baths.
I also remembered that, while this is COMPLETELY NORMAL and will stop, it can be aggravated by poor nutrition and stress.  **insert sound of me googling “postpartum hair loss” **
While most of what I read was a “just wait and it will stop” recommendation I did stumble upon some suggestions:
From American Pregnancy’s Website:

Recommendations for Your Hair During Pregnancy and After Delivery:
There are a number of things that you might do to have healthier hair and/or reduce hair loss during pregnancy and after delivery:

• Consult with your health care provider to ensure a proper balance of hormones
• Avoid pigtails, cornrows, hair weaves, braids and tight hair rollers which can pull and stress your hair
• Eat a diet high in fruits and vegetables, which contain flavonoids and antioxidants that may provide protection for the hair follicles and encourage hair growth
• Use shampoos and conditioners that contain biotin and silica
• Hair is fragile when it is wet, so be gentle; avoid fine tooth combs
• If you need to use blow dryers and other heated hair instruments, try to use the cool setting
• Supplement your diet with the following nutrients:
• Vitamin B complex (Catergory A)
• Biotin (Possibly safe; orally and appropriately)
• Vitamin C (Catergory A)
• Vitamin E ( Likely safe if amount does not exceed the RDA; possibly safe if it does)
• Zinc (Likely safe when used orally and appropriately; likely unsafe when used orally in high doses)

Telogen effluvium is the excessive shedding following pregnancy that can last up to six months.
