During pregnancy, hormone levels put your hair in its resting phase, so you do not shed as much hair as you normally would on a daily basis. I can attest that during my last pregnancy I did not shed one single hair for 38 weeks! I absolutely loved it and had awesome thick hair. So, ladies, if you're pregnant right now, love it while you can. Once you deliver, your hormones are going to crash and you can expect that two to three months after delivery, your hair is going to shed. It may seem scary and overwhelming to you. Don't panic, and know that you are not alone. It is OK to talk about it and I would encourage you to do just that and give your hair stylist a call.
During this time, make sure you are still getting proper nutrition (lots of fruit and veggies) and vitamin supplements (vitamins B complex, C, E, biotin and zinc). Make sure you take extra special care of your hair as well. Be careful when combing (especially wet hair), lay off excessive styling and the use of blow dryers, don't sleep on your hair when wet or tie it back when wet (ever, but especially now) and make sure you are using a quality shampoo and conditioner (I recommend Nioxin products that are made especially for thinning hair).
Remember that hair loss post-partum is temporary and it will stop. Plan on it being completely over within six months of time. In the event that it doesn't seem to be stopping and/or it is worse, contact your healthcare provider to assure you don't have a thryoid issue or any other health problem. Also note that if your hair is falling out during pregnancy, you should be concerned and contact your doctor immediately. This could be a sign of a vitamin definicency and/or thyroid problem. Our hair and its condition is a great way for us to know the overall health of our body, so pay close attention to it.
