In March 2009, I cornrowed my hair like so...
and rocked it like this for a couple of weeks. I even washed it and replait it in the same style. Unfortunately, this coincides with the telogen effluvium (shedding phase) which occurs naturally 3-4 month post-partum. (Some women lose more hair than others). For me I lost huge tufts of hair from my temples. I look like I have been wearing micro braids for too long and have traction alopecia :(
You can really see it in these shots:
hopefully this will fill in again over time as I continue to eat healthiy, take my post natal vitamins and avoid stressing the hairline.
