Dear chenaj,
I'm glad the garlic treatment worked for you! But it's impossible not to shed at all. We lose about 50-100 hairs a day.
And if your hair is MBL - OMG, that's awesome

- and you only detangle once a week a pingpong ball amount of shed hair doesn't sound much to me.
Curlynikki recently did this
post about shedding after a pregnancy. Maybe you will find some helpful tips there, too.
Do you have a fotki?
