Thank you for this tip!!! I am 4.5 months post op, and I started losing SO much hair a couple weeks ago. After only a couple weeks, I have lost at least 50% hair volume. I fear I will be bald in a couple more weeks! It is so bad, I try not to brush my hair much. I barely pick through my hair and I have a huge ball of hair in my hand! I am SO going out and buying this tonight! I will let you know how it works.
