Costco Shampoo – 8 Months Rotation

I shampoo every day, rarely twice a day.  And I have long hair, way below my shoulders.

I dated my bottle of Kirkland Signature shampoo when I opened it on November 7, 2012.  Today is July 7, 2013.  So, a bottle of Costco shampoo should last you 8 months.

The secret is to use just the amount you need.  I am not saying you should use less than you need.  I use plenty amount of shampoo.  I just don’t use more than I need.
