Upgrading my MacBook (13-inch, Aluminum, Late 2008) from its original 160 GB HDD gave a number of immediate benefits:

I was considering purchasing this shirt, when a future version of myself appeared wearing the shirt saying it was definitely worth the $15.00 for eternal life and the ability to displace time and space. Still not entirely convinced, I read the product reviews with my future self and agreed that all of you were right.

I have had issues with thinning hair since I was 21. I am now almost 30. I tried a bunch of different shampoos to keep the hair I had and kept thinking that the reason I was losing hair was stress. I finally gave in and tried this stuff out. It has indeed regrown my hair and in more places than its guaranteed to work. It has also regrown hair in the front of my scalp as well as the crown. I wouldn't tell you to expect to have hair from when you were a teen but if you want to regrow what you have and at least fill out your hairline this stuff may work for you. Keep in mind everyone's chemistry is different so it may not work for you. The foam is easier to use than the liquid and acts like a mouse so keep that in mind when you're styling your hair.
