I at first had a hard time knowing how to get the gel out of the tube; repeated turns on the end didn't seem to get anything out, but I thought maybe it was really thin, so I brushed my eyebrows.  Then after about a week, a glob of serum came out.  I have been using it for about 5 weeks (not counting the 1st week when I was actually just brushing my eyebrows with no serum.  I am still not sure how much serum I should be using.  However, I have noticed slightly more growth although some hairs are really dark and grow in crazy directions.  I am continuing with it and am trying to use it twice a day now.
