I heard from different people that Horse shampoo or Bergamot essence helps hair growth. you usually add the Bergamot essence to your usual shampoo, but seeing that I wanted something that really works, I just combined the two. - I have longish hair for a guy, but I felt a random impulsive desire to shave it off one day, I did...but after a week or two, when my hair reached an akward length , I simply needed it to get past that akward stage as quickly as possible. - I'd recommend you try both, and some of the comments above suggest certain brands of Horse shampoo that worked for them, so it might be worth while to look into buying a certain brand of Horse shampoo that someone knows works well.
