Hair product that starts with a g and ends with a d that makes your hair grow thicker?

I just finished with chemo and was told by another patient that there is a hair product that made her hair grow back in thicker after chemo and it started with a g (I think) and ended with a d (more sure about this). Forgot what the actual word was. Does that ring a bell with anyone?Hair product that starts with a g and ends with a d that makes your hair grow thicker?
props for ending chemo. im very proud of you.


as for the hair, im not sure, but i know that horse shampoo makes your hair grow faster. i used it once when i had my hair cut badly. it worked for me, it could work for you.
