Three months later, after using the serum every other night, my hair is dramatically longer. I have also had a haircut where I lost quite a bit of volume, so the shape is more flattering.
The serum itself smells a little minty, is very fresh and is the consistency of water. I apply it all over my scalp and go to bed. It dries very quickly, doesn't make a mess couldn't be easier to use. It is also vegan and cruelty-free.
