I bought this with the sole purpose of regrowing my hair. I am using it in a 10ml roller to apply to my eyebrows. After years of over plucking and keeping it super thin I am ready to grow them out and reshape into something much more attractive. I also use JBCO in a tube and wand, think mascara, to apply nightly to my eye lashes in hopes of regrowing those as well! Lastly, I'm applying this to my scalp to regrow my hair! I love the smell of it and can't get enough of this. I only wished I had bought a bigger bottle! It's a great product and I highly recommend it to anyone needing to regrow hair!
