My eyelashes have definitely gotten thicker (especially the lower ones) - I doubt about any length increase since I was quite "gifted" in this area from the beginning. As for eyebrows, I went for neutral mode, by thinning them out from the bottom. I did not had to shape them much as after I cleaned up "all the mess" they turned out to be naturally curvy... I have not noticed that hairs there are thinning out much, but I dont stress about them. But! One thing which I definitely noticed - ever since I started to use coconut oil for the night as a moisturiser, I have dabbed a bit on my eyebrows as well and they have visibly benefited from that!
