I was a bit skeptical when initially ordering. I had tried other eyebrow and eyelash serums, with little improvement. I had very short, straight and thin eyelashes. My eyebrows were very sparse, to the point I had ombre shading in order to add some structure to them.
I started my initial Nulastin order with the eyelash serum and after the first two weeks, I noticed a slight difference. After four weeks, it was like night and day. My lashes are fuller, longer and to the point that I almost don't require mascara. I decided to try the bundle (lash, brow and hair serum) and have been extremely impressed. Now, my eyebrows have growth where I thought there were never be eyebrow hair. The thinning spots near my hairline are also filling in.
