I started seeing results with the brow serum at about 9 or 10 weeks. Some of the hairs are dark, and some are grey. I am using less brow product (pencil, brow gel) now. The reason for only 4 stars is because the tubes only last me for 4 weeks, not 6 to 8. Hopefully they will last longer with the new brush design. Also, the before and after photos on the website are a little bit confusing. Some are labeled. Some aren't. They need to be more clearly grouped together in categories: Brows, Eyelashes, Skin, Hair etc.

Have been using for 8 weeks and see promising results.

I can't say enough about how well the lash and brow serum works. My lashes are longer and I actually have eyebrows
now. A little goes a long way with these products.

I’ve tried many different products to stop excess hair loss & restore hair growth, and unlike the rest, much to my delight this one actually has started showing results. I am one who needed a longer time to start seeing results but hung in there and did after about 10 weeks. Two bottles lasted me about 4 months, so although the price may seem high, the value was well worth it to me. I also am using the brow gel and seeing growth there too, unlike every other product I wasted money on in the past. This is the real deal!

Rarely, do I find something that delivers more than I anticipated. The Nulastin brow and lash serum--amazing. My brows were so light and sparse--I'm 57--no way I could be made up without brow powder--NO MORE! Of course, the lashes are awesome. I tell everyone about this--never thought I'd see the day.

I’ve always had thick eyebrows, until recently, where I developed bald spots within my eyebrows, especially near the bridge of my nose. Aging I guess. After using nulastin for about a month my eyebrows are thicker than ever. I am having to trim again which is a great sign and no longer need to pencil in the bald areas. This stuff works. I am on my third order of the product.
