  • The more, the merrier!
Size: 0.17 Fl Oz (Pack of 1)
I wanted to use this to help my hair grow and I think for the growing part it was wonderful. But I was hoping it would help re-grow some of the bald spots I had. However my hair just got longer and that helped cover the spot but it did not regrow in that spot. I’ve cut my eyebrows down and grown them a couple of times. So it makes you wonder if it’s the product or just you leaving them alone. One thing for sure is I grew hair below the eye.. which I’ve never had before but maybe because the capillaries connect and me placing it in the eyebrow it was received in the wrong place. Anyways I still recommend the product. It did its job one way or another. See the before and after one photo taken June 17th and the other August 13th. Also the hair below the eye. Enjoy! Happy eyebrow regrowing! ... show more

  • The best eyebrow product I have ever used
Size: 0.17 Fl Oz (Pack of 1)
This stuff is insane! I wish I tried it years ago before I had any cosmetic tattooing done. I always had thick eyebrows that have grown patchy over the years. I decided to try this instead of a tattoo touch up. I cannot believe how well it worked and very quickly. It made my brows thick and dark, and I cannot even see the tattooing that was done anymore. I highly recommend this product! Just be careful. I sometimes put it on my lashes too. When I sleep, I guess a little bit migrates onto my upper cheeks, just under my eyes. This caused the tiny peach fuzz to get dark lol. So I have to remove it now with a trimmer. Still definitely worth it! I don’t even have to use an eyebrow pencil anymore. ... show more

  • Worth it
Size: 0.17 Fl Oz (Pack of 1)
I’ve been using the Obagi Nu-Cil Eyebrow Boosting Serum for about 2 months now and I can confidently say it works. Yes it’s expensive. That was my biggest hesitation. But the results came in faster than I expected. I had sparse, slightly over tweezed areas and I’m seeing real growth and better fill-in, especially in patchy spots. What surprised me most is how long it lasts. The bottle feels light when you first get it, but a little truly goes a long way. I use a very small amount daily and it’s still going strong after months. The formula is lightweight, absorbs quickly, and doesn’t feel heavy or greasy. If you’re on the fence because of the price it’s definitely an investment, but in my experience it’s been effective and worth it. ... show more

  • DO NOT WASTE YOUR MONEY – PRODUCT DOES NOT WORK, AMAZON REFUSES TO HELP
Size: 0.17 Fl Oz (Pack of 1)
DO NOT BUY THIS PRODUCT. I used the serum consistently as directed and saw absolutely no results. It is advertised as lasting 3 months and delivering visible results, but it did not deliver what was promised. Even worse, Amazon refused to help. Their only response was that the return window had expired. They did not care that the product does not work as advertised. Once they have your money, apparently the customer is on their own. Very disappointing product and extremely disappointing customer service. I would not recommend it to anyone. ... show more

  • THIS STUFF WORKS
Size: 0.17 Fl Oz (Pack of 1)
I have used so many different serums to help with my senior citizen eye brow. Yes, only one of them. I overplucked it and it has never grown back. I have tried Nulastin several times, Grande Brow, the cheap stuff from Target, and NONE of them EVER worked. I gave the Nulastin several purchase attempts also. THIS IS THE REAL DEAL!!! Before one serum is gone, I have new brows!!!! CRAZY!!! It is so easy to use. One swipe at night. I would def say this is so worth the money as it actually works!! ... show more

  • Totally made a difference!!
Size: 0.17 Fl Oz (Pack of 1)
I don’t know how it works but this product totally made a difference with my eyebrows!! I’ve been using it now for four months now and just started my second tube. I noticed changes after two months. My eyebrows were thinning as I’m getting older, also I probably over plucked them when younger and I was considering tattooing but read about this product and decided to give it a try. It is expensive but the first tube lasted 3+ months so I feel its it’s worth every penny for the results. No more, eyebrow pencil and my eyebrows are thick and dark like they were when I was younger. Try it, you have nothing to lose! ... show more

  • The best eyebrow regrowth/growth product ever!!!
Size: 0.17 Fl Oz (Pack of 1)
Expensive but worth it!!! I’ve tried everything for eyebrow growth (Vegamour, the ordinary, multiple things in Amazon, home remedy/oils) and this is the only thing with actual results- and quickly. I use it every night and noticed eyebrow growth within a couple weeks. I have super super sensitive skin and this does not agitate at all! So impressed. Worth the hype. 10/10 I do not spend much on skincare - I usually stick to all vanicream products but this is worth the splurge!!! ... show more

  • IT WORKS!
Size: 0.17 Fl Oz (Pack of 1)
I have always struggled with sparse brows and after struggling to grow them back after a botched wax years ago I’m so happy to say I’m finally seeing new growth! Im giving 4 stars solely for the price. It is ridiculous for the amount of product you get.. one tube is supposed to last the 12 weeks it takes to see results but it completely runs out around the 8 week mark. My first pictures are the before, the after, then cleaned up the darkness is completely from the product only I didn’t tint at all. My brow still has a little bit to go but I think by the end of the year I’ll have the brows I’ve dreamed of. ... show more
