It works better than other serums

I was using Grande Brow before using this serum and I have to say, I saw significantly more results with the Nulastin serum. I have hairs growing in from over-plucking that I haven't seen in over ten years. I can actually leave the house without filling in my eyebrows and the shape is so much better.

working well for me!

My brows were decent before using the product, but thinning somewhat due to age. I used the brow serum for about 4 weeks, twice daily as instructed, but have since been able to cut it down to three times per week because my brows responded so well to the product. It's been four months so far and still so good.

I have brows again!

Nulastin brow serum works! I use it morning and night and my brows have really filled in. They are measurably thicker than before. The only down side is that some of the hairs are coming in gray and I now have to dye my brows. The hazards of aging!

works well on existing eyebrow hair. please put all serums in clear tubes!

i have bought brow serum several times and it definitely works on my existing brow hairs; they are thicker and longer! i am 60 and have not seen much “new growth” in my sparse areas. please put all serums in clear bottles…bought it on amazon and the clear bottle makes so much sense!

Nulastin works!

Within two months, I noticed that I could actually see eyebrows! I didn’t say anything about it to anyone, hoping someone would notice and say something, unsolicited. Not one word from anyone. I decided to take a chance … and mentioned to my son that I’d been using Nulastin and to my eyes I could see eyebrows. Lo and behold, he agreed! He said he hadn’t said anything because he thought maybe he was seeing things. Ha ha. I was so happy. It’s now been 3 months using Nulastin and I have eyebrow growth and I am amazed and overjoyed. I love it and am so thankful. I’ll have to take an after-photo to share.
