"My brows are thicker and longer than EVER."

BROW 2-PACK Shape Altering Serum with Keracyte® Elastin Complex
Clinically Proven For 120% Fuller, Thicker Brows
If you have sparse, thin brows or are dealing with hair loss from aging and/or hormonal conditions, our scientifically proven BROW Shape Altering Serum with Keracyte® Elastin Complex and Elastaplex™ Technology can visibly boost the look of healthy, natural, full eyebrows — regardless of your age, gender, or health.
In a 12-week clinical evaluation, our BROW Shape Altering Serum increased the density and thickness of participants’ eyebrows up to 120%.
Made with skin-safe, naturally sourced, naturally derived ingredients and backed by 5 issued U.S. patents, our groundbreaking formula works stimulate degraded hair follicles by strengthening hair-producing cells — attracting new hair-producing cells. By building back the body's elastin supply with patented proteins, active peptides, and powerful antioxidants, our unique brow treatment helps protect against visible thinning and encourages the appearance of perfectly shaped brows.
When used as directed (twice daily — morning & evening) each tube should last approximately 6 weeks. Once you achieve your ideal look, you can reduce application to once per day, or 3-4 times per week — which will make the product last much longer.

Reviews
As a 20 something in the 1990s my sparse brows were a product of the over plucking era. I was nearly missing the last 1/3 of the brows and the rest was getting sparser by the decade. I tried Nulastin only because of the money back guarantee. It actually works! I am thrilled and even had to find my tweezers which I hadn’t used in 15 years.
Going on week 6 of using the brow and lash serum. My brows are thicker and filling in with new growth. I’ve tried other products and this is the first to show real improvement on my eyebrows! And I was skeptical when I ordered. I will definitely continue using this.
Lashes are doing pretty good too.
I have tried at least a half dozen other brow enhancers...Nualstin actually works. I have had thinning brows since menopause and I thought this was it. Nualstin has thickened existing brows and created new growth in sparse areas. The price is high but the results are well worth it!
I have had brow issues for a long time - sparseness and gray. I tint them for the gray but Nulastin has made them much thicker - the girl that tints my brows could not believe how much thicker they were - in on month!
As I am getting older, my eyebrows have gotten thinner and thinner. I have been using this once a day for the past 6 weeks and I am amazed. The brows have filled back in and look fabulous!
Like a lot of people, I overplucked and overwaxed in the late nineties/early aughts. I discovered microblading around 2009 and have had it done 3 times since. So with all of that trauma, I just assumed nothing would ever grow in (seriously, I rarely ever had even a single new hair come in around my brows). I've been using Nulastin for just short of 2 months, and right now the new growth is sort of wild, but at this rate I might actually have full brows again within a couple more months! Honestly can't believe I've wasted so much money on microblading!
