No change after using product
So far, this product has not worked for me. I had been using for a little over a month, twice daily, with no change in eyebrows. Perhaps the reason for thinning brows affects whether the product works

Hi Marnie! With consistent, twice-daily use, most people see results in 6–12 weeks. Stick with it—long-term consistency delivers the best results!

No noticeable brow regrowth yet
I've been using the brow serum 2x a day for 6 weeks now and half of my brows are still missing. It may not work for me - disappointed!
NULASTIN response
Hi Arg! Thank you for leaving us an honest review! It does typically take 6-12 weeks to see noticeable results when applying twice daily.

made existing brows darker &fuller
My experience, the outer edges of my eyebrows are barely there due to thyroid. At 6 weeks It definitely made the areas where I have brows thicker, and not so much where there were are sparse brows. Some growth, but not as much as I would hope for also, I didn’t understand this would happen. It made my brows much darker than they normally are. To the point where I use a blonde brow mascara to make it look more natural for my complexion and hair color I think if you have just general thin browse, this will work for you. I’m not sure that it will regrow where your brows have kind of disappeared. Also, the first tube went bone dry a week before my refill was due. I used the refill frequency suggested on the website. That’s my experience.
NULASTIN response
Hi Macie! Thank you for sharing your experience. It generally takes 6-12 weeks of twice daily use to see maximum results. Additionally, if darker brows are not something that you find desirable, we would recommend to use less serum or back off to applying 3x per week. As for the tube running out of serum, as long as it lasted a minimum of 4 weeks, it was filled to capacity. Each tube is designed to last 4-6 weeks when applying twice daily. It really just depends on each users application practices.

A fix for aging /thinning brows
My eyebrows were thinning and getting lighter with age. Nulastin helped regrow my brows and gave me a more youthful appearance. So happy with the results!

fuller, darker brows
At first I was using the brow serum twice daily and due to red rashiness I was told by Nulastin to try every other day and once daily. Once I started that routine everything was great. Within a few weeks my eye brows came in beautifully; they were fuller and darker than I've seen in the last 20 years. It's been really wonderful seeing these results. This brow serum works !!

It seriously works!
Never imagined this would really work- Wow! I’ve been faithfully using the brow serum for a year or so and over time I realized I’m using very little brow pencil to fill in. Another shocker was that the individual hairs grow SO LONG and don’t fall out that I’ve had to comb my brows down like bangs (fringe) and trim them shorter! Never in my life was that happening, even in my younger years! (I’m close to 64 with fine blonde hair.) I was so impressed that I started using their scalp/hair products as well! This serum is worth every penny!
