Eyebrows, finally

After a month of using twice per day, I have eyebrows once again. It works!

Gradual improvement

7 weeks in and I definitely see new growth in my brow area, but patience is in order :)
My existing brows have definitely darkened, but I'll need to continue to get a more filled-in look.
For reference, the first tube lasted 3 weeks for me; I was able to stretch the 2nd tube to 3.5 weeks... not sure how long they are supposed to last, but that was my experience.

Pleasantly surprised.

I started using Nulastin for my brows in May. I was very skeptical as I've not had luck with other serums. To my surprise, after 6 weeks, my bare spots were filling in. Now after almost 5 months, my brows are fuller and I don't have to fill in as much with an eyebrow product. Since I had good luck with the brow serum, I tried the lash serum. After only 8 weeks my lashes are fuller and longer than I ever thought possible! I'm a fan for sure.

Best product in the market

I was a Roden & Fields Lash Boost user for years, even though it really was not performing as well as I would have liked. I then saw Nulastin on Facebook and decided to try it.....I haven’t looked back. I’ve been using Nulastin for 9 months and I had my first brow wax ever.....EVER. If you buy one product, make it Nulastin. I’m telling you, this product is for real. Thanks for making me feel pretty again Leah. ❤️❤️❤️

No more penciling in my eyebrows

After a long bout with a health issue and chemotherapy, my hair was okay but I had NO left eyebrow and a few hairs on the other. Thanks to your wonderful product, I have normal eyebrows again.

It actually works

I was really skeptical and nervous about buying such an expensive product, but took a chance based on some of the before/after photos. My brows were overplucked in the past, and I had been trying to grow them back out for a couple of years. I had a persistent bald patch on one brow in particular. I started noticing new growth after just a few weeks of using Nulastin. After about 2 months of twice daily use, my brows have really started to fill in - even the bald patch. They do grown in much darker and longer, so be prepared for that. I had to use brow scissors for the first time in my life. This was definitely worth the money.
