I was very skeptical that this serum would live up to the promise of fuller brows but it far surpassed my expectations. My brows have always been sparse and when menopause made its way into my life, my brows became almost nonexistent. Decided to give Nulastin a try and within a short amount of time my brows started to thicken as well as darken which was a very pleasant surprise. I will never be without this product.

I’ve never had thick lashes or brows and age hasn’t done them any favors either so I was SO excited to try the lash and brow combo. The lash serum worked amazing and I had great results after a month or so but it caused pretty bad dry eyes. After doing some research, I decided my eye health wasn’t worth it so I returned the lash serum. I was sad but the 100% money back guarantee is real and was honored! However, I kept using the brow serum and have to say this is something I don’t see myself ever going without. I started using it twice a day for the first 3 months but now sometimes only use it daily and still see results. It’s pricey but really effective and each tube lasts roughly 3-4 months so I think it’s well worth the money if you buy the 2-pack on sale.

Due to my slow thyroid, I lost a lot of my brow hair. I read the reviews and with the $ back guarantee, I thought, "What do I have to lose?" WOW! This really works. I have 2x as much brow hair as I ever did, before the medical issues. This works, full stop.

My most recent order at full price was disappointing in that it felt dry in the first week or so. Customer service was very nice but gave me an explanation instead of a replacement order. It really does work though.

One of my brows is not as full as the other. After using Nulastin, I am seeing a difference.

Wow! At 68 I literally had very light and almost non-existent eyebrows which made me look MUCH older than I felt. While skeptical, I tried Nulastin for my eyebrows and they are now at least as dark and full as in my twenties. I now have something to tweeze into shape and can get by with just mascara and lipstick. I saw results within the first month and will definitely continue to use the product. Five stars!
