This product is amazing! After only 3 weeks I began to see results. Brows are darker and definitely thicker.

Thyroid issues

Due to a nonfunctioning thyroid my brows were embarrassingly sparse. I bought nulastin and started using it. It took about a month before I noticed a difference. The first bottle lasted about 2 months. My brows are filled in!! Starting my 2nd bottle and using it 1x every day. I’d love it to be less expensive yet it is worth it to me.

Good product

Had eyebrows tattooed for convenience, with discoloration after I did not like. Nulastin helped even out color along with new growth of brow. Looks so much better. Thank you!

It’s true!!

Been using both the lash and brow serums since April and super happy with results. 6 weeks is when I noticed some of my lashes were longer but a little uneven. At about 10 weeks is when they were all long at same length. I also noticed a huge difference in the thickness of my lashes and they were a little darker. You could see and feel it. I wear contacts and my eyes are sensitive. I used Latisse in the past and had nothing but problems. Nulastin has not irritated my eyes at all. My brows are fuller and strands thicker. Very happy with the results and highly recommend it!!

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.
