This Stuff Works!

As a result of some bad tweezing decisions in the nineties, I had a half eyebrow on my left side. Think Mr Spock. I’d tried other products to make it grow in and nothing worked so I’d resigned myself to drawing the other half of my eyebrow every day. I saw the ads for Nulastin with the before and after pictures and I decided to give it a try. Now, it doesn’t work overnight but in about 12 weeks my eyebrows were thick and completely grown in. I then went to a brow tech and she tweezed my brows into beautiful arches. Success! No more Mr. Spock and I can put away my brow pencil!

So surprised!

Wasn’t really expecting to see results on my right eyebrow. I fell last year and had a gash across my right eyebrow, requiring stitches. That leaves scar tissue. But I am seeing hair growth in the scar area! I am impressed.

Great After Medical Treatment

I had a pre-cancer area of my eye brow treated with cryotherapy (doctor applies liquid nitrogen to freeze and kill the cells) several times over several months. It also caused a lot of hair loss in the area. After treatment I started using the brow serum to try to regrow my eyebrow. I was amazed at how quickly and effectively it worked! I love this product and am now a user for life!

Very scepticle about the product but kind of desperate to find something to help my thinning eyebrows. Started using the product in September of 2023, and it works! I’m 68 and my eyebrows have never been this dark and full. Such a believer.
