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.


Finally!! A product that blows apart the old expression "If something seems to good to be true, it probably is". Seriously, this product absolutely does what it claims it will do! I purchased the Eyebrow and Eyelash duo and began using the Eyebrow serum 3 months ago, deciding to try it first before opening the Eyelash serum (I haven't used it yet). Within a couple of weeks, my thinning eyebrows were thicker, longer, and darker. When I had my first eyebrow styling appointment since beginning to use the Eyebrow serum, my stylist was amazed! She's been waxing my eyebrows every other month for about a year and she said this is the first time she's been able to create an actual arch shape because she had so much more eyebrow hair to work with! Per the directions, I started out using the Eyebrow serum twice a day. Because I had such excellent results, I'm now using it only at night as a part of my skin care routine. In my opinion, Nulastin is worth every penny I paid! Here's another old expression that actually does apply: "You get what you pay for."


Having no eye lashes (maybe 5 on each eye) 30+ years and barely any brow hairs 40+( I've always had more hair on the left and blond) I now have brows at 64 and the hair is darker! Not the tail end yet but new hairs sprouts are coming every day on both lash and brow. Lashes I had to take it slow, no after pictures yet. I've passed the 90 day mark. I've have thyroid issues since my 20's. Over the years I got very good with my makeup to hide the missing lashes and brows.. Stick with it! This product truly, truly works. I no longer dread waking in the morning to quickly put on my 'brows'.. Eye lash pics will come soon.. Thank you Leah. This really has changed my life.

Expensive, but works

I have been buying cheaper products for my thinning eyebrows over the internet for about a year, with pretty much no results. I bought Nulastin about 3 months ago for my thinning eyebrows, and it is super wonderful! My brows started showing results about a month ago, and even I had to trim them! (For my daughter’s wedding) They are darker and fuller. Even growing where I don’t really want them, but I’m not complaining. Tweezers are back in my life! THe product is expensive, but no doubt it works. Don’t waste your money on other products like I did.

Full and thick eyelashes and brows

My eyebrows and eyelashes are lovely, full and thick. I thought this would never happen due to a hypothyroid condition. After diligent use to, I look forward to shaping, tinting and keeping up with the full brow trend. Bonus… no irritation or side effects despite sensitive skin and eyes.

Seeing regrowth!

I have been using the brow serum for 4 weeks and already seeing some regrowth!! Very exciting!
