Finally! Something that works!

I’m 50 years old and have been experiencing gradual hair loss for over a decade. This is the first time I’ve found a product that actually works!! My eyelashes are now thicker and even long enough that they sometimes brush the inside of my close fitting glasses…what a problem to have!!! No makeup needed here…

Literally amazing

I have issues with my glasses now because my lashes touch them!! They are so thick and long getting so many compliments!!

Long at Lash

I love the LASH Follicle Fortifying Serum and it works 100% I’ve turned other people onto it and they absolutely love it also. Nothing but Love for the Nulastin products!

Literally works!!!!

I had lost almost all my eyelashes from doing fake lashes for so long. When I stopped I was horrified at how little was left for my natural eyelash’s. I took a chance on hoped this product would work. It took till my second tube to really see the change. If I don’t
keep up in using it of course my lashes get sparse again so I always keep buying. It’s well worth it!


Wish I had taken before and after pics! I am so impressed! My lashes are amazing. Noticeably longer and thicker. I get comments almost daily.

Amazing Lashes

I’m very pleased with the results of the eyelash serum. It did take 6 or so weeks to notice an improvement in the length and fullness of the lashes, but what a great result. I’m not a young person (71) but it really worked well for me with no stinging side effects or anything. I passed a tube along to my daughter and she has been using it for about 3 weeks. I told her to keep it up and hopefully she will be as happy and amazed with the results as I have been. The only complaint I have, if you can call it that, is I have to remember to wife off the bit of mascara that sticks to the area under my eyebrows, since my lashes are so long where the mascara touches. The brow serum didn’t work for me I think because I barely have any brow hair due to my age, so there’s nothing to thicken.
