    Frequently Asked Questions

    Most of our customers receive their first unsolicited compliments within a few weeks of using NULASTIN. It should be noted that results may differ from person to person and not everyone will have the same response to the product. The speed with which you notice results is dependent on several factors such as the consistency of product application, age, gender, genetic predisposition, environmental conditions and other factors.

    With the LASH Follicle Fortifying Serum, you may start noticing some changes within a few weeks of using it. Your lashes may feel more luxurious, and they may hold mascara better. After six weeks of consistent use, you may observe even more significant changes, such as an increase in length, width, and density of your lashes. According to a clinical study completed in July 2023, the results of using the serum doubled between week 6 and week 12.

    With all of our products, timing is different for everyone. Your lashes, brows, and hair grow in stages. For lashes and brows, the cycle lasts 3-4 months. Scalp hair can take longer. 

    — The 1st stage (anagen)

    When your hair grows a little every day (30-45 days).

    — The 2nd stage (catagen)

    The transition or regression phase — when your hair follicles shrink, allowing the strands (bulb) to extend toward the surface (2-3 weeks). 

    — The 3rd stage (telogen)

    The resting phase. Your hair bulb is inactive, and the hairs eventually fall out (Around 100 days). 

    — The 4th stage (late telogen or exogen)

    Reassembly. This is where new follicles are formed. Think of it as the reawakening process before the hair starts back into the growth phase.

    All products are designed in Boulder, CO.

    All our products are designed for ease of use and can be applied under makeup with little or no wait time. For best results, use twice daily to clean, dry eyes and/or skin.

    My brows are back!

    I received my Nulastin Brow Serum at the beginning of March. Within a few weeks, I noticed my brows looking fuller and darker than before. Now, two months later, my brows are back and better than before. Growth has been incredible and my 60 year old thinning and graying brows look as good as they did in my 20's!


    This stuff really works!! My lashes are so full and long now! I don't even wear mascara because I don't need to. I will continue using Nulastin because the results are so good!

    Amazing Results!

    I have been using NULASTIN brow and lash serums consistently for about six months. I am blonde with very fine hair. Before starting NULASTIN, my lashes were super short and my brows were very light and sparse. I have seen significant improvement after using the serums. My brows have darkened and I have recently noticed new growth. My lashes are spectacular! They are so long, they touch my eyeglasses! I don’t really even need mascara. I was considering getting false lashes but so glad I don’t need them now! The only thing I regret is not taking my “before” photo!

    I started using the lash serum at the same time as using the brow serum, I have great results for both my brows and lashes. Couldn’t be any happier, when I look in the mirror I love how my brows and lashes make me feel and look younger! They look like they did in my 20’s, 30’s, 40’s and 50’s, then menopause happened and they disappeared! They are back!!!!

    Big change in just 9 weeks!

    I notice length most but also see some thickness improved. Sometimes I feel a bit of stinging/burning after application but it resolves in just a few minutes.

    Absolutely worthy

    My lashes are visibly longer and thicker after 2 months of using this product.
    The first photo shows my lashes with 3 layers of mascara, and the second picture shows my lashes visibly longer and thicker without any máscaras on them.
