    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.

    The BROW Shape Altering Serum and HAIR Vibrant Scalp Treatment may take more time, but clinical studies show a 60% improvement in brow thickness/size and a 50% improvement in hair thickness by week 12!  To achieve the best results, it is recommended to apply the product in areas where there is less hair, twice a day (morning and night). However, some areas may take longer, up to six months or more, to improve. Unfortunately, if the hair follicle is damaged beyond repair, new growth may not be possible.

    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!

    Finally, eyebrows!

    This brow serum is absolutely amazing! I barely had eyebrows since going through chemo and radiation treatments 8 years ago. After using Nulastin brow serum for about 6 weeks my eyebrows are full and lush again! Seriously, I had my doubts when trying it, but it worked! I can’t even tell you how thrilled I am!

    It really works!!

    I’m so happy with my Nulastin! With age, and thyroid issues, my eyebrows had thinned drastically. I wasn’t happy with any of the brow powders or pencils. By my second tube of Nulastin, I can see new growth all along my brows. (Too bad it’s coming in gray, but hair dye will fix that!). For the first time in my life, I’m going to have to have my hairdresser actually trim my eyebrows because they’re starting to look bushy! Thanks, Nulastin, you’re a miracle!

    Worked better than I expected

    I have always had very sparse, blonde eyebrows. Plus, years of over tweezing to try to give them definition did nothing to help. For the first 6 weeks or so of faithfully applying Nulastin, I didn’t notice any change. Then BAM. My eyebrows literally doubled in volume and got dark. Everyone asks me what in the world happened. I’m trying to get used to having eyebrows. But I’m very happy with this product

    It’s working!

    I was pretty hesitant to try this product due to the cost, but the reviews were glowing, and there is money back guarantee, so I decided to try it. It’s been 6 weeks, and my eyebrows are definitely fuller. I over tweezed my right eyebrow more than the left because it grows differently, and this is the one I’m specifically watching. I still use a small amount of eyebrow pencil in that brow, but I’m hoping I won’t have to if I keep using this product. Definitely worth trying!
