    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.

    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!

    Excellent results

    I’m 65 years old with Hashimoto’s Thyroiditis. Before trying Nulastin, my eyebrows were almost non-existent. In a matter of a few weeks after starting it, my eyebrows grew back in. I’ve never stopped using it since, and am thrilled with having eyebrows again!

    It’s working!

    I was skeptical. I tried another brand which did nothing, but I think this is working. Check out the photo. It’s been 6 weeks.

    Patience is the key

    I used the Nulastin brow shaper for over two months and did not see much change in growth or color. By the end month 3 and into month 4, my eyebrows suddenly became much darker and more prominent. On the good side, I do not need to use the colored brow gels and pencils as much to color in my brows. However, the areas that were thin toward the bridge of my nose are still a little thin. So, the hairs are not really filling in as much as they are just coloring the ones I already have. I am going to keep using it in hopes maybe those areas will start to fill in over time. I have already seen that patience pays off and sometimes our growth may take a little longer than others.

    First brown serum that has worked for me!!

    Gail O.

    I am confused about the size of the brow serum. I have ordered multiple times and the last tube is much bigger than the previous ones. However, the amount in both tubes is the same 0.1oz. 3ml. Can you explain how that can be?
