Due to thyroid problem - my eyebrows where thinning
Especially on my left eyebrow -I lost ALL the hairs from the arch on. Leah advised me to apply the serum twice a day - due to work schedule I only applied once - and used my eyebrow pencil as usual - once the serum dried it act as a base... two months later The HAIRS GREW BACK!
I had used Dr prescribed Latisse that was more expensive and did not work as well ( Dr. prescribed for eyelashes - told me can be used for eyebrows)
Nulastin is natural - it's true - and will not disappoint you - the Company stands by their product!
I have been using Nulastin for several months now and my skin and I love it! My face feels hydrated and refreshed, the elasticity improved and this sensitive red head is pleasantly not allergic! Go Nulastin!
Answer: The serum should not stop working and there is no evidence clinically that would suggest individuals become immune to the formula. However, because our biology is unique and our systems are constantly going through phases of growth and repair, stress and life, we have noticed that there are seasons when visible changes like less robust growth occurs. Our Founder and CEO, Leah Garcia has been a go-to for understanding the ebb and flow of results. For example, she too experienced a time-period after using the serum for over two years when her lashes were just not responding as magnificently. She stopped using the formula for 30 or so days and then, re-introduced it. Her lashes not only kicked into another natural growth-spurt, they came in luxuriously feathery and symmetrical. We don't have a definitive timeline on how long to rest, and there is nothing scientific about this troubleshooting tip. It's just a bit of real world creativity.
Answer: Hi Beth, great question. Our BROW serum is fragrance free, so no need to worry! If you have any additional questions feel free to email us at [email protected].
Answer: You should continue using the product as an ongoing part of your daily routine. If you discontinue use, your skin, lashes, brows, and hair will gradually revert back to their original appearance. The good news is that you can decrease usage after you've achieved a desired look. For LASH, BROW, and HAIR products: Once you reach a point of satisfaction, you can apply the serum once per day. Another option is to decrease application to three or four times per week. When you want to increase the results again, go back to using twice per day.

Answer: Thank you for reaching out and sharing your concern. First off, we would like to thank you for being a loyal customer. The serum should not stop working and there is no evidence clinically that would suggest individuals become immune to the formula.

We recommend keeping the unused serum in the refrigerator until you are ready to use it again, so the DNA proteins maintain their full potential. Please keep us posted on your progress.
Answer: We have heard from many customers with hypothyroidism. Many of them have seen great success while using NULASTIN. There is an intimate connection between the hair follicles and the extracellular matrix that supports the follicles in the skin. Not only is elastin and its precursor, Elastatropin® (our exclusive DNA protein), synthesized by the cells in the hair follicles, but the follicles themselves appear to depend on elastin and the structure of its matrix for their function and vitality. NULASTIN nurtures the cells that produce hair follicles. Our formula has five active ingredients - all designed to deliver positive results. That said, everyone is different. What we can not predict is how you will respond to NULASTIN's follicle fortifying serum.
Answer: We have products for the LASH, BROW, SKIN and HAIR. You can find all of our products on our website!
Answer: Regarding the prevention of male pattern baldness, we are confident that addressing the health of the hair follicles in the scalp, specifically the elastin and Keratin proteins will improve the vitality of the hair. But in all honestly, if male pattern baldness has already damaged the follicles beyond repair, there is no treatment that can bring dead hair back to life. That being said, if there is life in the follicle - no matter how dormant it may be, we believe that we can help! Certain spots can be problematic and may take six months or longer to look better.
Answer: Your brows, lashes, and hair will stay thick through their natural growth cycle, then they will return to their regular state when you stop using the serum. The good news, is that you can back off after you achieve a desired look. Once you reach a point of satisfaction, you can apply the serum 1x per day. Another option is to decrease application to three or four times per week. When you want to pump up the results again, go back to 2x per day use.
