Frequently Asked Questions

A majority of our customers get their first unsolicited compliments after a few short weeks of using NULASTIN®. Results vary from individual to individual and not everyone will respond the same way. How quickly you notice results depends on factors like gender, age, genetic predisposition, environmental conditions and more. 

With the LASH Follicle Fortifying Serum, you may notice changes within weeks. Lashes might feel more luxurious and hold mascara better. Within a month, overall changes may be even more noticeable, including the appearance of length, width, and density. 

The BROW Shape Altering Serum and HAIR Vibrant Scalp Treatment may take more time, but stay the course! The best practice is to apply the product in the areas where hair is sparse two times per day (morning and night). Certain spots can be problematic and may take six months or longer to improve. In cases where the follicle is damaged beyond repair, you may never see new growth. 

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.

We are proudly 100% made in the USA. As a Boulder, Colorado company, we also take pride in the fact that we manufacture and endeavor to source locally. Our workforce supports American jobs within the community.
