How to Use the LASH Follicle Fortifying Serum

Start with clean, dry eyelids.
Using the applicator, apply a thin line of serum along the base of the upper lash line, from the inner to the outer corner.
Apply twice daily – morning and evening – after skincare and before makeup.We do not recommend applying to the lower lash line, as this may increase the risk of irritation near the eye.

Application Tips
If you have sensitive eyes, begin with once-daily use (AM) to allow your skin to adjust.Some users prefer to keep eyes closed for a few seconds after applying. Fanning the area can help the serum dry quickly.
The serum can be used under makeup with minimal wait time.
Avoid using the serum over mascara, as this can contaminate the applicator.

Consistency Matters
For best results, use consistently as part of your daily routine.
Store in a cool, dry place, away from direct sunlight and heat.
Do not freeze.
Avoid direct contact with eyes. If contact occurs, rinse thoroughly with cool water.

How to Use the BROW Shape Altering Serum

Begin with clean, dry eyebrows.
Using the applicator, apply the serum in short, upward strokes directly onto the brow area.
Apply twice daily – morning and evening – after skincare and before makeup.
Re-dip the applicator into the tube as needed for full coverage.
When using a new tube, gently shake the container before opening to activate flow.

Application Tips
The serum can be used under makeup with minimal wait time.
Avoid applying after brow pencils or gels, as this may contaminate the applicator.
The serum has a thick consistency by design to stay in place. You may notice some resistance when removing the brush—this is normal.
The vegan brush may feel firmer at first; after a few uses, the bristles will soften and absorb more product.

For Best Results
Use consistently as part of your daily routine.
Store in a cool, dry place, away from direct sunlight and heat.
Do not freeze.
Avoid direct contact with eyes. If contact occurs, rinse thoroughly with cool water.

How to Use the Vibrant Scalp Treatment

Start with dry or towel-dried hair. Avoid applying to soaking wet hair, as this may dilute the formula.
If applying after washing, use before leave-in conditioners or styling products.
If not post-wash, the treatment can be layered over existing product, as long as the scalp is accessible.
Apply 2–3 pumps of Vibrant Scalp Treatment directly to the scalp in areas where support is desired.
Using the Stimulating Scalp Scrubber, gently massage the product into the scalp—focusing on targeted areas first, then massaging through the entire scalp.
Use twice daily – morning and evening. No rinsing required.

Tips for Use
Clean or recently shampooed hair is not required—just ensure hair is not dripping wet prior to application.
Allow the formula to absorb for about a minute before layering other hair products or styling.
If product from earlier remains in your hair, it’s still safe to apply the treatment directly to the scalp.

For Best Results
Use consistently as part of your daily hair care routine.
Store in a cool, dry place, away from direct sunlight and heat.
Do not freeze.
Avoid contact with eyes. If contact occurs, rinse thoroughly with cool water.

How do I use the Vibrant Scalp Shampoo & Conditioner?
For optimal results, follow these simple steps:

Shampoo
Apply Vibrant Scalp Shampoo to wet hair, starting at the mid-lengths and ends, then working up to the scalp.
Massage gently to cleanse and stimulate.
Rinse thoroughly with cool water to help seal the cuticle and refresh the scalp.

Conditioner
Apply Vibrant Scalp Conditioner from the mid-lengths to the tips, then work up to the scalp.
Let it sit for a few minutes to allow the formula to nourish and soften the hair.
Rinse thoroughly with cool water.

Follow with Treatment
After towel-drying, apply the Vibrant Scalp Treatment directly to the scalp to complete your routine and support scalp health and fuller-looking hair.

How do I use the Vibrant Scalp Scrub?
For best results:

Wet hair thoroughly with warm water.
Apply the Vibrant Scalp Scrub directly to the scalp.
Massage gently to create a lather and achieve a deep, revitalizing scalp exfoliation.
Rinse thoroughly to remove buildup and impurities.
Follow with your Vibrant Scalp Shampoo and Conditioner.

Tip: Use twice weekly as a pre-cleanse treatment to help maintain a refreshed, balanced scalp.

NULASTIN® is the only cosmetic brand to feature Elastaplex® Technology, a proprietary blend of cruelty-free, bio-designed proteins, including vegan elastin and keratin, formulated to support the appearance of longer, stronger-looking hair, lashes, and brows. Our formulas are thoughtfully designed to complement the skin and scalp environment and support the natural look of hair density and fullness over time.

Unlike other products that may use animal by-products such as bovine-derived keratin, our elastin and keratin proteins are vegan, biodesigned, and bio-identical in structure to human proteins—created without the use of animal-derived ingredients.

Our LASH, BROW, and HAIR serums are suitable for most skin types and are made in small batches to maintain freshness and performance. Formulated in Boulder, Colorado, USA, we prioritize clean, high-performance ingredients and never test on animals.

Every NULASTIN® product is:

Dermatologist tested
Vegan & cruelty-free
Free from sulfates (SLS & SLES), parabens, formaldehydes, phthalates, talc, petrolatum, and mineral oil.
We are proud to offer performance-based, ethically sourced formulas that support the look of healthy, vibrant hair and skin—backed by our 100% Performance Guarantee.

When used as directed—twice daily, morning and evening—each NULASTIN® serum typically lasts 4 to 6 weeks. Individual usage may vary based on application technique and area of focus.

Once you've achieved your desired look, you may choose to reduce to once-daily use to help extend the life of the product. If you’d like to boost visible results again, you can return to twice-daily application.

Important: Do not exceed two applications per day. Our formulas are optimized for performance at the recommended usage. Using more than directed will not improve results.

Each LASH and BROW serum tube contains 3 mL of concentrated formula, designed for twice-daily use over approximately 4–6 weeks.

Exposure to light, heat, and air can degrade the quality and effectiveness of cosmetic serums over time. That’s why our HAIR and SKIN collections are packaged in opaque containers with airless pumps—to help preserve formula stability, freshness, and performance.

Each product is filled to maximum capacity and undergoes quality control by our FDA-registered, cGMP-, OTC-, and NSF-compliant manufacturing partner.

LASH & BROW Serums
Each applicator is designed to hold the recommended dose. Once removed from the tube, there’s no need to re-dip—one application delivers enough formula to treat both lash lines and both brows. If you choose to double-dip, that's up to you, but it may shorten the product's lifespan.

HAIR Vibrant Scalp Treatment
Use 2–3 pumps per application to cover targeted areas of the scalp. Applying more is safe but may cause the product to run out faster than the expected 4–6 week timeframe.

Reminder: All NULASTIN® formulas are designed for optimal performance at the recommended dose—more isn’t better, just faster.

All three formulas—LASH, BROW, and HAIR—share a powerful foundation of clinically evaluated, performance-based ingredients. However, each is carefully tailored for its specific application area:

LASH vs. BROW Serums

The LASH and BROW serums are formulated with the same core ingredients, but the BROW serum contains a slightly higher concentration of one active component. Brows generally benefit from a more concentrated formula, while the eye area is more delicate and requires a gentler approach. The LASH serum is designed for performance with sensitivity in mind.

LASH applicator: A precision eyeliner-style brush allows for a smooth, controlled application along the upper lash line, minimizing waste.

BROW applicator: A soft spoolie brush enables broad coverage with a single sweep. Gently massaging the serum into the brow line may help stimulate circulation and enhance the appearance of fuller brows.

HAIR Vibrant Scalp TreatmentThe HAIR serum features the same base technology found in the LASH and BROW serums, with the addition of two key ingredients to support scalp hydration and visible vitality:
Provitamin B5 (Panthenol): Helps maintain moisture and supports a healthy-looking scalp environment.Blackberry Leaf Extract: Known to support elastin-related pathways, this botanical ingredient complements the formula's focus on scalp renewal.

Each formula is thoughtfully designed for its specific area of use, with application tools and ingredient concentrations calibrated to maximize comfort, consistency, and visible results.

Thousands of customers with sensitive skin have used NULASTIN® without issue. While a few individuals have reached out with concerns, most have continued using the products successfully. That said, everyone’s skin is unique. If you have sensitivities, we recommend performing a patch test before full use to ensure compatibility.

Our proprietary formulas do not contain sunscreen. We recommend applying a broad-spectrum SPF from a trusted third-party brand after using NULASTIN® products as the final step in your daytime routine.

Vitamin C is widely recognized in dermatology for its ability to support skin brightness and help improve the appearance of photoaged skin. It’s also commonly used to visibly reduce uneven skin tone. However, it is a delicate ingredient—unstable and difficult to deliver effectively into the skin without compromising formulation integrity.

At NULASTIN®, our team is actively researching stable, high-performing forms of Vitamin C that meet our standards for efficacy and safety. Stay tuned—innovation is in progress.
