Not another wash-day product

A focused step between washes.

Vitality 11 conditions the crown and fragile strands before cleansing. STIM-Foll serves a different role: it stays on the scalp between wash days to support a hydrated, cared-for scalp environment and the appearance of fuller, denser hair in targeted areas.

The formulas are complementary, but more is not always better. Introduce STIM-Foll gradually, follow the label, and adjust frequency if your scalp shows signs of irritation.

The multi-peptide architecture

Targeted actives. One intentional leave-on formula.

Each ingredient group earns a distinct place in the cosmetic scalp-support ritual. Explore the benefits of each ingredient group below.

The current formula data also identifies glycerin, propylene glycol, butylene glycol, disodium EDTA, polysorbate 20, phenoxyethanol and ethylhexylglycerin, citric acid, and vitamin E for hydration, delivery, preservation, stability, and formula performance. Final package INCI order remains subject to the corrected manufacturer master formula.

Visible density support

3% Redensyl®

Ingredient-level research suggests Redensyl® may support pathways associated with fuller-, denser-looking hair when used consistently.

Multi-active peptide complex

Procapil®

Research on this cosmetic complex suggests support for stronger-, healthier-looking hair and the appearance of improved density.

Peptide + red clover complex

Capixyl™

Research suggests its acetyl tetrapeptide-3 and red clover pairing may support the appearance of fuller hair in thinning-prone areas.

Pea sprout extract

AnaGain™

Ingredient research suggests this botanical active may help support fuller-looking hair as part of a consistent scalp-care routine.

Copper peptide system

AHK-Cu + GHK-Cu

These advanced cosmetic peptides help condition the scalp and complement the formula’s healthy-hair appearance focus.

Botanical scalp care

Saw Palmetto

Serenoa serrulata fruit extract adds naturally derived botanical support for a conditioned, cared-for scalp.

Botanical scalp conditioning

Black Seed Oil

Nigella sativa oil provides emollient, antioxidant-rich botanical care that helps condition the scalp.

Moisture and scalp conditioning

Niacinamide + hydration complex

Research suggests topical niacinamide can support the skin’s moisture barrier. In STIM-Foll, it complements sodium hyaluronate, panthenol, beta-glucan, and ectoin in our focus on a hydrated, conditioned scalp.

How to use

Consistency is the active ritual.

Use on a clean, intact scalp and focus on the areas you want to monitor most closely.

  1. Part the hair.Expose thinning-prone areas so the serum reaches the scalp rather than coating the hair.
  2. Apply directly.Use once daily or at least 4–5 times per week, following the current product label.
  3. Massage gently.Use fingertips for 1–2 minutes. Do not scratch or aggressively rub the scalp.
  4. Leave it in.Do not rinse. Allow the serum to remain on the scalp between washes.
  5. Track 90 days.Photograph the same areas in consistent lighting and assess scalp comfort, appearance, and routine adherence.

Use thoughtfully

Respect the scalp barrier.

For external use only. Do not apply to broken, irritated, infected, or inflamed scalp skin. Avoid contact with eyes. Stop use if persistent irritation occurs. Keep out of reach of children.

If you use a microneedling device, seek qualified professional guidance about appropriate timing before applying topical products. Do not apply STIM-Foll immediately after an invasive scalp treatment unless specifically directed by a qualified professional.

Two targeted roles • one coordinated ritual

Vitality 11 vs. STIM-Foll: What’s the Difference?

Understand where each formula belongs, how to use them together, and when to seek professional guidance.

What is the difference between Vitality 11 and STIM-Foll?

Vitality 11 is a concentrated botanical pre-wash scalp-and-strand treatment used 2–3 times weekly before cleansing. It conditions fragile lengths, helps reduce visible breakage and breakage-related shedding, and supports improved length retention. STIM-Foll is a lightweight leave-on botanical-and-peptide scalp serum used between washes. Its 3% Redensyl®, Procapil®, Capixyl™, AnaGain™, copper peptides, caffeine, and niacinamide provide targeted cosmetic support for thinning-prone and lower-density areas.

How do Vitality 11 and STIM-Foll work together?

They perform complementary roles at different points in the routine. Vitality 11 prepares and conditions the scalp and vulnerable strands before wash day. STIM-Foll remains on the scalp between washes to support a hydrated scalp environment and the appearance of fuller, denser hair in targeted areas. Together, they coordinate scalp conditioning, strand protection, length retention, and fuller, healthier-looking hair with consistent use.

How should I use them in the same routine?

Use Vitality 11 the night before wash day. Massage it into the scalp for five minutes, pull it through the mid-lengths and ends, and leave it on overnight or for at least two hours. Shampoo and condition on wash day. Once the scalp is clean and dry, apply STIM-Foll directly to the areas you want to monitor and leave it in. Continue STIM-Foll between washes according to its label.

Do I need both products?

Not necessarily. Choose Vitality 11 for intensive pre-wash conditioning, visible-breakage support, and improved length retention. Choose STIM-Foll for a lightweight, targeted leave-on peptide routine focused on thinning-prone or lower-density areas. Use both when you want coordinated support before cleansing and between wash days.

Can Vitality 11 or STIM-Foll stop or cure hair loss?

No cosmetic product can diagnose, treat, cure, or prevent a medical hair-loss condition. Vitality 11 and STIM-Foll support scalp care, breakage-conscious handling, and stronger, fuller, healthier-looking hair. Sudden, severe, patchy, painful, or unexplained hair loss should be evaluated by a qualified healthcare professional or dermatologist.

Can I apply STIM-Foll immediately after microneedling?

Do not apply STIM-Foll immediately after microneedling or to broken, irritated, infected, or inflamed scalp skin unless a qualified professional specifically directs you to do so. Allow the scalp barrier to recover and follow appropriate professional aftercare guidance.
