Our science
We built the formula around the real cause.
Most hair gummies treat the symptom (a thin ponytail). Ruubyn® was built to address one of the most common upstream triggers in modern hair shedding: chronic stress and anxiety. Here's the thinking behind every milligram.
- Vegan
- Sugar-Free
- Non-GMO
- Made in USA
Three pillars
How stress turns into shedding — and what we did about it.
Hair shedding from stress is well-documented in dermatology as telogen effluvium. The science is settled enough to inform a formula, even when the conversation around supplements isn't.
-
01
Stress disrupts the hair cycle
Sustained cortisol elevation pushes hair follicles prematurely from their growing phase (anagen) into shedding (telogen). The result shows up 2–3 months after the stressful event — not during it. That delay is why so many women feel blindsided.
-
02
Adaptogens support the response
Standardized ashwagandha (Sensoril® / KSM-66®) has the largest body of evidence for supporting healthy cortisol levels in adults under chronic stress. L-theanine adds calm focus without sedation. Magnesium completes the wind-down.
-
03
Hair structure needs nutrients too
Zinc, biotin (moderate dose), silica, and B-vitamins support keratin production, follicle function, and structural integrity. We deliberately kept biotin at 1,200 mcg — below the dose linked to acne and lab-test interference.
Honest claims
Every line of copy passes a compliance review.
Supplement marketing is full of dramatic promises. Ruubyn® refuses to play that game — and the FDA + FTC are increasingly punishing brands that do.
What we say
- Supports the body's healthy stress response.
- Supports normal hair follicle function.
- Supports calm focus and a relaxed evening.
- Supports keratin production and hair strength.
- Supports nervous-system relaxation.
What we don't say
- Treats hair loss.
- Cures anxiety or depression.
- Replaces medical diagnosis or treatment.
- Reverses androgenic alopecia (genetic balding).
- Works the same for everyone, every time.
The FDA does not evaluate dietary supplements before they go to market. Honest expectations are the only durable currency in this category.
