Root Renewal Supplements

Are Bomme’s Root Renewal Supplements effective?

In a 24‑week, randomized, double‑blind, placebo‑controlled clinical trial published in Skin Research & Technology (2023), participants who took the BLH308 supplement formula showed statistically significant improvements in hair density and thickness versus placebo. Some participants reported noticing changes by 8 weeks, with greater changes at 16 and 24 weeks. Individual results vary and depend on factors such as genetics, health status, and consistency of use.

What are the key ingredients?

Bomme’s Root Renewal Supplements feature a blend of:

Persimmon Leaf Extract (PLE): Antioxidant that helps defend against oxidative stress.
Green Tea Extract (EGCG‑rich): Antioxidant that supports healthy cell turnover.
Sophora Japonica Fruit Extract: Supports vascular health and provides anti‑inflammatory benefits.

How are these supplements different from hair‑growth medications?

Conventional medications (e.g., DHT‑targeting drugs): Often work by inhibiting 5‑alpha‑reductase, the enzyme that converts testosterone to DHT. This direct hormonal mechanism may be associated with hormone‑related side effects for some users.

Bomme approach: Our formula is designed to support a healthy scalp environment by helping normalize pathways related to 5‑alpha‑reductase expression in dermal papilla cells and by addressing inflammation. It is not a pharmaceutical 5‑alpha‑reductase inhibitor.

Why does inflammation matter for hair?

Chronic, low‑grade inflammation around hair follicles is linked to thinning and miniaturization. Pro‑inflammatory cytokines—such as IL‑6—can contribute to a less hospitable environment for robust hair growth. Bomme’s antioxidant‑rich ingredients are formulated to help reduce oxidative stress and support a calmer scalp environment.

What are the side effects?

The formula is generally well‑tolerated in healthy adults. As with any supplement, sensitivities can occur (e.g., mild GI upset, headache, skin flushing). Discontinue use and consult a healthcare professional if you experience redness, swelling, itching, or other concerning symptoms. Keep out of reach of children.

How should I take the supplements?

Dose: Take two tablets daily.
Timing: Consistency matters; take them at the same time each day. You may take with or without food according to your tolerance.
Duration: Use daily for 1 to 3 months for best assessment of results, then continue for maintenance if desired.

Are Bomme supplements for men or women?

Both. The formula is suitable for adults of all genders.

Do the supplements contain any drugs?

No. They are plant‑based dietary supplements, not prescription drugs.

Do the supplements expire?

Unopened products have a 3‑year shelf life from the manufacturing date. Store in a cool, dry place away from direct sunlight.

Can I take Bomme with other hair‑growth products?

Yes. The supplements may be used alongside topical products. If you’re using prescription therapies, check with your clinician for personalized guidance.

Should I stop taking minoxidil?

Minoxidil is a drug therapy. Do not stop or change any prescription or OTC drug without consulting your healthcare provider. Some people choose to use Bomme and minoxidil together.

Revitalizing Scalp Toner

Is Bomme’s Revitalizing Scalp Toner effective?

In a 4‑week clinical study conducted by P&K Skin Research Center (2023), participants saw improvements in hair density and thickness (up to 72% in study measures). Results vary by individual and usage consistency.

Who can use the toner?

Adults of any gender.

How do I apply it?

Apply to a clean, dry scalp.
Let hair air‑dry when possible; if blow‑drying, use a cool setting.

Do I need to wash my hair after applying?

No. Apply to a dry scalp and allow it to dry naturally. If you need to wash your hair, do so before applying the toner.

What are the side effects?

No serious adverse events were reported in our studies. If you notice redness, swelling, itching, or irritation, discontinue use and consult a healthcare professional.

Color‑treated or chemically processed hair?

Many customers use the toner with color‑treated or chemically processed hair without issues. If your scalp is sensitive post‑treatment, patch‑test first.

Does the toner expire?

Unopened toner has a 3‑year shelf life from the manufacturing date. Store cool and dry.

Hair Loss 101

What are common causes of hair loss?

Hair loss can result from genetics, hormonal changes, medical conditions (e.g., thyroid disorders, alopecia areata), medications (including chemotherapy), stress, nutritional gaps, aging, and hair‑care practices. A clinician can help identify your specific drivers.

There are several types of hair loss:

Androgenetic alopecia: The most common form; associated with follicle miniaturization and DHT sensitivity.
Telogen effluvium: A temporary shift of hairs into the shedding phase, often triggered by stress, illness, drastic dieting, hormonal changes, or sleep deprivation.
Alopecia areata: An autoimmune condition that can respond to specific medical treatments.
Other forms include hair loss linked to seborrhea, thyroid imbalance, chemotherapy, traction, and scarring conditions.

Can hair loss be prevented?

It depends on the cause. Genetics aren’t preventable, but you can support hair health by:

Managing stress and prioritizing sleep
Avoiding smoking and moderating alcohol
Eating a nutrient‑dense diet
Minimizing harsh chemical treatments and tight hairstyles
Seeking timely care for scalp or medical conditions

What’s the best way to shampoo your hair?

Use warm (not hot) water.
Choose gentle, fragrance‑free or hypoallergenic formulas if you’re sensitive; avoid harsh surfactants like SLS if they irritate you.
Massage lightly with fingertips—no nails.
Wait ~1 minute before rinsing.
Rinse thoroughly to avoid residue.
Air‑dry when possible, or use a cool dryer setting.
Avoid going to bed with wet hair to minimize irritation and breakage risk. If you have scalp conditions (e.g., seborrheic dermatitis, psoriasis, eczema), consult a dermatologist for targeted care.

“Learn More” (Expandable FAQ item)

What else should I know about hair loss and scalp care?
If you’d like to go deeper than quick Q&As, here are a few key points:

Causes of Hair Loss: Hair thinning can be linked to genetics, hormones, stress, illness, nutritional gaps, medications, or poor scalp care. Some types are temporary (like telogen effluvium after stress), while others (like androgenetic alopecia) are more long-term.
Inflammation & Hair: Chronic scalp inflammation—often triggered by excess DHT and pro-inflammatory cytokines like IL-6—creates an unhealthy environment for follicles, leading to miniaturization and shedding. Reducing inflammation helps support stronger hair.
Best Shampooing Practices: Use warm (not hot) water, gentle formulas (avoid harsh sulfates like SLS), and massage lightly with fingertips. Rinse thoroughly, let shampoo sit for a minute, and air-dry when possible. Avoid going to bed with wet hair, since moisture can trigger irritation, breakage, or fungal overgrowth.
Prevention & Lifestyle: Sleep, diet, stress management, and avoiding smoking/excessive alcohol all play roles. Early intervention makes a difference—consult a dermatologist if you suspect medical conditions are at play.

How Bomme Was Developed

In 2002, Dr. Jeong‑Moon Jeong founded a research facility in South Korea focused on natural remedies aligned with disease mechanisms. After more than a decade of screening food‑derived botanicals for hair health, the team identified a synergistic blend of Persimmon Leaf, Sophora Japonica Fruit, and Green Tea extracts. Ongoing work optimized the ratios to support scalp environment and follicle health.

Where are Bomme products made?

Formulated and produced in South Korea at an MFDS‑certified facility.

Do Bomme products undergo testing?

Yes. Our ingredients and finished products undergo safety and quality testing. Our supplement formula (BLH308) has been evaluated in a peer‑reviewed human clinical trial. The toner has been evaluated in a human clinical study.
