Precision Microneedling for Stronger, Fuller Hair & Beard Growth
1200 titanium needles stimulate dormant follicles through controlled micro-trauma — the clinical-grade tool that turns patchy into powerful, at home.
Three pillars of professional-grade performance

1200 Titanium Needle Array
Titanium resists corrosion and stays sharp for months of weekly use. The dense 1200-needle configuration creates overlapping micro-trauma for even, efficient coverage — no missed spots.

Hygienic Storage & Portability
The included ceramic bowl keeps the roller clean and protected between sessions. Compact enough for your gym bag or travel kit — your routine, wherever you go.

Ergonomic Scandinavian Design
The soft-touch matte dome fits naturally in your palm, reducing hand fatigue during use. Aesthetic enough for the bathroom counter, precise enough for professional results.
The numbers behind the growth
- 1,200Titanium needles
- Up to 300%increased absorption when used with topical serums
- 6+ monthsneedle sharpness when used weekly
- Replaceablefor extended device life
3 minutes to activation
- 1Cleanse & Disinfect
Wash your face or scalp thoroughly and disinfect the roller head with 70% isopropyl alcohol. Dry the skin completely — never roll on damp skin.
- 2Section & Roll
Divide the target area into sections. Roll vertically, horizontally, and diagonally 4-5 times in each direction, applying light pressure. Expect mild redness that fades within an hour.
- 3Apply Actives
Immediately after rolling, apply your growth serum or topical treatment. The micro-channels are open for about 5 minutes — this is your window for maximum absorption.
- 4Clean & Store
Rinse the roller under hot tap water, then soak in alcohol for 10 minutes. Let air-dry completely before placing back in the ceramic bowl. Avoid wiping with towels.

Illustrated step-by-step instructions and care tips
From Thinning to Thriving
The Silent Thinning
You notice it first in the mirror — a receding hairline, a beard that refuses to connect. Your medicine cabinet fills with hair accessories and expensive serums, but nothing targets the root cause. The follicle itself is still alive, just dormant. It needs a trigger.
The Intervention
1200 titanium needles — spaced at 0.25 mm — create thousands of micro-channels across the scalp or beard area. The controlled trauma signals your body’s repair cascade: increased blood flow, collagen induction, and a surge of growth factors exactly where it’s needed. This isn’t a Scalp massage brush — it’s the activation key.
What to expect, week by week
- Week 1–4Adaptation Phase
Skin becomes accustomed to the treatment. Expect slight redness for a few hours post-rolling and possibly minor shedding of weak hairs. This means the follicle cycle is resetting.
- Week 4–8New Growth Emerges
Tiny, vellus hairs begin appearing in previously thin areas. The beard line starts filling in; scalp density looks less sparse. Serum absorption is at its peak.
- Week 8–12Visible Thickening
Those baby hairs mature into terminal, pigmented strands. Hair caliber increases, coverage improves, and the difference becomes noticeable to others.
- Week 12+Maintenance & Full Results
Continue weekly sessions to lock in gains. Density plateaus around 6 months — at this point, you can space sessions to every 10–14 days and maintain progress indefinitely.
Care notes
- Disinfect before & after
Soak the roller head in 70% isopropyl alcohol for 10 minutes before first use and after every session.
- Air‑dry completely
Never wipe the needles with a towel — let them air dry on a clean surface or inside the bowl to prevent contamination.
- Replace your cartridge
Titanium needles start to dull after 6 months of weekly use. Swap in a fresh cartridge to maintain performance and comfort.
- Don’t share your roller
Microneedling creates temporary micro‑channels. Sharing the device can transfer blood‑borne pathogens — this tool is strictly personal.

Questions and answers
For optimal results, use once per week on a clean scalp or beard area. Overuse can cause irritation and won’t speed up results. Consistency is key — aim for at least 3 months to see visible changes.
More needles create a more uniform micro-trauma pattern, which reduces skipped areas and improves serum absorption. 1200 needles also allow faster coverage of a larger area. For hair and beard growth specifically, the dense array is a significant upgrade.
The sensation is prickly but tolerable — most users describe it as a mild scratch. Using a numbing cream 20 minutes before your session makes it nearly painless. The titanium needles are very sharp and cause minimal discomfort.
Absolutely — in fact, it’s recommended. Microneedling creates micro-channels that increase serum absorption up to 300%. Apply your serum immediately after rolling for maximum penetration.
After each use, rinse the roller head under hot water and soak in 70% isopropyl alcohol for 10 minutes. Let air-dry completely before storing in the included ceramic bowl. Do not share your device.
Yes, the Bio Roller G4 is unisex. Many women use it to improve scalp health and stimulate regrowth in thinning areas. Follow the same weekly protocol.
