Why Halo exists
Your serum is doing its job. Your dropper isn't.
When you drop scalp serum onto your crown, most of it never reaches your scalp. It coats hair shafts. It runs onto your forehead. It ends up on your hands. The actives you're paying for stop working before they get to the follicles.
Halo solves that one specific problem. It loads your serum into a reservoir and pushes it out through 72 bristle tips at scalp level, with 850nm light and 360° massage running through the same five minutes. The serum stays the same. The time of day stays the same. The amount that reaches the follicles is the part that changes.
Built around Grow & Glow's two-pump dose. Compatible with any scalp serum or oil.

How the ritual works
Three modalities, one five-minute window
Halo runs all three at the same time. There's no mode-switching and no separate massage step after the serum. Load two pumps, press the button, glide across your scalp for five minutes. That's the routine.
1
Built-In Serum Applicator
A detachable 3ml reservoir holds about a week of serum at the standard two-pump dose. The bristle tips dispense at scalp level instead of letting the dropper coat your hair shafts. If the rest of your routine has been a guessing game, this is the part that ends the guessing.
2
850nm Red Light
Near-infrared LEDs run for the full five minutes. 850nm light supports the scalp environment in a photobiomodulation routine, the same family of light therapy used in scalp-care and skincare devices. It runs alongside the massage and the serum so the routine happens in one window instead of three separate steps.
3
360° Scalp Massage
72 silicone bristles run the kind of standardized scalp massage shown in published research to measurably increase hair thickness over 24 weeks. Four minutes a day was the dose. Almost no one manages it manually for six months. Halo runs it for you, hands-free.
Why women trust Medyko
Built for the routine you already have
Halo is Medyko's first hardware product. It was designed around women who already use Grow & Glow and the routine they already follow.
12,000+ women
Already using Medyko Grow & Glow. 2,483 reviews at 4.7 out of 5. Halo is what they get when the serum routine becomes a deliberate five minutes.
Built to pair
Designed around Grow & Glow's two-pump dose. Works with any scalp serum or oil. No locked ecosystem, no proprietary refills, no subscription you have to remember to cancel.
Real trial, real timeline
Grow & Glow has a published clinical trial behind it — a +46% shift in the active growth phase after four months. Halo's job is to make sure the protocol actually runs for those four months, instead of fizzling out at week three the way most home routines do.
90 nights to decide
Use it for three full months. Don't love it? Full refund. No awkward emails, no restocking fees, no questions.
The ritual, week by week
What changes, and what to expect
The hair-growth outcomes you read about with Grow & Glow come from the serum's clinical trial — a +46% shift in the active growth phase after four months. Halo's job is to make that protocol consistent, so the chemistry has the months it needs.
Week 1
The routine clicks
The first session is the one where the routine stops feeling like a chore. The serum stays on your scalp instead of running down your forehead. Your hands stay clean. The bristles handle the kneading your fingertips always gave up on. By the third night, you've already used your serum more deliberately than you did all of last month.
Weeks 2–4
Consistency without effort
Three nights a week, five minutes a session. The reservoir holds about a week of serum, so you're not running back to the cabinet between sessions. Scalp tends to feel calmer and less weighed-down. Roots stay less greasy because the serum is at scalp level, not coating the hair. This is the stage where most home devices end up in a drawer. Halo doesn't, because it's replacing a task you already do badly, not adding a new one.
Month 2
The bundle starts to work
By eight weeks, you're at the point where Grow & Glow's clinical trial recorded its early visible changes. Many women notice reduced shedding, a calmer scalp, and fine new hairs at the temples and along the part. The change here belongs to the serum. Halo's contribution is that the protocol has run consistently for eight weeks, three nights a week, the way the chemistry needs.
Month 4–6+
What consistency buys you
Grow & Glow's clinical peak sits at 4–6 months, the timeline Dr. Sofia Roth recommends. By this stage, Halo's contribution is that the routine has run consistently for the full 16 to 24 weeks. Most serums never get this chance because most women stop somewhere around month two. Halo is the device that makes the math work.
From real Medyko users
How four women fit Halo into their week
Halo's routine is five minutes, three nights a week. Here's how it lives inside four different weeks. From the Tuesday-night unwind to the postpartum shower.
“I used to drop the serum on my crown and watch most of it run down my forehead. Now I load Halo before bed and use it for five minutes while I scroll tomorrow's calendar. The serum reaches my scalp. My hands stop smelling like a chemist's bench. That's the part nobody warned me about.”
— Katja, 36
“I have about seven minutes between baby naps to do anything for myself. Halo is one of those seven minutes. IPX7 means I do it in the shower while the conditioner sits in my hair. No mess, no extra step, no deciding between my hair routine and the baby.”
— Lara, 31
“My bathroom drawer has a scalp brush, a vibration massager, and a half-empty serum I bought last year. Halo isn't in that drawer. It sits on my counter. The reason it stays out is that it makes the routine I'm already doing easier instead of harder. That's the only reason I kept using it.”
— Irena, 58
“I've spent ten years trying to stop my hair from thinning. I read the Grow & Glow study. I believed the science. The thing that finally clicked wasn't a new formula. It was using the formula I already trust, properly, three nights a week, for four months without skipping.”
— Petra, 42
Three steps, five minutes
How to use Halo
1
Load the reservoir
Twist off the detachable 3ml reservoir. Add two pumps of Grow & Glow (or your preferred scalp serum or oil). Twist it back on. The reservoir holds about a week of daily serum at the standard two-pump dose.
2
Press the button
Press the top button to power Halo on. The 850nm red light activates. Pick your massage speed; there are two. The serum-dispensing mode runs alongside the light and the massage, so all three modalities happen inside the same five minutes.
3
Glide across your scalp
Glide the wand across your scalp for five minutes, focusing on the part line and any thinning zones. The bristles dispense serum at scalp level while the light and massage run. Auto shut-off triggers at around ten minutes, so you can't accidentally overdo it.

Try Halo for 90 nights
Use Halo three nights a week for three months. If the routine doesn't feel like an upgrade, if the serum still feels like a drop-and-hope, if the device sits unused on your bathroom counter, send it back. Full refund. No questions, no restocking fee, no awkward exit interview.
The five-minute ritual that
makes the rest of your routine work harder
Two pumps of Grow & Glow into the reservoir. Five minutes, three nights a week, in the shower or before bed. The serum stops dripping. The massage gets done. The 850nm light runs the whole time. Same serum, used the way it was meant to be used.
Because most of the serum you're dropping onto your crown isn't reaching your scalp. Independent scalp-serum testing (Glow Guide Reviews, 2026) suggests around 80% of dropper serum coats hair shafts rather than scalp skin. Halo pushes your serum out through 72 bristle tips directly at the scalp, with 850nm red light and 360° massage running through the same five minutes. You're not changing your serum or your routine. You're just stopping the part where most of the formula gets wasted.
Three things at once, in one five-minute session. The serum dispenses through 72 silicone bristle tips at scalp level. 850nm near-infrared LEDs run throughout the session as a photobiomodulation routine that supports the scalp around the follicles. The 72 bristles deliver 360° kneading at the same time. Halo's job is to make the serum routine you already follow do more of what it was meant to do.
Five minutes a session, three nights a week. Week one is the ritual gain. The serum stops dripping, your hands stop smelling like a chemist's bench, the routine takes five deliberate minutes instead of thirty careless seconds. By weeks two to four, the scalp tends to feel calmer and the roots less greasy. The hair-growth numbers people quote about Grow & Glow come from the serum's clinical trial — a +46% shift in the active growth phase over four months. Halo's contribution is that the protocol runs from week one to week sixteen without interruption. Peak results match the serum's clinical timeline at four to six months.
No. Hair that comes out during gentle massage is already at the end of its growth cycle and would have shed anyway. Halo's silicone bristles are designed to stimulate, not pull. Published research on standardized scalp massage shows that four minutes a day, over 24 weeks, measurably increases hair thickness. Massage supports the follicles still in the active growth phase, not the ones already on their way out.
Halo uses topical, LED-level red light. There's no systemic absorption, no drugs, and no hormonal compounds anywhere in the device. The serum you load is whatever you choose; Grow & Glow itself is drug-free and non-hormonal. As with anything during pregnancy or breastfeeding, we recommend running it past your healthcare provider. At consumer LED levels for cosmetic use, there are no published contraindications.
Yes. The 3ml reservoir works with any liquid scalp serum or hair oil. Halo is built around Grow & Glow's two-pump dose, but there are no proprietary refills, no locked apps, and no subscription. We made the choice not to lock you in.
Yes. Halo is rated IPX7, meaning it's sealed against water immersion at standard depth. You can use it on a wet scalp, in the shower, or before or after washing your hair. Some women fit Halo into their conditioner-on minutes. Others prefer it at night, before bed. Either rhythm works.
Every Halo is covered by a one-year manufacturer's warranty against defects, plus a 90-day money-back guarantee. Use it for three months. If it doesn't earn its place on your bathroom counter, send it back. Full refund, no awkward emails, no restocking fees.
