The Dermagic System is a four-step topical protocol for dogs and cats — cleanse, treat, target, restore. No steroids, no antibiotics, no immune suppression. It was built for the pets whose owners have already been round the vet, the steroid injections and the antibiotics without lasting relief.
This is the complete guide: what the system is, why it works, exactly how to apply each step, what recovery actually looks like week by week, and what to do when progress stalls.
What the Dermagic System actually is
Most pet skincare is a single product looking for a problem. The Dermagic System is the opposite — a sequence, where each step does a job the next step depends on.
| Step | Job | Product |
|---|---|---|
| 1. Cleanse | Strip grease, odour and debris so treatment can reach skin | Peppermint & Tea Tree Oil Shampoo + Conditioner, or a Skin Rescue Shampoo Bar |
| 2. Treat | Kill the yeast, fungus and bacteria in the follicle | Skin Rescue Lotion |
| 3. Target | Heal broken, weeping or stubborn localised spots | Hot Spot Salve |
| 4. Restore | Soften new skin, speed regrowth, prevent reinfection | Cell Restoration Crème |
Skip step 1 and the lotion sits on grease instead of skin. Skip step 4 and you get regrowth that breaks down again three months later. The order matters.
The problem the system was designed for
Chronic pet skin disease usually isn’t one thing. It starts as an allergy, a parasite, a hormonal shift or an injury — and then something opportunistic moves in. Yeast and bacteria live on healthy skin in small numbers. Damage the skin barrier and they multiply into the follicle, which is what produces the smell, the black thickened skin, the relentless scratching and the hair loss.
That secondary infection is why so many pets get better on steroids and then relapse the moment the course ends. Steroids suppress the inflammation and the itch. They do not touch the organism causing it — and by dampening the immune response, they can make the overgrowth easier. We wrote about that trade-off in detail in why we avoid steroids for pet skin conditions.
The Dermagic approach inverts it: clear the organism on the surface, and let the pet’s own immune system do the rebuilding it was always capable of.
How the formulations work
The active ingredient across the range is florets of sulphur — an elemental mineral, not a synthetic drug, used on skin for centuries for its antifungal and antibacterial action.
Worth being clear about, because the names look alike: sulphur is not a sulphate. Sulphates like SLS are synthetic foaming detergents that strip the skin barrier. Sulphur is a mineral that treats it. Dermagic uses the first and deliberately excludes the second. There’s a fuller explanation in sulphur: the healing mineral for pets and in parabens and SLS in dog shampoo.
Around the sulphur sit the repair ingredients:
- Certified organic whole-leaf aloe vera gel — anti-inflammatory, and a carrier that helps actives penetrate. More on aloe vera in pet skincare.
- Vitamin E — antioxidant, supports barrier repair
- Organic shea butter — occlusive, holds moisture in damaged skin
- Beeswax — makes the salve stick to a wound instead of running off it
- Therapeutic essential oils — rosemary, peppermint, tea tree; antimicrobial and soothing. See rosemary in Dermagic.
No perfumes. No artificial colours. No parabens or sulphates. Made in the USA with domestic ingredients, and non-toxic to pets and people — which matters, because every one of these products will eventually be licked.
Step 1 — Cleanse
Goal: get down to clean skin. Treatment applied over grease, scale and dead coat does very little.
Bath your pet with the Peppermint & Tea Tree Oil Shampoo, working it right down to the skin rather than over the top of the coat. Leave it on for five to ten minutes before rinsing — this is the step most people rush, and it’s where most of the antimicrobial work happens. Rinse thoroughly, then follow with the matching Conditioner to restore moisture.
For severe cases, bathe twice weekly for the first two weeks, then weekly, then fortnightly as the skin settles.

The Skin Rescue Shampoo Bar does the same job in solid form. It’s concentrated, so it lasts far longer than the equivalent bottle, needs no conditioner, and there’s no plastic to throw away.
| Liquid shampoo + conditioner | Shampoo bar | |
|---|---|---|
| Conditioner needed | Yes | No |
| Best for | Very greasy or heavily infected coats | Maintenance, sensitive skin, travel |
| Lifespan | Shorter | Considerably longer |
| Packaging | Plastic bottle | Plastic-free |
Either is a legitimate step 1. If you’re unsure, soap, shampoo or shampoo bars walks through the choice properly, and why use Dermagic natural shampoo and conditioner covers what’s in them.

This is the engine of the system. If you only ever buy one Dermagic product, buy this one.
Once the coat is clean and fully dry, massage the lotion into the skin — not onto the fur. Part the coat and work it in with your fingertips the way you’d use hand cream: enough to cover, not so much that it sits in a layer.
Dosing:
- Twice daily for the first 7 days
- Once daily thereafter, until skin and coat are visibly recovered
- Then as needed for maintenance or at the first sign of a flare
The t-shirt rule. Put a soft t-shirt, babygro or recovery suit on your dog afterwards and leave it on for at least an hour. Lotion that gets licked off in ninety seconds cannot work. This one detail is the difference between the system working and the system “not working” more often than any other.
For Black Skin Disease specifically, there are two dedicated application guides: how to use Skin Rescue Lotion for Black Skin Disease and Alopecia X: how to use DERMagic Skin Rescue Lotion.

The salve is the same active chemistry as the lotion, in a thicker beeswax base that stays put on a wound. The lotion covers territory; the salve holds a position.
Use it on:
- Hot spots and weeping acute moist dermatitis
- Insect bites and stings
- Small cuts, grazes and scabbed-over areas
- Cracked pads, chapped noses, scorched feet
- Any spot that breaks open during recovery from a wider condition
Dosing: dab a small amount on once or twice daily until the spot closes. Applied early to a minor bite or graze, it usually prevents the infection that would otherwise turn it into a full hot spot.
Keep a tin in the house permanently. See hot spots on dogs and how to treat them for the wider picture, and the Hot Spot Salve guide for detail on the product itself.

The step people skip — and then wonder why the problem comes back.
When new pink skin appears and fur starts pushing through, that skin is new, thin and fragile. The Cell Restoration Crème softens and protects it, speeds cell regeneration, combats the dry flakiness that comes with regrowth, and helps stop the whole cycle restarting.
Dosing: massage in as needed — typically once daily over recovering areas — from the point where regrowth begins until the coat is fully established.
It’s also the product to keep for winter cracked pads, chapped noses and dull coats long after the original condition has cleared.

Not part of the core four, but genuinely useful:
- Anti-Dandruff Salt Scrub — Dead Sea salts for deep exfoliation and detoxification immediately before bathing. Excellent for dry, flaky, dandruff-prone skin, and it makes step 1 considerably more effective on a heavily scaled coat. The therapeutic essential oils are relaxing for the pet and stimulating to the skin.
- Skin Rescue Grooming Spritz (Lemongrass & Spearmint) — between-bath freshening and light relief for itchy skin without a full bath.
- Skin Rescue Conditioner Bar — the plastic-free counterpart to the liquid conditioner.
- Organic Shampoo Bars — the wider bar range in other scents.
Supporting the system from the inside. The four steps work on the surface of the skin. A dog regrowing a full coat over three to six months is also under a real nutritional demand, and that part cannot be applied topically. The Mendota natural supplement range covers it — Retrieve Skin & Coat supplies the Omega 3, 6 and 9 the body uses to rebuild the skin barrier, and Retrieve Enzymes determines how much of the food’s nutrition actually reaches it.
What recovery actually looks like
Expectations are where most owners come unstuck. Skin recovery is fast; hair regrowth is governed by the hair cycle and cannot be hurried. Here’s a realistic timeline for a moderate-to-severe case.
| Timeframe | What you should see |
|---|---|
| Days 1–3 | Smell reduces noticeably. Scratching begins to ease. |
| Week 1 | Itching markedly calmer. Skin less angry. Some flaking as dead skin lifts. |
| Weeks 2–3 | Redness fading. Thickened or blackened skin starts softening and lightening. Scabs lifting. |
| Weeks 4–6 | Skin tone visibly changing. Fine fuzzy undercoat appears — usually the first unmistakable win. |
| Months 2–3 | Undercoat thickening into real coat. Bald patches shrinking from the edges inward. |
| Months 3–6 | Full regrowth on severe cases. Transition to maintenance. |
If you see nothing at all after three weeks of consistent, correct application, something in the protocol is off — see the next section — or the underlying driver isn’t microbial and needs a veterinary diagnosis.
Five things that stall progress
- Applying to fur, not skin. Part the coat. Fingertips on skin. Every time.
- Letting it get licked off. T-shirt or recovery suit, minimum one hour.
- Stopping at week three. The itch stopping is not the condition being cured. Follow through to regrowth.
- Skipping the bath. Lotion on a greasy coat is lotion wasted.
- Ignoring the underlying cause. If it’s a flea allergy, treat the fleas. If it’s food, address the food. The system clears the infection brilliantly; it can’t stop a trigger you’re still exposing your pet to. Start with the most common skin conditions in dogs and cats or dog allergies — or is it actually a yeast infection?.
Using the system on cats
Cats are not small dogs. They groom obsessively, they metabolise essential oils differently, and their skin pH isn’t a dog’s.
Never apply a concentrated tea tree oil dog product to a cat. Use the feline range instead:
- Feline Skin Rescue Lotion — the step 2 equivalent, formulated for feline sensitivity
- Rosemary Shampoo Bar for cats — gentle, organic, safe for kittens
- Feline Shampoo Bar — the natural bath option for cats
Bathing a cat is its own discipline. Bath time for cats covers how, and how often.
Does it actually work?
We’d rather show you than tell you. These are real cases documented on this blog:
- Gunner — hair loss and blackened skin following surgery; full regrowth
- Yogi the Pomeranian — Black Skin Disease recovery
- Sir Winston — another Pomeranian, same outcome
- A Golden Retriever — full regrowth over five months
- Gus — losing hair, skin turning black, turned around
- Our happy customers — in their own words
If your pet’s situation matches one of those, that post is worth reading before you start — the specifics of each case tend to answer questions this guide can’t. For the condition itself, Black Skin Disease in dogs (Alopecia X) is the complete guide.
Breed-specific guides
Some breeds need the protocol adapted rather than followed as written. If yours is here, read the breed guide alongside this one:
- French Bulldog — skin folds, tail pocket, narrow ear canals
- Pomeranian — Alopecia X and Black Skin Disease
- Golden Retriever — hot spots under a heavy double coat
Where to start
Match the protocol to what your pet actually has — then run all of it. Each row below is the full course for that situation, not a shortlist to choose from:
| Your situation | Start with |
|---|---|
| Widespread hair loss, blackened skin, Black Skin Disease | Shampoo + Skin Rescue Lotion + Cell Restoration Crème |
| One or two hot spots, bites, localised flare | Hot Spot Salve |
| Itching and smell across the body, greasy coat | Shampoo + Skin Rescue Lotion |
| Dandruff, dry flaky skin, dull coat | Salt Scrub + Shampoo + Cell Restoration Crème |
| Maintenance after recovery | Shampoo bar + Cell Restoration Crème as needed |
| A cat, any of the above | Feline Skin Rescue Lotion + Rosemary Shampoo Bar |
The Skin Rescue Lotion does the heavy lifting in every row it appears in — but it works markedly better on a properly cleansed coat, and the crème is what protects the coat you’ll have spent months regrowing. Run the whole row.
