Mallenders & Sallenders, what? Most horse people have never heard of these funny sounding and antiquated names, and unless you have a Gypsy, Shire, Drum, Friesian or horse with heavy feather you're likely to never see it.

Sallenders occurs in the crease of the knee on the front leg and Mallenders is present in front of the hock on the hind legs. You'll recognize it by the thickened, crusted scale and scabs on the front and hind legs of horses. Sallenders and Mallenders can become extremely uncomfortable for your horse and if left untreated can cause secondary fungal and bacterial infections that lead to lameness.

The cause of Sallenders and Mallenders is the overproduction of keratin; the building block of hair, horn and that beautiful, luxurious feather. There is no cure for Sallenders and Mallenders but it can be managed easily. Farriers Ointment will gently soften the waxy build-up in a couple of days and the scabs will start to drop off. Farriers Ointment will also help prevent and address any infections associated with this condition. It is a simple, safe and natural treatment and will have your horses legs smooth and free of scabs, cracks and pain in a very short time.

They describe the same condition, but are different in where they occur on your horse's body. Mallenders shows up on the back of the knee on the forelegs, and sallenders in front of the hock on the hind legs. While the name may sound funny the condition is not.

You'll recognize mallenders or sallenders as hard crusts and scale in both locations. It is caused by excess keratin exuding from the skin and drying there. Keratin is the key structural protein that makes up hair, horns, claws, hooves, and the outer layer of skin. In horses with feather the body produces more keratin than in non-feathered breeds. This is what accounts for the lush feather, but in the case of mallenders and sallenders too much and allowing it to remain can cause big problems.


  1. Day one - Wash the area well with Equiderma Neem Shampoo. Leave shampoo on for up to 1 hour, rinse and dry well. Equiderma Neem Shampoo will soothe your horses' skin and calm the inflammation. It will also help to address any mites or dermatophytes present by halting the feeding and life cycle of these invaders.
  2. Apply Equiderma Skin Lotion to all crusts and build up and leave on. The goal is to soften the crust, so it is easily removed. Don't get in a hurry. Aggressive removal before it has softened and is ready for removal can cause more pain for your horse and trauma to the skin.
  3. Re-apply Equiderma Skin Lotion every day and gently attempt to remove the dried scale and chunks. In advanced cases you will need to apply every day for up to three days. Let the skin lotion do its job. It will soften the crusts while also addressing any bacteria and fungus living on the skin. It is a simple, safe treatment and will have your horses’ legs smooth and free of scabs, cracks and pain in a very short time.
  4. You'll soon notice the crusts have softened and are crumbling. Now is the time to comb them out. Just use a wide toothed comb and gently remove the buildup. You'll notice the skin is healthy now.
  5. Observe area often for any signs of new buildup and re-apply as needed.
  6. If temperatures are low or for any reason you cannot shampoo your horses' legs, the Equiderma Skin Lotion will do an excellent job on its own.


To date there is no definitive cure for mallenders and sallenders. It requires ongoing management. Care and vigilance to ensure your horse's feather and underlying skin is healthy is necessary. Feathers must be kept clean and any sign of mallenders or sallenders should be dealt with right away. Avoid the possibility of bacterial infection through good management and prompt treatment. Removal of dried keratin build up is essential and its presence should never be treated carelessly.







1. Is Equiderma more effective than oil treatments, medicated shampoos and creams?
Yes, one of the great challenges of mallenders and sallenders is removal of the dried crusts while also addressing inflammation, bacteria, fungus. Equiderma Neem Shampoo will gently clean the feather and skin while soothing and calming the inflammation. It will also aid you in controlling any mites and dermatophytes present (organism responsible for scratches). Equiderma Skin Lotion is the most effective solution for softening the scabs and addressing any bacteria and fungus present.

2. How do I prevent mallenders and sallenders?
There is no definitive cure for mallenders and sallenders. Many of our customers report success by simplifying their horses diet, omitting all wheat and supplementing with micronized linseed oil.

3. Is hyperkeratosis contagious?
No, it is not contagious.


"Gypsy Lakeridge So British, that I love dearly and have owned since 2011, has been suffering from what I now know is mallenders and sallenders. 4 vets have seen him over the years. I even went to the Veterinary Hospital to see a dermatologist and the diagnosis was always the same; clip the legs and put lime sulfur on it. There was no way I would do that. I have tried everything and anything to help my horse. I even ordered a product from France (which I had to have a personal clearance from Santé Canada), more than 1 case of MTG, 1 bag of 50 kg of sulfur mixed with mineral oil, Young Thieves oil, many essential oils mixed with zinc other mixtures. Then I was introduced to Equiderma Skin Lotion. Only 1 application the evening I got it and the next morning the scabs that had been there for months and couldn't get off, came off by themselves! I since put some on everyday just to be on the safe side and he has been free of all crusts and scale since. This product is THE MIRACLE I was hoping for. The lotion has saved my horse and took a heavy load off my shoulders."

"This is the second time I have bought this lotion for my horse who suffers from mallenders. I can honestly say this is the only thing that works after 13 years of trying various other lotions. Customs and postage bump up the price but for me it is worth the expense."

"This winter my 7 yr old Gypsy gelding had a real flare up. In the past I used MTG, but I noticed he really avoided having it applied. I figured out he is sensitive to the sulfur, so I am doing the Equiderma Neem Shampoo with the Skin Lotion. At first, from habit my gelding avoided me trying to put anything on his legs. He is now shedding off the scabs behind his knees and hopefully now the scar tissue will become less inflamed. So far, I feel I will not be without this lotion. It is a soothing and effective approach for mallenders treatment."
