As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just use the pre-paid return label included in your order within 60 days from the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

Why We Love This

Keratex Hoof Hardener strengthens weak, worn and cracked hooves by improving the molecular structure of the horn itself. The gentle acting chemical formulation forms additional intermolecular bonds between molecules of keratin through the process of cross-linking, producing a tougher, stronger horn structure. Keratin is the main protein constituent of horn and is best described as the building block of the horn structure. 

Apply to lower half of hoof and sole, avoiding coronary band and frog. Use daily for one week then twice weekly for general hoof maintenance. If the hoof has been treated with any oils or greases over the past three months, degrease the hoof thoroughly with acetone before applying Keratex Hoof Hardener. Do not use any oils or greases while using Keratex Hoof Hardener.

Made in the UK.

Due to federal regulations, we are unable to offer expedited shipping, or ship to Alaska and Hawaii for this product. Please note this item may ship separately from your order. We sincerely apologize for any inconvenience.

Favorite Features

  • Strengthens, hardens, and protects hooves. 
  • Equally effective in wet & dry conditions.
  • Prevents the horn from taking in excess moisture, making it resistant to softening and weakening in wet conditions. This results in a reduction in shoe loss and abscesses.
  • Keratex Hoof Hardener is not an oil or resin layer and does not seal the hoof.
  • Keratex Hoof Hardener will ensure the treated hoof is able to breathe naturally so the moisture balance is properly maintained.
  • Should also be applied to the sole of the hoof to prevent bruising.
  • Includes brush for application.
  • Great for use on both shod and unshod horses because of its hardening and strengthening effect.

    Keratex Hoof Hardener is rated 4.7 out of 5 by 180.
    Rated 5 out of 5 by from Fantastic product I have been using Keratex Hoof Hardner for about 2 years now. This was recommended by my farrier and I've followed the instructions for use. My horse has gone from throwing shoes every 2 weeks to keeping them on for a solid 5 weeks (our shoeing schedule), and he lives out in a field 24/7. His hoof quality has greatly improved from the use of this product, and my farrier recommends sticking with it's use. I must also state that I have my horse on SmartPak Hoof Supplement as well, but have no plan to discontinue the use of Keratex as it has been essential in keeping my horse sound and shod.

    Rated 2 out of 5 by from So far no change Been using this everyday for a few weeks. Not really seeing a difference but I have not spoken to my farrier. He would be more qualified to tell me if it's working.

    Rated 4 out of 5 by from It works! My gelding has been on hoof supplements for years due to his sensitive soles and has never been able to go barefoot. He still must wear shoes to walk across rocks and gravel to get to the riding arena, but as of today he no longer had to tip-toe up the driveway!Keratex is not easy to apply and you must wear gloves as the liquid is a watery consistency that can burn the skin as well as the frog of the hoof.

    Rated 4 out of 5 by from Great product. Works super. Use it when transitioning a horse from shoes to barefoot for the winter. Wish it came with an applicator bottle.

    Rated 5 out of 5 by from work fast I bought this product a few months ago for a few horses that were having trouble keeping shoes on. Their feet were very shelly around the nails of their shoes. This product helped very quickly.
    Date published: 2015-12-27
    Rated 5 out of 5 by from Farrier/vet recommended My horse doesn't have the best of feet and they tend to get soft when its wet out and he throws shoes. I use this about 2 to 3 x's a week and it really helps with keeping his shoes on. Its the only thing I have found to work!
    Date published: 2015-12-18
    Rated 5 out of 5 by from Great for barefoot horses! I pull my horses' shoes in the winter/non-showing season for us. He does pretty well when his shoes are first pulled, but he usually need a week to adjust. This helps SO much!!!!! I wish I knew about this earlier than this year!!!! It is worth the money for sure!

    Rated 5 out of 5 by from Bob's Shoes are Staying On!! Bob is an OTTB. He seems to have the notoriously soft hoof walls that come with being a thoroughbred. All four of his hooves are light as well, so Bob is doubly blessed in that regard. Before starting Bob on Keratex, he consistently lost his shoes before the farrier's next visit, and his feet literally looked like he chewed his nails. After two months with Keratex, Bob is keeping his shoes on and the general appearance of his feet is much improved. Some of the reviews mention how messy application of this product can be. I heartily recommend using a paint bottle with a sponge tip applicator. I got mine from Amazon.

    Rated 4 out of 5 by from Easy to use, highly recommended We have seen small changes already on our thin soled gelding. Only been using the product for 3 weeks now, excited to see the future weeks to see how keratex impacts his crumbly feet. Highly recommended by our farrier.

    Rated 5 out of 5 by from Life saver for my poor mare! I bought this product on the recommendation of my farrier. My poor mare abscessed 3 times in three months and has such soft, tender soles, she could barely walk. My vet recommended that she stay in during muddy season but that is not practical for her. I started applying Keratex Hoof Hardener and after 12 days, she is sound again and has nice hard soles. I am on maintenance of just twice a week now and bought EasyCare easy boots RX for the really bad muddy weather. I may not even have to use them. Great product. I highly recommend it.

    Rated 5 out of 5 by from Really helps make hooves better! I have been using this product for several months on my warmblood. His hooves were very brittle, and he was constantly breaking up. I have been using it every other day, and his hooves have really improved. Much stronger, no breaking up. I highly recommend.
    Date published: 2015-09-21
    Rated 5 out of 5 by from It works!! Both my horses have been barefoot for years and never had problems until this spring. The footing in the ring was very hard and they both became foot sore. They also developed cracks as well. I bought a bottle of Keratex and applied it once a day for 7 days. Afterwards, I applied it twice a week. Wow- after a month there was major improvement and their hoofs were no longer sore! I am a believer!! The farrier was very impressed as well. My only complaint is the bottle- I just transfer the liquid into a can with a brush to avoid spilling.
    Date published: 2015-08-24
    Rated 5 out of 5 by from So far so good! My TB gelding has been battling abscesses in his front foot and the sole has been very chalky and crumbling. I applied this product daily for the first week and have noticed a huge difference already! The sole is much harder and the crumbling has almost stopped. Will definitely keep up with the weekly applications.

    Rated 5 out of 5 by from All my farriers Recomend it Every farrier I ever had has recommended using it.
