Good dermal cream for hair growth?
Short version: I know this question has been asked a million times, but... I'm not looking for something to treat scratches, rather, I'm looking for something to put on his skin now that it has recovered from dermatitis. Harley battled a bad case of scratches on his two front legs for about the last month. The worst of it is over, scabs have come off, exposing bare skin. It appears to be somewhat thickened, possibly even slightly granulated in some spots. What do you recommend to put on it? I've tried a number of things, but am not seeing results I'm really happy with yet. Not MTG please - I won't take a chance that he reacts to it. The dermatitis is gone now, there is no infection, skin is pink and looks ok, but I feel he needs a different kind of cream now to encourage hair to regrow and protect the skin.
More background before you suggest diet or lifestyle changes: for those who don't know - Harley is prone to skin issues, and has an excellent diet consisting of hay, grass, and timothy-only hay cubes, as well as some molasses-free beet pulp. He is also on supplements containing pre and probiotics, zinc, copper, and a bunch of other things as per his very own equine nutritionist. He is also on camelina oil which has actually made his grey coat shine for the first time since we've had him! However, he is 20, has not always had excellent nutrition, and does have a number of mild, but chronic issues which I manage to the best of my ability.
I do believe that the scratches (dermatitis) are actually a reaction to alsike clover in the back pasture, because he and Rusty -- my two pink-nosed guys -- came in with blistered noses one day, and Harley's legs erupted soon after (Rusty also has one spot on his one pink pastern). I pulled a few clover plants and believe they are alsike. So I mmediately closed off the pasture, and we have since plowed everything under, replanted, and are now letting it grow up. They won't likely be on it again until next summer.
The noses completely healed in a few days with some zinc oxide cream lathered on heavily, but Harley's legs were a mess. We have been washing them twice a day with Hibitane, applying Viaderm cream (a steroid) which costs 50$ a tube, and once they stopped bleeding and the worst of the scabbing was over, I started using Silver Whinnys (socks) which helps keep the flies away while wicking away moisture. Still, not much hair is growing and he has pretty big bald patches on his legs (I can try to get photos tomorrow). I was using something with Aloe Vera gel in it, but it didn't do anything. So I need a good dermal cream, preferably something that will not attract a bunch of dirt, that will keep his skin healthy and moist while it recovers and grows new hair. Hopefully something that does not cost 50$ for a tiny tube that lasts about a week.
Thanks for your suggestions!
