Why does my horse’s coat lift out in tufts when I brush it?

Overview
If your horse’s coat is coming away in tufts when you brush, rain scald is one common reason, especially if the skin beneath looks crusty, scabby or sore. It can also happen with other skin issues, so it’s worth checking the skin closely rather than assuming it’s just a dirty coat.
In many cases, the key clues are where it’s happening, what the skin looks like underneath, and whether the horse is also itchy, damp, muddy or living out in wet conditions.
Things To Check
1. Look at the skin under the lifted hair. Check for scabs, crusts, redness, moisture, broken skin or tenderness.
2. Note where the coat is affected. Rain scald often shows on the back, rump, neck or other areas that stay damp.
3. Think about weather and turnout. Wet, muddy or very changeable conditions can make coat and skin problems more likely.
4. Check whether the horse has been sweating, hosed, clipped or rugged recently, as trapped moisture can matter.
5. See if the horse reacts when brushed or touched. Soreness can suggest the skin is irritated, not just loose hair.
6. Look for rubbing, itching or repeated scratching, which can point towards irritation from several possible causes.
7. Check other horses on the yard if relevant, to see whether the issue seems linked to environment, mud or weather rather than one horse alone.
Common Causes
Rain scald is one of the most common causes. The coat can lift away in tufts and the skin may show small crusts or scabs, often after prolonged wet weather.
Damp coat or skin irritation can also cause hair to loosen if the horse has stayed wet for long periods or has been repeatedly rugged while damp.
Skin sensitivity, mud, sweat or grooming irritation may leave the coat looking patchy or unsettled, even without a clear infection.
Less commonly, other skin conditions can cause similar signs, so the appearance of the skin underneath matters when deciding what to do next.
What To Do
Gently part the coat and inspect the skin rather than pulling at the tufts. If the skin looks sore or crusted, avoid aggressive brushing in that area for now.
Keep the horse as dry as you can, especially after rain, sweating or washing. If turnout is unavoidable, try to reduce prolonged exposure to wet conditions where possible.
Use a clean, careful grooming routine and remove only loose dirt and mud. If the area is sensitive, lighter grooming is usually kinder than repeated hard brushing.
Make a note of where the coat is lifting, how the skin looks, and whether it changes with weather or turnout. That pattern can help you decide whether the problem is improving or spreading.
If the skin is crusty, painful or getting worse, it’s sensible to ask your vet for advice, as some skin problems can look similar at first.
When To Contact A Vet
Contact your vet if the skin is very sore, oozing, spreading quickly, or if the horse seems unwell. Vet advice is also sensible if the problem keeps coming back or you’re not sure whether it’s rain scald or something else.
Products That May Help
If your horse’s coat is breaking up, lifting or looking unsettled after grooming, a gentle washing routine may help support day-to-day coat care and make it easier to keep the skin clean and comfortable.
