Seasonal Summer Recurrent Dermatisis has typical symptoms : rashed tail and mane essentially. But careful, this symptoms are not only the result of the SSDR. It can be an allergy to other elements, such as food, herbs or other parasists (acarians...). Consult you veterinarian to obtain analysis and ask him to search for "seasonal parasitism".

Derfen is efficient on all skin problems but sometimes you could need a complementary treatment.

Remember that 40% of horses touched by SSRD are not developping a SSRD !!
