First of all, what is Trichodynia? Trichodynia is a condition where the patient experiences a painful sensation on their scalp. The pain sometimes is described as burning. Trichodynia often is associated with hair loss, but some studies show it has no connection to hair loss. Often there is an underlying psychosomatic cause, such as stress, depression or anxiety.
In this study, the patients zinc, folate and vitamin B-12 serum levels were evaluated, along with specific psychological tests to determine which causes these symptoms. The conclusion, no serum deficiencies caused hair loss. Trichodynia is more psychosomatic in nature and normally dealt in that manner.
