To eight ounces of distilled water, add 15 drops oil of bergamot, 1 tblsp glycerine and 10 drops oil of rosemary. Apply this to the scalp before bed, accompanied with vigorous scalp massage.
To this procedure I would also add taking the B vitamins biotin (8mg daily) and folic acid (2-3 mg daily).

Antibiotics like Pentasa tends to interfere with PABA and folic acid metabolism, which can predispose to increased activity of yeast on the scalp. This can result in destruction of the hair follicle and loss of hair.
