The medication Oncotrex
you was prescibed at the first time was a type of anti cancer
medication and it has the side effect of hair loss which you suffered and the dose was also very high. At the first time the medication prescibed for the discoloration was not correct, as you told that it is because of some infection.
The medication prescribed to you after this is mainly a multi vitamine and a steroid
lotion, the muti vitamine will help to improve your general condition and the steroid lotion can reduce the localised inflammation which may be there because of side effect of previous medication.
By the way try to maintain a good health and nutrition and I hope you will get your hair back soon.
Thanks and take care.
