Will Intake Of Vitamin C With Zinc Prevent Hair Loss Which Can Possibly Be Due To Starting Acne Medication Acutane?

I will be starting a acne medication isotretinion also known as Acutane, and,my worries is hair loss. I do not have a family history of hair loss an I don't suffer from stress, I also don't have dry and brittle hair to begin with, but I am still concerned about hair loss. I have did some research on the medication, and I have read that if I take vitamin c and zinc it can prevent hair loss, also keeping the scalp moisturized will prevent hair loss. So what do you recamind me do to as far as perventing hair loss?
