Itching and hairloss can most definitely occur as a result of an allergy and withdrawing the suspected cause is the most sensible option. Hair growth will take 6-8weeks but if there is already a reduction in the itching and discomfort then this is a positive sign. Continue to monitor and I Recommend adding an omega fatty acid supplement such as viacutan to her diet also
