Intolerance Lab will carry out a full testing program on your hair sample, which might reveal a hidden food substance intolerance or a pet allergy, a dietary allergy or a household product allergy. Most intolerance conditions are associated with a particular food or drink you consume and so finding a remedy is simply a matter of avoiding the products that make you feel unwell. However, with so many possibilities, only an intolerance test can reveal the truth. It seems many doctors won`t prescribe the intolerance tests as a standard procedure, due to cost restraints on the NHS, so take the initiative and get tested anyway.
