What if the client has little or no hair
Where scalp hair is not available or is too short for optimal testing, then body hair or in some cases facial hair can be used as an alternative. However interpretation of EtG and FAEE testing is less precise and the results are not always definitive.
Testing body hair is also helpful in addition to scalp hair where scalp hair is shorter than optimal or where repetitive use of hair treatments may have compromised the reliability of the testing. FTS will advise on the best options as required.
