Hair Follicle Testing in Parenting Matters
Hair follicle testing is sometimes used in family law proceedings where concerns are raised about drug or alcohol use. This form of testing can provide information about substance use over a longer period of time and may assist courts in assessing parenting risk.
In parenting matters, the court’s focus is always the best interests of the child, including whether any substance use may affect a parent’s ability to safely care for their child.

What Is Hair Follicle Testing?
Hair follicle testing involves analysing a small sample of hair to detect traces of drugs or alcohol metabolites.
As hair grows, substances consumed by the body may be incorporated into the hair shaft. Laboratory analysis can then identify whether certain substances have been present in the body during the relevant testing period.
This type of testing can detect substances such as:
• cannabis
• cocaine
• amphetamines
• methamphetamine
• opioids
Hair testing may also be used to assess alcohol consumption through certain biomarkers.
Detection Period
Hair testing is often used because it can detect substance use over a longer timeframe than urine testing.
Depending on the length of hair tested, results may provide insight into substance use over the previous three months or more.
This can be particularly relevant where there are concerns about ongoing patterns of substance use rather than isolated incidents.
Advantages of Hair Testing
Hair testing can provide several advantages in parenting proceedings.
These may include:
• identifying longer-term patterns of substance use
• reducing the likelihood of short-term abstinence affecting results
• providing laboratory-verified evidence for court proceedings
Because of these factors, hair follicle testing may sometimes be preferred where long-term substance misuse is alleged.
Limitations of Hair Testing
Like any form of testing, hair follicle analysis also has limitations.
Factors such as hair treatments, environmental exposure, and individual biological differences may affect results. Courts will therefore consider hair testing results alongside other evidence when assessing parenting arrangements.
Testing results alone do not always determine the outcome of parenting proceedings.
How Courts Use Hair Testing Results
When hair testing is used in family law matters, the results may assist the court in determining:
• whether substance use is ongoing
• whether patterns of use exist
• whether further safeguards may be required in parenting arrangements
This may influence decisions regarding supervision, testing regimes, or staged increases in parenting time.
