Hair Drug Testing in Lake Forest
Walk-In Hair Follicle Drug Testing at Our Lake Forest, CA Facility
Hair follicle drug testing gives individuals and employers a detection window that urine and saliva tests simply can’t match. At Fastest Labs, we offer this service from our own physical facility right here in Lake Forest, CA, providing a certified, walk-in-ready experience with no referrals to third-party clinics.
The test analyzes approximately 90-120 strands of hair, 1.5 inches in length, collected directly from the test subject’s scalp. Because drugs are absorbed into the hair shaft as it grows, the sample reflects a record of substance use over the past 90 days. When body hair is used instead, that window can extend to the past year. Results are typically available within 1-2 days, and same-day drug testing is available when you need answers faster.

Who Uses Hair Drug Testing in Lake Forest
The 90-day detection window is what makes hair follicle drug testing the right choice when a brief recent-use test isn’t enough. Here’s who typically comes to us and why.
Employers with Zero Tolerance Policies
Pre-employment hair drug testing gives hiring managers a longer behavioral history than urine testing alone, which matters most in safety-sensitive roles across transportation, healthcare, and construction. We also support employers with policy creation, policy implementation, and ongoing program management, and we offer on-site mobile testing when bringing employees to our facility isn’t practical. Paired with a urine drug test, hair follicle testing provides a comprehensive, accurate look at drug usage across different time periods.
Legal Professionals & Court-Ordered Testing
Attorneys, courts, and government agencies use hair drug testing in child custody evaluations, probation compliance checks, and other proceedings where a multi-month history is required. The chain of custody process we follow at our Lake Forest facility keeps results documented and admissible from collection through laboratory analysis.
Government, Military & Student Athletes
We regularly serve military personnel requiring official documentation, government employees, and student athletes who need sports clearance, as well as individuals navigating immigration processes or court-ordered requirements.
Individuals & Families
Sometimes a parent or family member needs more than a recent-use urine test can offer. Hair drug testing provides a longer lookback that can offer clearer answers when they matter most.
What to Expect During Sample Collection
The collection process at Fastest Labs is straightforward and non-intrusive. Our certified collectors cut approximately 90-120 strands of hair, 1.5 inches in length, at the scalp. If scalp hair isn’t available, body hair serves as an alternative sample. The whole process takes only a few minutes in our sparkling clean facility.
After collection, the sample is secured and sent to a certified laboratory, where drug metabolites embedded in the hair shaft are identified. Chain of custody documentation is maintained throughout, which is essential for both workplace compliance and legal admissibility. Because metabolites are already incorporated into the hair shaft, short-term changes in behavior before the test don’t affect results. We offer 5, 10, 12, 14, 16, and 18-panel hair drug tests, and we can test for additional substances beyond standard panels depending on your needs.
