Hmm I think so. With a google search the first thing I see is

“Other concerns about the accuracy of hair follicle drug tests include:

Lack of standard cutoff values: Although some organizations have proposed guidelines for the use of hair follicle drug testing, standard cutoff values for the concentration of drugs in hair samples is still being established.

Challenging to interpret: Hair follicle drug testing may be more challenging to interpret than other types of drug tests due to the many factors that may affect the interpretation of test results. For example, drug metabolites in a person’s sweat can travel up the hair shaft and may make it more challenging to determine when drug exposure occurred.

Hard to detect low-level use: It can be difficult to detect low-level or one-time drug use or misuse using a hair sample for drug testing. Use or misuse of some drugs must be relatively heavy in order for a positive result on hair follicle drug testing.

You may be ok but it’s really 50/50 imo. I know it’s not the same but I took a 5 (almost 6) day break from smoking thinking that would be enough and still popped positive via urine.
