Not likely.: Marijuana can remain positive in drug screens up to a month and in the hair follicle for about three months but if you have only done random hits the amounts maybe too small to show up.

OOps, I missed the fact that you had daily use in January. In that case, I agree with Drs. Fowler and Husar. You may not pass. Sorry for misunderstanding.

May not: In “pharmacokinetics of cannabinoids” by mcgilveray ij it is stated “hair tests are more likely to detect regular than occasional marijuana use. One study found that 85% of daily users tested positive for marijuana, versus 52% of occasional smokers (1-5 times per week). Since you used regularly until end of january - you may not pass.
