Brief Answer:

Depends on how fast your hair grows.

Detailed Answer:

Hello,

Thc in general can be detected in the hair for after 90 days after stopping it in chronic users. Because, the hair test is the most accurate test.

But, depending on how fast the hair grows, if you have hair from 4 months ago, it would still show in your hair for up to 1 year.
This also depends on the technology that they are going to use.

So, I don't think that what you used just once 10 days ago it is going to be detected, but what you used 4 months ago still can be detected, even if a lower chance.

Hope I have answered your query.

Take care
