Toppik hair thickening fibres and airports

Hope someone can help with this.

Ive recently been loosing my hair and I have been using Toppik fibres on my hair for it to look hide my problems.... And that's that.

I'm planning a holiday and will only be using my carry on luggage.
Id like to take my tube of fibres... But I'm concerned they might think if something more sinister.
Has anyone had any problems taking hair thickening fibres through customs at all?

Thanks in advance.
