I have been using Thymuskin for some time, but because of my very fine hair I need a mousse and hairspray. Can I still use both?

Yes, this is not a problem, as these are so-called "finishing products" that are applied after the Thymuskin Serum has been applied.

However, please ensure that you wash your hair before applying Thymuskin Serum again. As there are residues of mousse and hairspray on the scalp, there is a risk of massaging these into the scalp together with the Thymuskin Serum, which can lead to skin irritation.
