Can anyone recommend a hydrating scalp serum?

Hi all! I’ve been struggling with my scalp feeling tight and dry, both immediately after wash days and between, so I’m looking for a hydrating serum.

It doesn’t need to have hair growth or exfoliating benefits, but it’s fine if it has active ingredients for those purposes too.

Some I’ve tried and didnt enjoy were:

• Dove Scalp Therapy Fullness Restore Serum -> too fragranced
• The Ordinary Multi-Peptide Density Serum -> didnt really see results but also the purpose wasnt necessarily to hydrate

I’ve used scalp scrubs and rinses here and there, but havent found them really effective or to make much of a difference. The hair at my crown is thick so scrubs dont really get close enough to the scalp. Nothing I’ve added to my routine that would make a permanent change.
