Pumpkin seed
One randomized, placebo‑controlled trial found men taking oral pumpkin seed oil capsules had a meaningful hair‑count gain; animal studies and small topical trials add plausible mechanisms but do not settle whether rubbing oil on your scalp will help. Evidence is suggestive but thin and largely unreplicated.

Face oils
The idea that 'linoleic oils are better for oily, acne-prone skin' rests largely on small lab studies and a few pilot clinical observations; the literature here is promising but mostly preclinical and frequently tests oils inside blends or nano‑formulations.

Rosehip
Lab and animal work plus a few formulation studies point to plausible ways rosehip might influence pigmentation, but direct human evidence that rosehip oil by itself fades dark spots is very limited.
