Hair oil early 2000s

Does anyone remember this old hair product?”

Back in the early 2000s (around 2000–2005), I used to buy a hair oil/serum from Genovese or Eckerd or drug store. It came in a flat rectangular clear bottle (not round) with little shoulders, a ribbed light-blue twist-off cap, and inside was a thick clear oil/serum.

•	It smoothed frizz when straightening hair
•	Totally clear, no real scent
•	You only needed a tiny drop to work
•	I feel like the label might have said     something with “Silk” in the name

Does anyone remember what this was called, or have a picture of the old bottle?
