Is real mulberry silk worth the extra money over satin?

Across the reviewers we read, the consensus is yes for hair and longevity: specialist subreddit threads in r/beauty and r/BuyItForLife report that polyester satin tends to pill over time while 100% mulberry silk softens with washing. However, multiple community reviewers also note that satin delivers a similar cool, smooth feel at a fraction of the cost, so if budget is the constraint, satin is a legitimate entry point.
