Some beauty products come and go with the trends. Others stick around for decades because they work that well. BioSilk Silk Therapy Original<\/a> falls into that latter category, and right now it\u2019s 72% off on Amazon.
This leave-in treatment debuted in 1986 and today it\u2019s still praised by shoppers. It smoothes frizz, adds shine to hair and helps prevent split ends, and it works on all hair types, including color-treated hair. With the major price drop, it\u2019s a good time to try the product your mom (and maybe even your grandmother) swore by, or to stock up if you already love it.
BioSilk Silk Therapy Original<\/a> is a leave-in treatment that has been on salon and bathroom shelves since 1986. Its formula uses silk proteins, and it\u2019s designed to fill gaps in the hair cuticle so strands look smoother, shinier and less frizzy, according to the brand. It also helps prevent split ends and breakage. The lightweight treatment works on all hair types, including fine, curly, textured and color-treated hair. It\u2019s sulfate-free, paraben-free and cruelty-free.
Based on reviews, it also works across all hair types. One shopper wrote<\/a> that their daughter\u2019s 4C curls had been damaged by high-heat styling tools, and after a stylist used Silk Therapy on her, they \u201ccouldn\u2019t believe how healthy her hair was after one use.\u201d Another reviewer<\/a> who said they have thin, damaged hair wrote that the treatment gave their hair \u201csome weight and [it] looked thicker, smoother, and shinier.\u201d At this price, you can stock up for yourself and also grab a few as stocking stuffers so the whole family isn\u2019t using yours.
