  • ORIGINAL SILK THERAPY: In 1986, Farouk Shami researched & discovered the benefits of silk & how it could be used for hair. He knew that women wanted their hair to be shiny, healthy looking & conditioned. Silk solved these 3 issues with this one product.

    • Great product
Size: 12 Fl Oz (Pack of 1)
Best product for dry or damaged hair. Leave your hair looking silky, soft, and looking well hydrated. Too much product will cause your hair to look oily. I ordered a large bottle that will last for about a year.

    • Needed in a dry climate with strong UV exposures. GOOD dupe for Olaplex no9
Size: 5.64 Fl Oz (Pack of 1)
If your hair has been untamed and you live in a more dry and UV exposed climate, this product can help your hair behave how you'd expect it would in a less dry climate. Without the use of heat/gel/hot blowdrying tools. It can also provide relief from clarifying shampoos which affect your hair when you are in a more dry climate. Compared to Olaplex antioxidant serum no9, it is an ok dupe great for the value. It lasts longer than no9 if you have lots of hair. Less product is required than no9 for distribution. Though it makes no claims to protect hair from UV/free radicals like no9 it will help you get your hair healthier and where you want it in 3 months if you're trimming off your split ends periodically. It will weigh down more your hair than no9 and make your hair appear more fatty after the first day. Not a bad thing if you live in a arid-climate that dries out your hair. Certainly better than applying no protections or using a plant-oil for your hair inbetween washes. Unlike Olaplex no9 serum, the application lasts days, if you apply to damp hair after washing. It also has a higher viscosity that requires less amount and less applications post wash. It can save you between wash days. If you are not trying to dazzle with your hair down hairstyle on the daily and are ok with heavier/fattier appearing between washes. For example in a dry climate you might wear a protective style and a sun hat. It works very well for growing hair. The product has enabled me to grow out healthier hair, seal hair ends, and brush my hair with ease all week long. Where my hair was previously prone to daily tangling, split ends and dryness. A great product with great value. A small provision also last a while and the proce os ve ty reasonable. This product has been life changing for my hair. It is common for shampoos and washes to dry out hair, despite product claims to add moisture or body. In an arid climate, that simply doesn't apply. This product will leave hair manageable and helathier if used as directed (apply to damp hair after washing. Reapply as needed to dry hair to untangle and reduce frizz). ... show more

    • Great product, nitpicky observation
Size: 5.64 Fl Oz (Pack of 1)
Works well, one complaint is that when your hair dries and you touch your hair with wet hands, the texture of your hair becomes coarse and rough. This feeling goes away after it dries up. Very different experience compared to other hair oil. However, it smells great, my hair is soft, and feels amazing. ... show more

    • My All-Time Favorite Hair Product
Size: 34 Fl Oz (Pack of 1)
Love, love, love this! BioSilk Silk Therapy is hands down my favorite product for my hair. It leaves my hair feeling incredibly soft, smooth, and shiny without feeling greasy or weighed down. It really helps tame frizz and makes my ends look healthier, especially when I’m trying to prevent split ends. A little goes a long way, so the bottle lasts a long time too. And the scent… absolutely amazing! I constantly get compliments on how great my hair smells when I use this. If you want shine, softness, and that fresh salon scent, this is a must-have. ... show more
