  • 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.
  • BIOSILK HAIR TREATMENTS: BioSilk has some of the most powerful and effective treatments. Whatever your style, we have a treatment just for you. Choose yours today.
  • HOW TO USE: Shake well before use. Place a small amount of silk therapy in your palms and apply from the scalp to ends. May be used on wet or dry hair or skin. Use as often as necessary.
  • BIOSILK: The quest for healthier hair is how BioSilk Silk Therapy emerged in 1986. The creation of the Original Silk Therapy treatment has led to the development of BioSilk Hair Color and a full range of hair products.

  • 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.

  • This should be my 4th bottle now!
Size: 5.6 Fl Oz (Pack of 1)
I’ve been using BioSilk Silk Therapy for a few years now, and I’m honestly blown away. My hair has always been on the dry and frizzy side, but just a few drops of this serum after washing make it feel silky smooth and look like I just stepped out of a salon. The shine is unreal, and it never feels greasy or weighed down. I also love that it works on both damp and dry hair, so I can use it for a quick touch-up before heading out. The scent is light and pleasant, and a little goes a long way, so the bottle will last a long time. This has become my go-to product for keeping my hair healthy, soft, and frizz-free. Highly recommend to anyone who wants that sleek, polished look without spending hours on styling! ... show more

  • Great quality, smells nice, and makes my hair very touchable!
Size: 5.6 Fl Oz (Pack of 1)
My mother turned me onto this stuff years ago and I still love it. You need a very very small amount so a bottle lasts quite a while. After washing and towel dry, I massage this into my wavy hair and it feels silky smooth and soft until I wash it again. It also smells really nice (but not strong or too much like perfume). If you have dry hair or split ends, you need to try this magical potion! ... show more

  • I love it!
Size: 12 Fl Oz (Pack of 1)
I have always struggled with frizzy and dry hair. I tried changing up my shampoo and conditioner and not putting any heat on my hair ever and I still couldn’t find the solution. I tried this and also used my hair dryer after and it changed my hair so much! This smells like a product from the salon and my hair is now so soft and frizz free! I am so excited about finding this product and can’t recommend it enough. ... show more

  • Needed in a dry climate with strong UV exposures. GOOD dupe for Olaplex no9
Size: 5.6 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: 5.6 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
