Product Description

This quest for healthier hair is how BioSilk Silk Therapy emerged in 1986. For centuries, silk was celebrated as a luxurious fabric due to its smooth texture and brilliant luster. Throughout history, silk clothed royalty and the elite, continually evolving with fashion trends to be one of the most coveted fabrics of all times.

The launch of BioSilk Silk Therapy was yet another first since natural pure silk had never been used in hair care before. It was created as a weightless, leave-in silk replenishing and reconstructing treatment to repair, smooth and protect all hair types.

BioSilk Silk Therapy continues to be one of the company’s strongest product offerings, winning countless beauty awards throughout the years, and is recognized brand among 97% of women.

How to Use

Shake well before use. Place a small amount of silk therapy in the palms and apply from the scalp to ends. May be used on wet or dry hair or skin. Us as often as necessary.

    I’ve been using this product for years. I love it. It makes my hair soft and shiny and so much more manageable. A little product goes a long way so it lasts a while.

    I have been using the Biosilk therapy original for over 25 years! Yes! 25. It leaves my long hair feeling silky and looking healthy. And a little bit of product goes a long way 🙂

    So in love with this product, it is absolutely amazing!

  5. Ashley (verified owner)

    I have very curly, frizzy hair and this product works great! It makes my hair super soft and minimizes frizz. It’s expensive, but it lasts a long time, so totally worth the splurge.

    Great value for money a lil but last a long time!

    My friend introduced me to BioSilk Silk Therapy years ago. I am continually amazed how much it protects my hair. Normally my hair gets so frizzy while being blow dried, but just a bit of silk therapy protects it. I don’t have to straighten my hair if I use silk therapy!

    Biosilk original silk is my secret for silky bleach blonde hair.

    I have been using Sunglitz for years. I absolutley love it. I have been trying to find it under that name with no luck for months. With a little investigating came across Biosilk, same company. Ordered it. And it’s the same thing. I could not be happier. Please never stop making this.

    I have been using this product for years. It is fantastic for hair and skin. You don’t need to use a lot so the bottle lasts a long time. Great value for money.

    I have been using this product since almost very first came out. I was In my girlfriend’s beauty salon and a guy came in and showed us the 3 pack shampoo conditioner and leave in conditioner. I bought two of those 3 packs. I absolutely loved them. She got them a few more times and then she couldn’t get them and I couldn’t find them anywhere. For 2 years I looked and then I finally found them in JC Penney. I bought it there for a few years Religiously.The closest JC penney Was almost 2 hours away and I went just to get it a few times. Most the time I was up there anyway but there is a few times I went up specifically for my biosilk. I don’t remember where I got it after JC Penney close in that mall but I have started buying it in salons and it has been the absolute most amazing thing that’s happened to my hair. My hair is thin And a very fine. Since all Or most of the salons have closed because of covid19. I’m now here going to order some because I think probably since that first time in my girlfriend salon has probably been about 22 years and I don’t use anything else on my hair it is fabulous.

    Biosilk Therapy is the only product that takes my hair! It smells great, defines every curl, and adds support all day long.

  17. Connie Turner

    I have been using this product for over 10 years. I love it! It helps reduce the frizzies and keeps my hair smooth and much more manageable. I was really excited to find it on Amazon as I had not seen it in the beauty salon or Beauty Supply store for a while now. I was almost out when I found it. Yeah!

    I have thick, wavy, FRIZZY hair. About six or seven years ago, the lady that cuts my hair introduced me to Biosilk and explained to me that I was over shampooing my hair type. It has completely changed how I think of my own hair. I freakin’ LOVE my hair now. I use to think it was ugly and dry looking. Now I get compliments on my hair on a regular basis. A little bit goes a very long way.

    My hair routine is now wash, condition, towel dry, put in about a quarter sized amount of biosilk, scrunch it around a bit and move on with my day. The waves have better shape and the frizz is almost entirely gone. I haven’t had problems with split ends or hair breaking since I started using it. It will be a very dark day in my world if they ever stop making this stuff.

    I have always had trouble with my dry curly hair. I have tried so many different products over the years I am 45 so u can try to imagine the money that I wasted trying expensive products. About 7 years ago I tried Biosilk Silk Therapy and it changed my life, will never use anything else ever again! And having to daughters both with very long hair, they both love it also, you can only imagine how much we go through. Thank you for an awesome product, it’s the only thing I have used since I discovered it all those years ago!!

  20. Ronnie

    I absolutely LOOOOVE biosilk.. I don’t think I could live without it. I paid 56$ per bottle of shampoo and conditioner of pureology and biosilk is by far in the lead, and more affordable 🙂

  21. skyee

    I will probably use this product for the rest of my life. I am blown away by how soft my hair is after one little squirt of this stuff. A little definitely goes a long way, and I am just too happy with this find.

    Amazing! I have been using Biosilk original therapy religiously for 9 years, I was able to buy it at my local stores, but then they quit carrying it.
    I then tried buying it on Amazon twice for $21 and it was thick and greasy … I guess the saying you get what you pay for is true.
    Finally out of desperation ( my skin and hair felt dry) I googled and found the Biosilk website. Yes it is more costly than other places but Wow It is Amazing! I got this yesterday and I already notice a difference using it after my shower last night.
    I will Never go without the good stuff again. It can literally shave 10 year off your age if you use it everyday. I put a light layer on my face and neck in the morning and before bed. It is not great and does not cause breakouts.

  23. Travis Porter

    This stuff has been my go to since growing my hair out. I have used BioSilk for about three years now and haven’t found a product that even compares to this. As a guy with long hair it does exactly what I want it to, it keeps my hair from getting all tangled and keeps it looking healthy and manageable.

  24. Shanette Bergener

    I’m a hairdresser and have recommended this to my clients for almost 20 years! Even cheaper than the beauty supply. I definitely can tell who used this and who doesn’t. It not only treats but prevents breakage. It’s best to use a small amount on the mid-shaft to the ends of hair. I always use this on a color before I do blonde typo prevent damage from coloring. I love this product!!!
