Love the smell, how it feels on your hair, makes your hair shine and frizz free. Review: Fantastic stuff!!! - I used this product years & years ago when in high school & took a cosmetology class & it was used at the school off campus. I have an oily scalp but have highlighted & bleached my hair since I was 16 so the hair needs moisture to combat the damage. This serum is a miracle! I took a chance & looked for it some 30 years later on desertcart & here it is! It is just the best for untangling wet hair after washing without damage & without leaving hair weighed down & greasy looking! It's a leave-in so you don't have to rinse out & a little pea-sized puddle worked through wet hair is all you need. It is super slick for detangling with a wide-toothed comb but as long as you work it throughout your hair it doesn't dry to a crunchy state or goop up hair that is naturally oily & straight like mine. And when it drys, your hair will feel so soft & look so shiny and amazing without making it prematurely greasy. Oh, and it smells great too! ## Features - CREATES SMOOTH & SHINY HAIR: For centuries, silk was celebrated as a luxurious fabric due to its smooth texture & brilliant luster. This treatment was created as a weightless, leave-in silk replenishing formula to repair, smooth & protect all hair types. - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001797W40 | | ASIN | B001797W40 | | Active Ingredients | vitamin e | | Additional Features | Natural Ingredients, Not Tested On Animals | | Age Range Description | Adult | | Best Sellers Rank | #8,847 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #50 in Hair Treatment Masks | | Brand Name | BioSilk | | Customer Reviews | 4.7 4.7 out of 5 stars (16,265) | | Global Trade Identification Number | 00633911744147 | | Hair Conditioner Type | Leave-In Hair Conditioner | | Hair Type | Damaged | | Included Components | Active Substance Combinations | | Is Discontinued By Manufacturer | No | | Item Dimensions | 10.5 x 15 x 5.6 inches | | Item Form | Gel | | Item Weight | 5.64 Ounces | | Item model number | 0633911744147 | | Language | English | | Liquid Volume | 5.64 Fluid Ounces | | Manufacturer | Farouk Systems | | Manufacturer | Farouk Systems | | Manufacturer recommended age | 18 months - 8 years | | Material Features | Cruelty Free | | Material Type Free | BPA Free, Gluten Free, Paraben Free | | Number of Items | 1 | | Package Type Name | Bottle | | Product Benefits | Shining, Smoothening, Split Ends Repair, UV Protection | | Product Dimensions | 10.5 x 15 x 5.6 inches; 5.64 ounces | | Recommended Uses For Product | Shine | | Scent Name | Amber | | UPC | 885376771088 633911401033 885892172208 885401537894 885529336812 633911651223 633911747223 885376888830 | | UPC | 885376771088 633911401033 885892172208 885401537894 885529336812 633911651223 633911747223 885376888830 | | Unit Count | 167 Milliliters | ## Product Details - **Brand:** BioSilk - **Hair Type:** Damaged - **Item Form:** Gel - **Material Feature:** Cruelty Free - **Product Benefits:** Shining, Smoothening, Split Ends Repair, UV Protection ## Images ![BioSilk Silk Therapy Original, Reconstructing Treatment For Adding Shine & Helping Prevent Split Ends, Sulfate, Paraben, & Cruelty-Free, 5.64 Oz - Image 1](https://m.media-amazon.com/images/I/51AC6LwmJDL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Do you use this when your hair is wet or dry?
