  • 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

  • Soft silky shine
Size: 5.6 Fl Oz (Pack of 1)
Works wonders! It saves my hair when I have it blown out and keeps my ends from becoming damaged. Gives a beautiful soft silky shine that feels high quality. Last for months and is well worth the price.

  • worth the hype!!
Size: 2.26 Fl Oz (Pack of 1)
WORTH THE HYPE. This stuff is amazing and you only need a *tiny* amount of product. Leaves hair frizz-free for DAYS with no need to touch up. Feels weightless and natural, like you have nothing in it at all. Very light scent that's very clean not overpowering. Will definitely be buying this for the rest of my life. ... show more

  • Soft and shiny without looking greasy
Size: 12 Fl Oz (Pack of 1)
⭐️⭐️⭐️⭐️⭐️ Shiny, Soft, and Frizz-Free! I love this product! My hair tends to get frizzy and dry, but BioSilk makes it feel silky smooth and look so much healthier. A little goes a long way — just a drop or two keeps my hair soft, shiny, and manageable all day without looking greasy. The scent is light and pleasant, and it works on both damp and dry hair. Definitely a staple in my routine! ... show more

  • Fantastic stuff!!!
Size: 5.6 Fl Oz (Pack of 1)
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 Amazon & 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! ... show more

  • Good product
Size: 5.6 Fl Oz (Pack of 1)
It’s a good product that leaves hair shiny and smooth, but you only need a very small amount otherwise it can make your hair look greasy. A little goes a long way!

  • BioSilk Silk Therapy Serum for Hair
Size: 2.26 Fl Oz (Pack of 1)
Absolutely love this Biosilk silk therapy hair serum! Out of all of the products I have tried, this one by far works the best!!! It leaves my hair feeling hydrated, silky, and less frizzy. It's super lightweight and helps my curly hair resist tangles. I love this smaller bottle so I can take it with me while traveling. Definitely a great buy and definitely worth it! ... show more

  • Really good, hydrates and protects, smells great
Size: 12 Fl Oz (Pack of 1)
Really good, smells great, but it is a little greasy. If you have thin hair, it's gonna make it even thinner at first. But it does a really good job keeping hair from drying out, and I live in a very hot and dry area. It's lightweight, and a little goes a long way.
