  • 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

  • Great For Straightened Natural Hair
Size: 2.26 Fl Oz (Pack of 1)
This product smells great. It made my hair feel moisturized and look shiny. The bottle says you can put it on your skin as well. I have straightened 3c/4a and I needed a moisturizer that wouldn’t make my hair revert to curly. This seems to be doing a good job so far. I suggest you get the smallest size first to see if you like it. I ordered the 2.26 fl oz (smallest) bottle to see if I liked it and this bottle will still last me at least 6 months! ... show more

  • Terrific Product
Size: 5.6 Fl Oz (Pack of 1)
My hair is baby-fine and long. It likes to tangle on the bottom and break off. A bit of this rubbed into the ends of my hair after every shower is a miracle. No more breaking, split ends. The only downside is the slight fragrance, but it's at the bottoms of my hair away from my nose so I can tolerate it! I am using this for the rest of my life. ... show more

  • Fights an epic battle against my evil frizzy, coarse, textured hair!!
Size: 5.6 Fl Oz (Pack of 1)
5 stars! OBSESSING! I FINALLY HAVE SOFT CURLS!! & LESS FRIZZ! my hair is a very special kind of evil and feels very coarse and full of frizz. I'm neurodivergent and it is a nightmare to have hair that is textured that way so before this, I usually would end up heat styling to straighten it. I don't have to do that with this product. Oh!! Did I mention the terrific smell?!!! Amazing!!! If you have product left on your hands you can use it on your skin! ... show more

  • Inexpensive Serum Works immediately
Size: 5.6 Fl Oz (Pack of 1)
I have been using so many different Hair products that it has become exhausting. I just don’t even wanna try anymore. I’ve paid so much money to be left Disappointed. I didn’t think This inexpensive product Would live up to the reviews. I am very surprised at how little was needed for my very long hair and how instantaneously my hair texture changed after applying. My hair became less tangled and silky soft. I will continue to use and look forward to living the rest of my life with frizz free manageable hair!!! ... show more

  • Not the real one.
Size: 5.6 Fl Oz (Pack of 1)
This is not the real Biosilk serum: - Please check the 1 star reviews, the product description picture doesn't match the one I received at home. It actually says " for body and hair". I have the original Biosilk serum old bottle and it doesn't say that. - Second, it's a terrible product. The real one seals and repairs your hair instantly. This one left my hair feeling greasy and dull. I really want to believe this is a counterfeit, because if you reformulated this amazing formula. You've clearly failed! ... show more

  • The shiniest I've ever seen my hair
Size: 5.6 Fl Oz (Pack of 1)
I have thick coarse hair that likes to stay frizzy and dry. I've only used this product one time but when my hair was dry I looked in the mirror and my jaw dropped. It was the shiniest I've ever seen it. It felt so luxurious. Unless that was beginners luck, this product will stay in my regular hair routine for a very long time. ... show more
