Review: Shine, protection and best aroma - I’ve been using BioSilk Silk Therapy Original for years, and it’s still one of my go-to hair products. It leaves my hair feeling soft, smooth, and noticeably healthier without weighing it down. A little goes a long way, and it helps control frizz while adding a nice shine. It’s one of those products I always come back to because it just works.
Review: This should be my 4th bottle now! - 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!

### ⭐⭐⭐⭐⭐ Fantastic stuff!!!
*by A***. on May 25, 2025*

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!
