Silky & smooth hair in humid weather.
I have extremely long hair. This is the only product (and I’ve tried dozens) that keeps my hair silky and smooth without being greasy. Works fantastic in humid weather. A little goes a long way. Use in damp hair. Not wet or dry.

The best
I’ve been using this product for decades. Hands down, it’s my favorite hair product. It’s gentle on the hair, has no scent, and gets the job done. For the price, it is a generous amount and it lasts for a while. I tired other stuff but always come back to this.

Smells amazing! Great for hair and skin!
Have been using this since the 90's. Works great on mixed and Caucasian hair and skin. Love this on my skin before my Vaseline Coco butter lotion

A Classic for a Reason
This stuff is a classic. I’ve been using it for years, and it always makes my hair feel smoother, softer, and healthier. A little goes a long way, and it never disappoints. Definitely a go-to.

Thick texture but no heaviness, just shine
I was really surprised by the size of the bottle — you get a lot of product, and since you only need a small amount, I can tell this will last a long time. The smell is something I love, it smells really good and fresh. The texture is pretty thick, like a heavier oil, but once you apply it, your hair doesn’t feel heavy at all. That honestly surprised me. My hair tends to look dull, especially at the ends, and this made a big difference. I love how it brings shine back to my hair, helps with frizz, and even makes my split ends look less noticeable. The shine it gives is honestly impressive without making my hair look greasy. Overall, I love how my hair looks and feels after using this — softer, shinier, and more manageable.

Love love love!!
My mom used to use this on my hair as a child and the smell always stuck with me. As an adult i wanted to purchase it but it was a little steep for my pockets all to say i ended up buying it years later and i still love it! Now i use it on my kids they love the smell as well and it leaves their hair shiny, smells amazing, and moisturizes it! I definitely think the quality justifies the price if you have a little extra laying around! My daughters hairs are very coarse and dry as well as mine and well everything absorbs quickly but this just holds that moisture so well!

Indispensable pour mes cheveux
J’utilise ce Biosilk sérum depuis des années et je le rachète encore et encore. Il galbe bien les cheveux qui pour ma part sont texturés, leur apporte brillance et douceur, et je trouve qu’il fait exactement ce que j’attends. Pour moi, c’est un produit fiable qui ne déçoit jamais, idéal pour nourrir et embellir les cheveux au quotidien.
