Most Helpful Positive Review Worth the money! First of all, if you think this product is greasy, you're probably using too much. I've been using Biosilk serum for 10 years now and I won't stop! I rub a nickel size amount into my palms and rub my hands together to warm it up. Then, I run it evenly through my hair when it's damp OR dry. It helps my dry hair feel soft and look shiny. It's a little pricey but trust me when I say, a little goes a long way. If you've tried the CHI hair serum, the results are similar to that but the Biosilk serum smells SO much better. You won't regret it!
Most Helpful Critical Review A little goes a long way Great for curly thick hair. My daughter uses it all the time. It's a little difficult to use due to its runny texture and it doesn't take much at all. It feels oily but doesn't feel that way after it dries on her hair. I have straight thin hair and it makes my hair look oily and limp

I struggle with a lot of frizz due to my curly, thick, frizzy texture and bought this hoping it would tame it. While it didn't directly tame my frizz, it softened my hair SO MUCH with less than a quarter size on wet hair. I finished it up with some on dry hair, and while there was still poofiness, my texture was SOOO soft and made it a lot more manageable. Smells strongly, but it's not an overt smell. For my type 3 hair ladies/gents, highly recommended!

cliche to say this item has been in my routine for a while. It has a strong fragrance but I love it. Recommend on wet hair to prevent frizz. It's a staple for a reason
Disappointed 2
KD from TN
I bought this product in hopes that it would be the hair serum to finally work on me. I have very thick hair that is always dry and frizzy with flyaways. Despite this product being on the pricier side, the same thing happens with this product as when I use cheaper products: my hair frizzes back up after a few minutes. I have tried using it both wet and dry and the result is the same. It has a nice smell, and it makes my skin soft, but I will not be buying the product again.

The GOAT 5

My mom used this on my hair 15 years ago and I still use it after every shower. I have very thick hair and I need about a quarter size but so worth the money.
Incredible 5
Sofi from Elko
Genuinely amazing. It is pricey but worth every penny. Makes my hair feel like silk and it's so shiny. A little goes a long way so a bottle lasts forever. MUST BUY.
Love this so much! 5
Annabelle from NC
This is the absolute best smelling stuff I've ever used and it's great for making my hair soft and manageable. Obviously if you use too much it will weigh your hair down and just make it greasy so use small amounts at a time and rub it through your hair thoroughly untill it's the perfect texture.
Tried and true classic 5
Jen from Texas
After trying other stuff I always go back to this. Best I've found. Smells great too. Pricey but a bottle lasts forever. Like literally a few years because you use such a small amount.
Not for me 1
Maddie from Florida
This is definitely not for thin, straight hair. All it did was weigh down my hair and make it smell really strong.

Mare from Detroit
I love this product so much. It's a staple and always leaves my hair super shiny and healthy feeling. I've been using this since I was a kid because my mom would always buy it. It smells amazing and a little bit goes a long way.

Marlene from Temecula
I love Bio silk.! Have use it for years, I have salt and pepper hair and Bio gives a beautiful definition to my hair color, very striking. I receive a lot of compliments on the shine. Will use it forever, have no desire change to another product. Also the consistency is not heavy on the hair and scalp, and the fragrance is not overpowering.
I would buy over and over 5

GET IT! from Atlanta, GA
I usually get wigs and treat them like my real hair. I couldn't figure out how my stylist got them so silky, I could never accomplish it myself so I finally asked her how she kept them looking new after several washes & she told me about this serum. I recently colored my wig again, used developer twice during the process and was nervous about the outcome because it can cause hair to get dry but nope! After using a good color-friendly shampoo and letting the conditioner sit for an hour, I blow dried (cold setting until barely damp) and used this serum while it was still wet. Once it was slightly damp, I sprayed with my Tresemmé heat tamer on the hot setting. Once it was all the way dry, I used another quarter size (20" length) over the hair then flat ironed. It turned out brand new again. I will be using this forever!
Love it! 5

I put it in my hair in the morning after shampooing my hair. I also use it at night for conditioning my hair over night. I love the way it makes my hair feel silky and not oily. It is like a dry oil. The smell is amazing and not overpowering

THE BEST 5
AshG from Suffolk County, NY
I have always loved Biosilk since years ago! It's a little pricey for the size of the bottle but it makes your hair feel so soft and helps with frizz. It also smells amazing
Love this stuff 5
Brooke from Ohio
None greasy if you only use a little. This stuff is amazing! I use it on mine and my daughters hair. Our hair is curly and thick. This maintains the Friz and makes your hair shiny and beautiful.
My only hair product 5
Sharon R from FL
I use a small amount of this on wet hair to prevent frizz on my straight highlighted 55 yr old hair. It works great whether I blow dry or just dry naturally! I'm not a fan of hair products, so I don't use anything else....I've been using this one for years.
A little goes a long way 5
Tokki from Splendora, TX
I love the formula so much, I've used so many other oils and conditioner to help my hair detangle and stay smooth, but they just don't hit the same like this one. I have extremely thick hair and I also have eczema, this is the only thing that doesn't make my scalp greasy and it doesn't irritate my skin, I bought the biggest bottle and I've had this for a few months and I barely made a dent in it. I highly recommend this product for those who have sensitive skin and have thick unmanageable hair. It's pretty pricey but it's worth the money and you don't need to use a lot of product
Misunderstood product!!! 5
OG from Georgia
I have seen a lot of reviews saying that this product makes their hair more dry or more brittle and I just want to say that before you use this product you need to understand how it works. This is not a moisturizing product. This product needs to be used in combination with other (high end) moisturizing products. Biosilk therapy is high in protein which will cause damage if not used with a good moisturizing shampoo and conditioner or some other moisturizing product. This product is made to protect hair, not to moisturize already damaged and dry hair. If your hair is damaged and dry you should be using good moisturizing products and adding biosilk on top to LOCK IN that moisture.
I love this product 5
Liv from Georgia
Let me start by saying I am extremely picky with the products that I use on my hair. With that being said, I already have very healthy hair that is long and thick but also fine. I have been using this product for years and even when I try something new I always come back to biosilk. This isn't a natural oil or anything so it can build up in your hair so I personally only use a small amount and I try to focus it on the ends of my hair to protect them. It tames any frizz I have and makes my hair soft. But I wouldn't say this is a "rescue" product for anyone with damaged hair though because it really won't hydrate your hair, it more or less just puts a nice coating on it which will help lock is moisture that is already there. IT DOES NOT ADD MOISTURE. this product is not to add moisture to your hair. If you have damaged hair you need to find products made specifically for damaged hair.
A "go to" hair serum.... 5
Alicat from Ohio
I have tried many serums, but this one I keep coming back to. I have thick, dry, fairly coarse hair with curls. This serum leaves my hair the shiniest and does the best job with being absorbed into the hair shaft as oppose to just feeling like it is coating it. And you do not need a lot, so the bottle lasts a long time. The scent is the BEST of all hair serums. I have allergies to scents and I can tolerate this one (I believe it tends to an essence of lavender). I really dislike the sweet, heavy, coconut and vanilla scents with a lot of the hair products out there. I have ditched trying any other serums at this point and am sticking with this tried and true product. This serum has been around a long time, so I believe that says a lot!
Good quality for me. 5

I like this product when the weather gets drier an day hair needs more moisture.
