How to Use

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!
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 use this product after flat ironing my hair and it keeps it silky smooth. I love how my hair is shiny, stays fairly detangled that I can run my fingers through it, and smells nice.

My hair stylist uses this product every time I go there. When she put it on my hair get so silky, shiny but not greasy yet smells wonderfull. I finally got my own and now thinking why did I wait this long. Love love how my hair feels after. It is little pricey but you use little amount each time so The whole bottle will last you for so long. Forever buying this.

Roe from CO
I put a small amount in my hands and run it through my hair when I get out of the shower. It makes my hair so soft and it smells good too. I love this product and will continue to use it!

Just perfect and I use it for my hair

My mom has used this in my hair since I was 4 years old. I am now 22 years old with very curly hair (3b/c) and this is the magic secret product I don't tell anyone about! My strands are naturally baby fine and prone to breakage and this product helps strengthen my hair allowing it to grow massive! I never have to worry about split ends all while keeping my hair irresistibly soft, shiny, and frizz-free. For my curly girls, use this product with damp hair after your styling products with only the TINIEST amount. Your hair will thank you, I promise. Biosilk thank you for never changing the ingredients to this amazing product.
Tania from LA
I have very thick hair and this helped the frizz a bit but not enough to justify how much I used and the price to repurchase it so I ended up giving this to my mom and she liked it. Feels nice but not really worth it
Beth from Bakersfield, CA
I live by this. I have naturally straight hair but it tends to look a TINY bit frizzy sometimes. After a shower I let my hair air dry for a bit and then apply this when it's damp.
Using this makes my hair look like I used a straightener. Someone literally asked me if I straightened my hair one morning and I never straight my hair.
And it leaves my hair so incredibly soft!

I have always had thick and a lot of hair. I decided to dye my hair blond 3 years ago. After that my hair was distroyed I felt my hair would not grow, so a year and a half ago I started to usé Biosilk. After a shower I would put some biosilk on the tips of my hair. Then brush my hair out, I started to see results like 2 weeks after that. Since then I have been using this product, it has really helped my hair. Also if you hair is frizzy and follow this procedure your hair won't be as puffy/frizzy

I bought this for a friend who was helping me out to get free shipping. It's something she always uses.
Sam from Connecticut
This product did absolute WONDERS to my hair. But it broke my forehead and hairline out so badly. I wish I could keep using it because it is probably the best hair product I have ever used, but it caused the worst breakout I've ever had on my forehead.
Shannon from Dallas Texas
My hair is fried from going blonde so often, but usually it bounces back quickly. Well after going the lightest I've ever been in September 2019, I decided to take better care of my hair. I bought bio silk because the description made it seem like an awesome reconstructive solution that would help the damaged appearance while fixing it. I also swore off heat products, and only got baby lights to blend my roots a little in January. Aside from that I've just been extremely gentle with my hair, used hydrating high end shampoo and conditioner....and biosilk. I noticed my ends continued to be like straw so I cut 6 inches off and spot cut all my split ends. So I was beyond surprised when not too long afterward my ends once again felt like fried straw (because prior to my use of biosilk my hair always bounced back well!) After 7 months of deliberate care and use of biosilk, you'd think my hair would be soft and shiny as they advertise. Instead my hair is dry, brittle and breaking. Wasn't till I read reviews on here that made me realize it's the biosilk I've been using religiously. Maybe it works well on uncolored, natural hair, but use caution before using this to repair your damaged hair.for me it made it much worse.

My mom started using this on my hair when I was 3, because she couldn't get my tangles out any other way. I have very fine hair, but a lot of it. To this day, I can't brush my hair without biosilk. I'm in my 30's. I use this every time I wash my hair, just a few drops, and massage the excess into my hands. I apply mostly at the ends of my hair and run just a little up to the roots. If you apply too heavily, your hair WILL look greasy. One big bottle lasts me 1.5-2 years. I will never stop using this!

I use this when I get out of the shower. I put some in my hands and gently put it on my hair -- note I said 'on' not 'through,' I don't finger comb this, i kinda use the 'praying hands' method of applying it gently. You need to remember to do it when hair is still wet.
Mujmm from St. Peters
Been using this for years. It makes my dry, curly hair feel soft and smooth. Would definitely recommend!
Stephanie from Los Angeles, CA
This is one of the first "hair oils" that came out back in the day (90's?) and I have been purchasing pretty consistently since then. I have, of course, tried many high and low end alternatives over the years, but have never found one that I think is markedly better than this one. Given how much product you get, this stuff is pretty darn affordable and it just works. I use in in damp hair before heat styling and I notice a marked difference when I use this before heat tools.
ek from il
i was excited and i had just used it but then i started reading the ingredient list and 3 ingredients down i see denatured alcohol... this is an extremely drying agent at high concentrations. i'm afraid that if i keep using this it will be extremely bad for my hair health
RO from New York
I use a small amount prior to drying hair work it thru hair. Any areas that look frizzy once dry I apply a tiny amount.
chezmp from Iowa
make sure to use a good moisturizing conditioner. it's very high in protein and too much protein can be damaging resulting in dryness. I found out from trial and error and I'm protein sensitive but I'm able to continue to use this knowing a can counterbalance with my moisturizing conditioner
AJ from Oregon
I am an on the go professional and work long hours. This product does wonders for my hair and lasts all day. My favorite hair care product for healthy, shiny hair.
Nikki from West Jordan Utah

She beast from Corning, ny
up it it in my wet hair, whether I sit dry or use a dryer it is always silky and soft. I have grey hair too.
BornAUnicorn from USA
This stuff is expensive but totally worth the price. A little goes a LONG way so the bottle lasts a long time. I use it after I straighten my hair and it always makes it look healthy, shiny and omg soft. It smells freaking amazing too! This serum is Godsend.
