I love love love BioSilk! When used daily, it does an amazing job at fixing split ends, ending frizziness, and improving the overall health of my hair. I apply this product when my hair is wet and I want to wear my hair straight, not curly. (Although, sometimes I will put on a little bit when I am letting my hair be naturally curly, to cut down on the frizz.) There is only one reason I rate this 4 rather than 5 stars, and that is because you have to be very careful not to put on too much. If you put on too much BioSilk, your hair will feel oily/greasy (which is never good!) (This is also why I apply it while my hair is wet.) Remember that a little goes a really long way when it comes to this product. Just dab it lightly on your hair.

This product can be used by everyone! It is a hair serum that helps de-frizz your hair, or soften your skin. I love this product because I think it works better than any other anti frizz serum I've found. It has a lovely smell, and you don't have to put a lot in your hair to get results. I use it when I straighten my hair and when i leave it curly to control frizz, and to give my hair a soft, silky smooth look and feel to it. You can use it as often as you'd like, keeping in mind to only used a dime sized amount, to avoid greasy looking hair. This is still a serum, and if you use too much your hair will end up looking greasy, and you wont end up with the look your going for. I have used this product many times, and would highly recommend that anyone looking to help control frizz try's it. Usually you can only buy the larger bottle, which comes with a smaller "travel" sized bottle. It should only cost you around $20, and is available at most salons.

This product is great if you frequently use lots of heat to style your hair which, as we all know, causes those nasty little fly-aways on the top of your head. My hair is curly so when I use a blow-dryer to make it straight I need some something to take away the frizz as well as add shine. This product is amazing because it does both of those things, strengthens your hair and it smells great! A friend of mine also has curly hair but hers isn't as thick and she says that it weighed her hair down. So caution to those of you who have fine hair, this product is oil based and may not be for you.

i bought this recently. and the few times that i have used it.. i have not been disappointed. you only need a small amount.. AND i have no more split ends. i had tons of split ends.. now i dont have any. i am quite pleased about that. :)

my hair is really dry, and frizzy after showering, and drys. and thats why i have to flat iron it all the time. so my hair is super damaged, but after using this product, i can see a big difference in the way my hair, feels, looks, and drys, after showering.

it used to poof out, and look ridiculously ugly, now its normal looking.

kinda expensive though.. but in the long run.. i think its worth it.

I have been using this for years. However, after trying Moraccan Oil, this product now is in second place for me. Biosilk seems synthetic even though it gets the job done.

Although my star-based rating is mediocre at best, I will admit that this product is, in fact, tremendous. Coupled with the strength of heating tools, it absolutely delivers "the luxury of silk." Still rumors suggest that this product strains and damages the condition of hair, straying from the ideal of naturally luscious locks.

This is one of those products that is worth every penny. It makes bad hair days a thing of the past. My hair feels amazing after using this product.

I'm upset with this product. I've been using this for years (extremely rare for me because I always bounce around from product to product without sticking to any one thing) and I thought I loved it. It smells great, you only need to use a tiny bit, and it seems lightweight. But about a month ago I got a haircut and the stylist was commenting on how weighed down my hair is and asked what I used. I told him I was using Silk Therapy and he literally recoiled in horror. "Oh no!" he said "That stuff turns into grease in your hair!". At the time I scoffed at him but now...I think he's right. For reference, I'm half black half east indian with very curly type 4A hair. I used to relax it but I stopped about 2 years ago and now just wash once a week and blow it out straight. I either wrap my hair at night or tuck it into a satin cap and you know what? About 3 days after I wash it my hair is grease-mania. It's so lank and flat and lifeless. Looks nice and shiny and is soft and smells good. But it's so flat and greasy. I'm wondering if the combination of using small amounts of Silk Therapy about every other day and keeping my hair wrapped at home is just giving it too much moisture. Either way, I think I'm going to have to start looking for an alternative because this is just not doing it for me anymore. I'm sad though. I really thought I loved this stuff.
