It's a 10 Haircare Miracle Styling Serum, 4 fl. oz.

I am an avid 'It's a 10' user. I am a platinum blonde and take my hair through a drill course every three weeks, so finding a product that puts my hair back into tip top shape is a never ending search. Until I found this product line. It is so hard to find the serum in stores, even in our local beauty store so I am so happy I found it online for a great price (cheaper than ordering through the beauty store catalogue.) I love all of the products, but I especially love the serum because it gives me a tangible product I can manipulate through my dry hair and ends and feel the smooth and silkiness while I am blow drying or just giving my hair a heat break and let it dry naturally. It cuts the dry time, and frizz time. And huge plus, it seems DEVINE. Everyone asks me why I smell so good and are surprised when I tell them it's my hair. So hopefully you are ok with complete strangers wanting a sniff of your beautiful hair! 4 oz. goes a long way as well, and lasts much longer than the leave in product sprays which is a big plus on the wallet. My mother snags this from me all the time (along with all my other hair products). It won't leave your hair greasy, even feels great on your skin and hands and will not weigh your hair down. I only wish it came in a bigger size.

I've been using this product for a few years, and this is the first time I have bought a replacement bottle. I originally purchased it at the salon in May 2011, and this small bottle lasted me over 2 1/2 years! And I used it almost every single day! You only need a small pea-sized drop for shoulder length hair, and it really smooths your hair and makes it super soft! I use it after blow-drying and straightening as a finishing smoother. It smells amazing too!! I usually have somewhat dry/frizzy ends, especially after blow-drying and straightening my hair, and I dye my hair too, so this really works well to help keep the ends smooth. Beware if you use too much, it will make your hair dirty and greasy feeling! I bought a bottle for my mom too and she has really frizzy/wiry hair and she is hooked on the stuff!

Great for adding shine and cutting down on frizz. I have unruly, naturally curly THICK hair that I could probably floss my teeth with. It gets FRIZZY in the summer. I first purchased this from an ULTA store in between meetings when my hair was out of control during a particularly humid day this summer. This actually calmed it down, after applying it in the car before heading to my next meeting. It has a lovely smell too.I find this product works best for shine and manageability if you use it on dry hair, before styling, especially if you are using a straightening iron. Nothing is perfect, but for the price, this definitely helps, and I can see a big difference when I do not use it.

This is the only product I have found that actually repairs the ends of my dry hair, especially my bangs. It's really easy to use too much though. A little goes a VERY long way, even on my very thick hair. I'm so happy to also have found a seller through Amazon that does not charge an arm and a leg for it. I originally paid $25 for it at the salon. I plan on being a regular customer.

My hair is always misbehaving - gets a lot of frizz no matter how much hair product I use. One of my niece has this and I tried it. The result was amazing! My hair stayed smooth and nice the whole day so I ordered my own bottle of this serum. No more bad hair day for me. My only complain is the pump - not working.

Absolutely the BEST hair product I have ever used! My cousin who is a hair stylist used this on my hair about 3 years ago and I can't say enough about it. I have very thick sandy brown hair...this product leaves my hair so straight, silky and shinny. Everyone asks me if I have a relaxer and are so surprised when I reply no. I love you It's a 10!!

What can I say." It's a 10" A great product. I use this every time I wash my hair and sometimes in between if needed. I love how it keeps the frizz out and leaves my hair soft and smooth. It is a little pricey but you get what you pay for in this case and it is well worth the money. Love it...

This is a product of used for years and love it! Glad to find it at a little bit of a discount on Amazon! If you have dry hair I highly recommend it

This product is super expensive, even when you get it at a great price on Amazon. It's about $48 in stores here in Ontario. I have a lot of hair and I find I need to use a good deal of this product to get the result I want. I'm going to have to see how I feel at the end of this bottle. I do like it, but I don't find it a miracle product just yet.
