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

I love this stuff!How I use it:Once I towel dry my hair, I brush it then split it into two sections, put a dab of the serum into each section, brush my hair again, then put my hair up into a bun and go to sleep. Curly hair in the morning.OR..In the morning when I want to straighten my hair, I brush my hair, split it into two sections, apply the serum, brush it again, spray heat protector through my hair, straighten my hair, then put a tiny dab of the serum through my hair one more time. This keeps my hair soft, smooth and the frizzes away.You can use it the same way if you're using a curling iron on your hair as well, keeps your hair from poofing out and looking bad.Overall, I love this product, maybe not so much the price, but I don't use that much and I make it last, however, my hair is fine, so I don't need that much.If you're looking for a serum to tame your frizz, give your curls a more smooth look, or wanting to keep your hair straight and soft all day, this is the stuff. Its not heavy, and you can get it on top of your head without it looking greasy. I freaked out when I first used it when I got a little too much on top of my head because it looked so gross, but I simply brushed it through a little bit, let it dry and it didn't look greasy at all. And I think the fragrance is nice, considering it not too overpowering like some hair products.I recommend every lady/guy try it and see how it works for them!

I have tried several hair serum's and this one hands down is the best. It is so silky - not sticky or smelly. You only use one or two pumps depending on how long your hair is. It's amazing what it does for shine and frizzy hair. It also makes my hair feel so soft and helps with damage due to blow drying. I had a hard time finding it so was thrilled Amazon had it. It lasts a very long time.

I have been purchasing this for quite a while now, and it has been a godsend to those of us with extremely curly hair. Couple quick pumps mixed in your palm of your hands and apply it to damp hair is what I do. I let it sit for a couple minutes and then I blow dry and fix my hair.It’s really nice and a bargain.

Love everything about this product. It smoothes my unruly, frizzy hair and it smells great. A must-have!

I have frizzy hair. I’ve tried a million products to try to tame it. Although there’s really nothing that controls it, this serum minimizes it and does so many other wonderful things to my hair like shine and softness. When I ran out of it, I definitely noticed a difference (for the worse) in my hair from when I did have it. Keep in mind, too much will make your hair look greasy. A little goes a long way.

Really happy with this product. Straightens and tames the frizzy ends. Leaves hair very soft.

Product does add shine & silkiness to gray hair. Only need to use a small amount for good results.

It works wonders for my hair. I love it!
