Not for dry hair
I bought it last year, but can't use it because it is very light for my dry, bleached hair. I think girls with fine hair would like it.

Was sadly disappointed. Very strong scent
I basically spent one of my nights off perusing sleekhair for new products to try out since I'm a girl who loves products and all the pretty packing. Anyhow, I came up with a list of the top rated items I had yet to try and on a whim, I purchased a few of them! I am a religious review reader and writer so i appreciate when people take a few moments to reflect on their likes and dislikes as I really use them to guide me in my purchasing. In this case, i find this product was a MISS :( It has a very intense (and to me,unpleasant) odour. It is an oil product and not like a dry oil that readily absorbs into your hair, it is very greasy and a disaster to work with. Additionally, my bottle must be defective because it leaks like a tap! I made the mistake of bringing in my suitcase without a ziploc bag and mild disaster ensued. It stained one of my white shirts, which only leads me to believe that it can stain your clothes if you accidentally forget to wash your hands thoroughly after you get ready! I also didn't find it did any of the miracles other reviewers felt it did. Overall I rate this a D-
ConsStrong unpleasant odour Extremely greasy and heavy Stains clothes

Great shine
Great shine but definitely ran out of product fast. Not enough product for price. Fragrance is strong, but creates a nice shine.

Not for fine hair
I have fine hair and this serum is wayyyyy to thick for me. There are so many other much better and light oils on the market right now that give shine without making hair greasy.

Why does this product work so well? It's so small and pretty expensive!

DO NOT BUY THIS PRODUCT! It STINKS!! Not only does it contain alcohol, which dries the hair out, it smelled like an old man's cologne. I ended up leaving this product in a cart at WalMart. Whoever found it was more than welcome to this!!! I will NEVER purchase this again!! Save your money. Get Lanza Serum or White Sands.

You don't need to use much, just a couple of drops. It's not greasy (like other oils I have tried). It's great for smoothing and detangling.

The price of this product is well worth the result. i have been using the cristalli liquid for several years. i have very fine hair and live in an extremely humid climate. this product keeps my hair smooth, soft and manageable all year long without ever making it feel heavy or greasy. I love this stuff!

I noticed the size of this product is soo much smaller than other serums. How long does the 1.69 oz. size last you girls? I have medium length hair that is pretty coarse.

I have 20-inch extensions. I use two pumps daily to run it through my hair prior to brushing. I use about 10-15 pumps when I wash my hair to make it easier to use a round brush. I think my oil lasts several months. The largest bottle lasts me about 4-5 months. I have tried all different oils and I always come back to this one. It is the least greasy out of anything I have tried. I highly recommend this product.

A little bit of this product goes a long way. Do not over-use as it will make your hair oily, especially the day after. I have very course hair as well. I use it on my wet hair before I blow dry. The smell is incredible (honestly, that why I use this!!!)

That depends on how often you wash your hair. If you use no more than a tablespoon, which is plenty, on your wet hair everyday after shampooing, it should last you about 2 months. I have very long hair, so I need twice the amount needed for medium length and it lasts me more than a month.

This size product can last me from 3 to 5 months depending on how often I wash my hair. My hair is also of medium length and course and I have a lot of it too. First I let my hair air dry before blowdrying for 5 minutes. I use 2 to 3 drops of serum on large sections of hair before flat ironing each section. It is completely non-greasy and makes my hair silky, shiney and soft. I've used it for the past 4 years when it was first introduced to me by the hair salon that does my Keratin treatments. I absolutely love this serum and wouldn't be without it. A little goes a long way.

I have long hair and this goes with me for 8-9 month because you need really so little of this. 1 pump on all hair
