This is what the product looks like:
This is This is Cyclo-Dimethicone - another one of the products I got with my birthday gift certificates, and part of my exploration into becoming a cosmetics kitchenista...
I got it because I was looking for something cheaper than the name brands items (such as those with the word "silk" on the label). My niece, whose hair runs more to a Caucasian straight texture, wanted something to condition and add shine and smoothness. For me, with my nappy locks, I was looking for something to add softness and a nice sheen. We both got what we want - though my niece has to dilute the product to keep it from being too heavy as a leave-in.
This is not a big bottle but, like I said, people with straighter/finer hair like my niece will need to dilute this with a little water before applying. I didn't dilute, but I found it worked much better when applied to wet hair.
I don't know enough about the product to know why or how it works, but I do know that it does smooth down my hair and locked in some of the moisture left from my water rinse. It also felt wonderful.
When my hair dried, adding more of the product didn't really help with anything but adding a bit of a sheen. For finer hair, the product works as well or better than the name-brand "silk" type products.
Where things got interesting was when I used this on my skin. I applied a teensy tiny bit to my hands just to see what the effects would be. The product felt amazing, but I didn't think that it did much moisturizing by itself. When I added about 3 drops to a 0.5 ounce tube of hand lotion, I loved the effects. The lotion is a good, plain, well-known brand and very affordable. Adding this product to the lotion gave my simple hand cream a little bit of oomph. The lotion became silkier and a smaller amount seemed to spread better than before. Very nice.
Though I intended to use this primarily for my hair, I think that I like it better for use on my skin. Like I mentioned, a little bit boosted my hand lotion, but I was in love with its effects body wide. After a shower, I used some regular moisturizer, then I palmed about 3 drops of the cyclo-dimethicone, rubbed it in my hands to warm it and spread it over my legs and arms. I went back and read the product description and, wow, I totally agree with the parts I boldfaced below:

I might have to add some to the leave-in spray I threw together.
As far as how long this will last, I can't say. I think it will depend on what it's used for. If I were only using this for my hair, it would last a while. I tend to moisturize my skin more than I wash my hair, so... ~shrug~ I'll have to try to remember to let you know.
The only downside to buying these Making Cosmetic products is that they are not Prime eligible, and they cannot be returned. So far, I haven't wanted to return anything I've gotten from this seller.
