Definitely a straightening staple

All you need is a pea sized amount for past shoulder length hair. I use it on dry hair just before straightening (focus on ends and you can even use a tad after for additional shine). It's helped my hair maintain its health in-between trims. I usually don't blow dry my hair, but when I'm in a rush and need to, I run a little of it in my hair before doing so (don't add more if you're going to straighten after). I've had the same bottle for 2 years now and I'm not even half way done!

A great product for static

The Chi silk infusion oil is a great product if you have hair that holds a lot of static and gets a lot of fly away hairs. It is also great for cutting down on frizz. You need to only use a small drop though because if you use too much, your hair can get pretty greasy.

Smooth and sleek hair

This is an effective silicone type of serum that definitely smooths out frizzies and flyaways. I find it is quite heavy though so I have to use a very small amount otherwise my hair is super flat. It does give a very nice smooth and sleek look to straight hair and my hair is very shiny when using it. A little goes a long way, so although it is pricey, the bottle lasts almost a couple of years for me with regular use. There is a strong scent upon application but fades quickly.

This runs on the pricier side but it works wonders. I use it daily and makes my hair so soft and shiny. Absolutely recommend it! This also makes my hair smell nice

I got my hair done recently (straightening and cut) and at the end of a four hour long process, my hairdresser used this on my hair. Not only was my hair silky smooth, but it looked amazing. It had a nice shine and looked so much healthier. Everyone thought I had dyed my hair as well, but I had not. It really livened my hair up. Now I have to go out and get my own bottle.

This serum is a little pricey. The scent reminds me of mens cologne, but it's not repulsive. It leaves my hair feeling smooth and looking shiny. It doesn't make my hair look greasy nor does it weigh my hair down. I use this product in conjunction with a flat iron as a heat protectant.

Love it! Ideally I would prefer to find it on sale, because it is pretty pricey, but that being said it lasts a long time! Great for hydrating and protecting ends, I've tried a lot of other stuff but nothing quite compares.

Chi Silk Infusion runs a little on the expensive side so I at first purchased a travel size just in case it wasn't something I would like. Turns out I do like this product, a lot, and have since purchased the full size bottle. You will not need a lot of the product to get achieve shine, a little goes alone way!!! It has a beautiful smell that sticks to your hair after hot tools, rather then have a "burnt product" smell.
I find this serum to leave my hair so soft and shiny all day long! I mostly use this product on wet hair (roots to end) but i have tried it multiple times on dry hair without an issue(super thick hair); if your hair is fine you may not have as great results with the dry application as I did.

I love this product! I use it everyday. When my hair is wet, i run some through my hair with my fingers so that it comes out easily. Prevents a lot of breakage.

This is an expensive product so I always buy the travel size, but it's well worth it. It helps my color treated hair and smells amazing. One of the products I buy repeatedly.
