  • The best
Style: Silk Infusion Size: 6 Fl Oz (Pack of 1)
I don't know why I ever stopped using CHI products. I forgot about the great quality, in this non greasy oil. Leaves my hair very soft and manageable. He hair feels hydrated and healthy.

  • Great product
Style: Silk Infusion Size: 6 Fl Oz (Pack of 1)
I was having issues with my hair always feeling dry (I am on well water) I read reviews on this product and used it for the first time. I followed the directions and put some in my hand, ran it through my towel dried hair. I did find my hair took a bit longer to dry, but it is so soft and silky smooth. I highly recommend this product to get your hair soft/smooth. ... show more

  • MIRACLE IN A BOTTLE
Style: Smoothing Treatment Size: 3.92 Fl Oz (Pack of 1)
I recently cut my 2c coarse frizzy hair eleven inches. My hair now comes up to my shoulders and looks like a triangle bob when curly. Stupid me thought I could iron it every day. Dumb idea. After a month of ironing/blowdrying my hair every other day (with heat protector), my hair lost ALL its shine and barely holds a straightening. I didn't want to spend $300 on a permanent salon straightening, so I looked into many different options. It came down to an at-home keratin straightening with a full kit or this. I decided to try this, as it didn't seem nearly as harsh as the other one; I was scared an at-home permanent straightening could make my hair fall out. This seemed pretty idiot-proof :) ~EXPECTATIONS: Most of the reviews seemed to suggest that this was the miracle in a bottle I was looking for, but I was a little skeptical. It was only sold on Amazon and the Chi website, and I couldn't find reviews anywhere other than Amazon, which was both a little odd to me. No Youtube reviews or beauty blog posts on this product. I expected: 1) Softer silkier hair - due to the keratin 2) Straightening with flat irons and blowdrys that last longer 3) Heavier hair - also due to the keratin :) Keratin builds up on hair and can weigh it down, so I did buy a clarifying shampoo to go with it. ~HOW IT WORKED FOR ME: Holy cow! This was AMAZING. It did everything I expected, and more. I put it in freshly washed, mostly dry hair, even though instructions say to use it on damp hair. I also used a LOT, putting on each section of hair as I blew it, and my hair didn't feel heavy at all. As soon as I blew it, I noticed a massive difference. Firstly, it was baby soft! It was like different hair. Second, it made blowing my hair ten times quicker, and my hair didn't get as puffy as it normally did. I didn't even need to iron it, but I did, mainly because I wanted it to last at least 3 days (to minimize heat use). The only 'bad' thing about this is that it smells a little like soap, but its very faint. To people wondering if this protects hair from heat, it doesn't. It's a treatment, not a heat protectant - I used a heat spray after blowing/before ironing. This works great in humidity, terrible in rain (duh). The longest I've gone without washing it out was 5 days, and I only needed to touch up the ends once, but beware of oily hair *-* I use this now twice a week, and it works amazing. If your hair starts to feel greasy after a few uses, it's normal! Keratin is a great protein for hair, but too much can weigh down hair, especially fine hair, so make sure to incorporate a clarifying shampoo into your routine. ~PRODUCTS I USE: Shampoo - giovanni tea tree triple treat shampoo (clarifies and removes buildup) // Conditioner - aussie miracles moist 3 minute deep conditioner // Heat Protector - tresemme heat tamer spray // Leave-in Conditioner - garnier fructis curl air dry cream ... show more

  • Worked wonderfully!
Style: Smoothing Treatment Size: 3.92 Fl Oz (Pack of 1)
I live in the Deep South and humidity is horrible. I also have fine hair that’s consistently dyed and bleached every seven weeks or so. I’m always looking for products to fight humidity and to also stop my hair from being so dry from the processing. I bought this a few months ago and finally tried it a few days ago. I can’t believe it actually worked. It made my hair feel smooth and silky, no dryness in my ends and kept it sleek even after sleeping on it and through the humidity that has come with all the rain. It might only last a few days at a time but you can’t expect it to last for weeks. I highly recommend it. ... show more

This product did help to tame my frizzy hair. However, I literally had to use it everyday and then my hair felt weighed down. I think WOW’s Dreamcoat works better.
