  • Worth Every Dime
Style: Silk Infusion Size: 6 Fl Oz (Pack of 1)
For those complaining about the price, I think it’s to be considered you may be using too much in your hair. You do NOT need a lot at all. That said, I am a 4c girlie with long thick hair and this had my hair so so soft and sleek. It felt like butter and smelled amazing. Silk press and blowout approved. A++ ... 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

  • The best product of its type that I've found
Style: Silk Infusion Size: 6 Fl Oz (Pack of 1)
CHI Silk Infusion is a total game-changer for my hair! This serum makes my hair super soft and shiny without weighing it down. It also helps with frizz and breakage. Plus, it's sulfate-free and cruelty-free, which is awesome. Highly recommend! I've used it for fifteen years.
