Great product and value!
Great product and value, this bottle will last me 6 months and I've got very long hair. Not greasy, only need a small amount. Transforms my dry hair and smells fantastic. Love the way my hair looks, feels and smells when I use a dab of this.

Excellent hair serum! Recommend.
This hair serum is amazing! Leaves my hair soft, silky, reduces frizz, fly-aways, and it has a pleasant scent. You don’t need to use much to get results. It also helps to reduce blow-dry time, and leaves hair looking shinier.

Favorite of mine
The CHI Keratin Silk Infusion is a solid hair serum that delivers noticeable improvements in manageability and shine. It has a lightweight, silky texture that absorbs quickly without leaving hair greasy or weighed down. I’ve been using it on my dry, damaged ends after heat styling, and it definitely helps smooth frizz and adds a healthy-looking gloss. The keratin and silk proteins do provide some restorative benefits—my hair feels softer and looks healthier after consistent use. A little goes a long way, so the bottle lasts quite a while, which makes it good value for the price point. That said, it’s not quite as transformative as professional salon treatments or higher-end serums. While it improves the surface appearance and texture, it doesn’t deeply repair significant damage or provide the same long-lasting conditioning that you’d get from premium products like Olaplex or Kerastase. The shine is nice but fades by the end of the day, and severely damaged hair will need more intensive treatment. For everyday use and maintaining relatively healthy hair, this is an excellent affordable choice. Just don’t expect miracles if you’re dealing with seriously compromised or chemically treated hair. Rating: 4/5 stars - Reliable daily serum that punches above its price point, but can’t fully replace professional-grade products.

Great Product!
I have looked high & low for a good, clear, silk-infused treatment for my hair, that doesn't stink. I have used the Bio-Silk formula, but my local stores haven't had it in-stock lately. I also tried the basic, red-lettered CHI Silk Infusion. I liked the product, but not the smell. I have asthma, so I have to be careful with hair products that are strongly or wrongly scented for me. Certain scents induce breathing issues. A couple of years ago, I used Regis Design Line Silk Drops. It was amazing and had a fresh, clean smell. Sadly, they changed the fragrance, and I could no longer use. A nightmare for me is the modern, heavy-bodied, perfumy scents that are all the rage now. The most popular seem to be infused with a musky, heavy, vanilla odor. I can handle most fresh, floral or fruity smells. That musky, vanilla scent is nauseating to me, not to mention takes my breath away! Vanilla is great for baking, but who wants their hair or perfume to smell like that! For those that are wondering, this CHI Keratin Silk Infusion smells a bit different than their red-capped/red-lettered formula. It has a lighter fragrance with a somewhat citrusy tone. It works great, as long as you don't use too much. It softens & helps detangle, adding a bit of moisture & shine. My hair is color-treated, so I thought this would work better, to help strengthen. The smell doesn't bother me either. I count that as a win/win! Was so happy to find it here on Amazon!

Silky, Smooth & Shiny Hair!
The CHI Keratin Silk Infusion is an amazing hair serum. It leaves my hair feeling soft, smooth, and hydrated, with a beautiful shine. A little goes a long way, and it smells incredible too. Perfect for frizz control and restoring damaged hair!

MIRACLE IN A BOTTLE
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

I love this product. Second purchase! I put it in my wet hair after a shower and let my hair dry naturally. It really tames my curly hair and feels nice and soft.

Es importante decir, que es crema, porque el envase da la impresión de que son gotas. Yo lo utilicé en playa conforme a las instrucciones y el resultados es excelente. No alacia obviamente, pero deja el cabello muy suave y mis chinos totalmente controlados, no grasosos, no duros como queda con el mousse, salía con el cabello planchado y hubiera podido quedarme así todo el día, claro, no perfecto pero muy bien controlado. Realmente funciona como tratamiento con resultado inmediato y como un producto para controlar frizz y chinos en ambientes húmedos.

This is a miracle in a bottle! Very nice consistency and smell. It makes my hair look nice when airdried and so silky and smooth when straightened.
