Keratin Hair Serum Oil for Frizzy, Dry, Damaged Hair - Anti-Frizz Shine Gloss Treatment, Heat Protectant with Biotin, Castor Oil and Collagen - 4.25 fl oz

I’ve been genuinely impressed with this Keratin Serum. The formula feels lightweight and absorbs quickly without leaving my hair greasy or heavy, which is a huge plus. After using it consistently, my hair looks noticeably smoother, shinier, and much more manageable. It really helps tame frizz while adding softness and a healthy-looking finish. I also appreciate the ingredient blend — keratin, biotin, castor oil, and collagen — which makes it feel like a nourishing treatment rather than just a styling product. Another big benefit is that it’s alcohol-free, sulfate-free, and paraben-free, making it gentle enough for regular use. If you struggle with dry, dull, or damaged hair, this serum is definitely worth trying

This is 3rd time purchase. Love the scent. Give a nice clean smell to hair. It leaves hair smooth. Does not feel greasy. Everyone comment how my hair smells good, when they give me a hug.

THE ABSOLUTE BEST FOR DRY, CURLY HAIR! ✨️ I am 60 years old and have very dry, wavy, curly hair. I use TreLuxe leave in products, then diffuser to dry. Before my hair is completely dry, I use a few pumps of this, rub my hands together, and scrunch it into my hair, then diffuse a little more. (Don't dry completely.) After about an hour or so, it is usually dry, depending on humidity, and my hair is super soft, no frizz, and shiny! I don't have to wash it again for 3-4 days! Just use a spray bottle with water each day, between shampoos, and it looks amazing! I have used this product for several years! It's a game changer for dry hair!! 💖

I liked this product better than expected. My hair is pretty straight, fine texture but frizzy. A little bit goes a long way but also did not leave my hair feeling greasy. I brushed my hair first (tried both damp hair and dry hair with same result), then added a pump of product to my hands and rubbed together then used my fingers to brush through my hair. I love the way this stuff smells! Hard to tell in pics: 1st pic - no product, 2nd - one side, 3rd - both sides, and back - you can see where I got the product on better one side than the other but it left my hair feeling soft, less frizzy and nice enough I didn’t do anything else to it. No straightening or anything. It also isn’t very heavy where my hair still had a little bit of a wave in it. I gave four stars because it’s a little difficult to distribute evenly but I highly recommend!

Great product!

I bought this on a whim and can’t believe how well it works. It works so well I’m taking the time to write this review and tell you about it. I have quite a bit of hair that is fine and strait but not completely strait like it’s just got a tiny bit of kink in some spots that’s enough to be annoying. My hair is fickle and a total pain. If it gets even a little too dry (common in winter), it looks like a weed. If I use just a tiny bit too much of anything meant to moisturize or hydrate it and make it look not like a weed, it gets weighed down, flat and lifeless. I am constantly looking for something that makes it smooth, strait and shiny and this my friends is it! I’ve spent so much money on expensive salon products and never got results like this. I washed it today, and combed two pumps of this stuff through my hair with my fingers before drying it. I did have to run a flat iron through it to get those annoying weird spots but that’s to be expected of my hair. The point is the end result was exactly what I’ve been seeking for so long! My hair is light, strait, silky and has just the right amount of slip. It actually looks and moves like hair rather than a wad of crabgrass! No more frizzy dried out mess! I am thrilled with this stuff and will be using it regularly from now on.

The best way to put it is I wash my hair everyday because I work in manufacturing, so it gets really humid and hot and I’m around a lot of chemicals, materials that have a type of dust in them, this product I use on the mids and ends, I’ve noticed my hair isn’t as frizzy or looks dehydrated and broken, it’s much softer. The downside of the size of the bottle, I wish it was a little bigger.

I will buy this over and over and over forever! It smells amazing and leaves my hair soft and smooth. I Use it after every wash as a leave in.
