VITAMINS hair cosmetics Keratin Serum with Biotin, Castor Oil & Collagen

BEST HAIR PRODUCT OF MY LIFE!!!! I’ve purchased hundreds, if not thousands of hair products over multiple decades of my life. Suffice it to say I have a veritable arsenal of hair products. There are many products in my arsenal that offer very good results for what I’m looking for in a hair product, but this product goes way above and beyond, offering OUTSTSTANDING results. It didn’t just soften my hair, as many products do, my hair feels brand new, like it did seven decades ago when I was a completely natural blonde. Beyond the softness and sheen it gave my hair, it also tripled the volume of my hair just because it made all the damaged hair healthy again. I’ll be a lifetime consumer of this product. PLEASE don’t discontinue it!

Pleasantly surprised. Makes my hair quit smooth and shiny. I like the scent.

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

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!

This product smells great!! I can already see a difference in shine and softness. When I apply it I feel like my hair instantly feels stronger and more elastic.

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 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.

I love this product. I am 68 y.o. and only wash my hair once a week as it is dry. My hair is thick and coarse but I still color it so I need some help with moisture. This item FITS the bill. I apply about a dime sized amount in my hands and rub it through my strands concentrating on the middle and ends while my hair is a little damp. It has helped tremendously and leaves my hair looking and feeling moisturized. I've ordered this a few times and will continue.

Lo usa mia moglie e l'ha riacquistato perchè lo considera efficace , mantiene i ricci morbidi ed evita il crespo anche con il venti e l'umidità.

Hidrata muy bien el pelo

I am a return customer for this product, its very good on my thick unruly hair, does exactly as it says on product description 😊

Zeer goed product! Haar ziet er veel beter uit

DIe Haarpflege ist leicht zu benutzen und erweckt meine Sinne durch einen angenehmen Duft und leichte Textur. Da meine Haare über einen Meter lang sind, ist das Produkt mein treuer Begleiter geworden und verleiht dem Haar Stärke, Geschmeidigkeit und gesunden Glanz. Leichte Handhabung sei auch nicht zu vergessen.
