VITAMINS hair cosmetics Keratin Hair Serum with Biotin, Castor Oil & Collagen - Anti-Frizz Heat Protectant & Leave-In Shine Treatment for Dry, Damaged, Color-Treated Hair - 4.25 fl oz (125mL)

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!

Bought this for my wife she has only used it for a few weeks. Not only does this product smell amazing she alsoo said her hair feels and looks better than it has in years.

I have very thick hair and it was getting dry as I age. It was also looking frizzy. I have been using this and my hair is so much softer. Although it doesn’t make the phrase go away completely, it definitely tames it. Would buy again.

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!

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.

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 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 use the 3 days a week at least. My girls use this. It helps our hair not look so dead on the ends and helps with frizz control. We all have long normal hair type. The ends just sometimes look dry and this is the perfect fix tomorrow make it look a feel healthy. Also last a while cause a little goes a long way.

This product is amazing, it smooths your hair, smells lovely and gives your hair body. You don't need to use much. I tend to just put it on the lengths of my hair.

Hidrata muy bien el pelo

Prodotto ottimo,disciplina i capelli e li rende meno crespi

Ich bin von diesem Serum begeistert. Ich hatte zuvor von Kérastase Résistance das Sérum allerdings ist es ganz schön teuer und da ist nur eine geringe Menge drin, so dass nach 10-12 Anwendungen die Flasche leer war. Deswegen habe ich nach einem neuen geschaut und das gefunden. Das erste Mal habe ich es im September 2024 bestellt und es hat bis jetzt gereicht. Ich hab einen schrägen Bob bis zur Kinnlänge und da hat immer ein Pumpstoß gereicht um es gut verteilen zu können. Hab es in den Händen verrieben und dann mit den Handflächen über die Haare drüber gestrichen. Es duftet Mega und die Haare sind schön weich und glänzend. Ich hab durch meinen letzten Farbwechsel mir die Haare ordentlich kaputt gemacht aber dank dem Serum brechen die nicht mehr und die kurzen abgebrochen Stellen sind wieder am wachsen. Dafür, dass das Serum von September 2024 bis Anfang März 2025 gehalten hat (bei täglicher Anwendung) würde ich sogar noch einen extra Stern geben . Hinweis: keine Spülung zusätzlich verwenden in der Kombi mit Serum danach werden die Haare irgendwie erschwert. Mit dem Serum lassen sich die Haare auch gut glatt föhnen, so dass man nicht mehr noch zusätzlich mit nem Glätteisen drüber gehen muss. Einziger Punkt der mir aufgefallen ist, dass wenn man am Ende der Flasche angekommen ist, die Pumpfunktion nicht so gut wegen der geringen Menge geht. Allerdings ist der Stab lang genug, so dass man auch damit den Rest rausholen kann. Kann das Produkt nur empfehlen. Die Haare wirken so gepflegt damit !

My hair is very dry. After using this product hair becomes smooth & shiny. Received with well packed.
