This is a good Shampoo. I have used it on and off for a couple of years. I have fine and thin hair. This isn't too heavy. It smells great. It makes my hair smell great. I change Shampoo often and this ine always stays in the line up. I absolutely recommend it.

I bought this because of the good reviews and it was pretty cheap! I needed a volumizing shampoo because my hair is really thin and flat. It worked.. fine? I got out of the shower and my hair did seem more “volumized” but it was just fluffy and sorta dry. I had to use a hair serum after

I bought this shampoo a couple of months ago, and I've never been happier. I got ill a few years ago and since then had trouble with my hair - it fell out, was extremely dry and thin and constantly broke plus I've had lots of people asking me whether I was going through chemotherapy as it looked that bad and unhealthy. I also have a sensitive and dry scalp that I struggle with. I tried so many shampoos since I fell ill, for example l'oreal total repair and other expensive brands that said it would repair my hair. None of them worked for me, in fact it got even worse! My hair fell out even more because of them and got even more dry than it already was, disaster! One of my friends then recommended this brand as she swears by the keratin line, but I thought I'd give this line a try as I crave that volume. The first week or two I think my hair needed to get used to it, my scalp got itchy and a bit flaky/oily which is why I gave it four stars and not five. However, after that first week or two that all was gone and I started seeing results! After using it for a few months now my hair is completely changed and feels like a life saver for my hair. My hair is now incredibly healthy, it's very shiny and looks extremely full and lots of volume like the shampoo claims. I think it even helps to grow more hair! It doesn't even fall out any longer, only a couple of hairs a day that's it. I'm beyond grateful to have found this shampoo and I definitely recommend it, my hair has never looked as amazing as it does now - game changer!

So summer of 2015 i was looking to grow my hair it was all dry and slowly began to thin i went on youtube and searched how to grow your hair longer and majority of the "Hair Guru's" kept on mentioning biotin and good hair routines now i had never heard of this biotin but i was desperate to sure give it a try one day i was in my local beauty store looking for shampoo+conditioner when i saw this product and to be honesty i only picked it up because of the biotin label on it i purchased this item as well as its conditioner and i must say the is the best product i've ever spent my money on i fell in love with the scent and loved the after feel of my hair after i used it i can definitely see growth in my hair and my roots seem intact and stronger organix has now became my go to when it comes to my hair definitely looking forward in trying their other products xo

I use this in conjunction with the conditioner and it does really make a difference! I was interested because have thicker, fuller looking hair is usually the kind of shampoo and conditioner combo that I go for. For the price of these two together it works great and smells good too!

I have used OGX Biotin &Collagen for many, many years and loved it. It made my thin straight hair look great, and most importantly did not strip the color out of my highlighted hair. I recommended it to many people over the years, and was always happy with the product. However, I was so surprised when I recently bought a new 25 oz. bottle and used it for the first time. I actually thought I’d bought the wrong product! Instead of a creamy violet shampoo it was a thin, sticky yellow that made me fear I’d ruined my hair, since the shower feel was very unpleasant. Also, instead of the lovely floral scent, it smelled like old wax. After styling, my hair was somehow dried out and greasy at the same time. The only good thing I can say about it is that it didn’t affect the color in my hair, and my hair was shiny (but greasy). Fortunately the conditioner doesn’t seem to be changed much, except for the coloring (violet to white), and it still has the old smell. I’m very sorry to say that I won’t be using this shampoo any more. I had to throw out an almost full bottle, and will have to look for another alternative. Very disappointing, OGX.

[This review was collected as part of a promotion.] If you're on the hunt for a shampoo that promises to add volume and strength to your hair, OGX Biotin & Collagen Shampoo might be just what you need. This shampoo is formulated with biotin, collagen, and hydrolyzed wheat protein to help give your hair a fuller, healthier look. The shampoo has a lovely, subtle fragrance that's not too overpowering. It lathers up nicely, giving you that satisfying clean feeling without stripping your hair of its natural oils. One of the key ingredients, biotin, is known for its role in promoting hair health and growth. Collagen helps to add volume and thickness, making your hair look more luscious and full. The hydrolyzed wheat protein strengthens your hair, reducing breakage and split ends.

I don’t know why this shampoo has such high ratings everywhere but I hated it. It made my hair so dry and frizzy which was never a problem before. The ingredients aren’t considered “clean” which I wish I looked into more before purchasing such a big tub of it but I’ve thrown it away after using it for a month.

I absolutely love this shampoo! The smell is so great! I use this one because I have thick and oily hair that is really annoying. This shampoo is one that I have been using for quite a long time and I am very satisfied with it. You will notice your hair becoming less oily and stronger!

I have super fine and straight hair and am always looking for new products that will make it stronger and thicker. I started using the bIotin and collagen shampoo, bc I know both of those additives are great for thicker, fuller looking hair. I do feel a difference in my hair and I also feel like I do not have to wash it as much (used to wash it every day..... now I can go every other). I will buy again!
