I had a hard time finding a good shampoo and conditioner that didn't make my hair fall out (I have hair issues) and this makes my hair feel amazing! It makes it look thicker and feels so soft! This is the only brand of shampoo and conditioner I will use!

So I have MS, and I was on this wicked medicine for quite some time that made me lose a LOT of my hair - roughly about 40% I'd say, and I had extremely thick hair. Well, today is only the second day I have used this shampoo - let me start by saying that the results are quite instant. I mean, as soon as I applied this to my hair yesterday, within seconds it was almost as if my hair expanded. I felt a fullness to my hair very suddenly. It dried beautifully leaving my hair looking extremely voluminous and feeling softer than it has ever been, even when it was healthy. Seriously. This is the best shampoo/conditioner I have come across yet, and it required absolutely no time at all to achieve the results I was looking for. I recommend this to anyone, without hesitation. It also does have a nice smell, comparable to a musk - it's soft and relaxing :) AND they're cruelty free!

I have been using this shampoo for several years and it has been great for thickening my thinning hair. However, I have just had to buy a replacement bottle and used it this morning for the first time. The first thing I noticed was that the shampoo is now clear instead of a shade of purple, then that while it softens my hair it no longer seems to have the thickening effect. I was confused but when checking the bottle (which looks exactly the same as previous bottles) there is a very small addition which says ‘new improved formula’ and the word ‘thickening’ is no longer there. I don’t know why companies feel the need to tamper with winning formulae, but I am very disappointed that my favourite shampoo is no longer.

[This review was collected as part of a promotion.] I really wanted to like this shampoo but unfortunately my fine and color-treated hair did not respond well to it. I have dark brown hair and this brought out a ton of red in my hair. It also made it super oily after not even a day (I can usually go 2-3 days without washing with other shampoos). It does smell great and made my hair super soft! If you have medium to thick hair that isn’t color treated I would definitely recommend trying this!

[This review was collected as part of a promotion.] I’ve been on the hunt for a shampoo that will help with my fried hair that I messed up bleaching and something to help thicken up my hair again! This stuff has made my hair so soft and smell good! I haven’t noticed any difference on thickness but I’ve only used it for a week! This brand has always been one of my go too and I definitely recommend!!

[This review was collected as part of a promotion.] Ogx biotin & collagen shampoo is good for normal hair. I have an oily scalp and fine hair so it’s not the best for my scalp but my mom has normal scalp, tons of thick hair and she loves this shampoo and conditioner combo. It smells really good and I think it’s fairly priced. As you can see on the picture, my hair looks a little clumpy at the roots.

[This review was collected as part of a promotion.] The Biotin & Collagen Shampoo is exactly what my color-treated dry hair needed. The scent is light and not overpowering compared to other drug store brands. My hair feels soft and nourished after use along with the Biotin & Collagen Conditioner. I was shocked how my hair wasn't tangled after washing it and I attribute it to the new shampoo / conditioner combo. I am a big fan and recommend.

[This review was collected as part of a promotion.] Love this biotin and collagen shampoo by ogx. It makes my hair feel nice and clean without over drying it or stripping too much moisture. It also suds up nicely and you don’t have to use too much for it to be effective.

[This review was collected as part of a promotion.] I was given this product complimentary for my honest review. Honestly I can’t really tell much of a difference from the amount of time I’ve been using it. Maybe a little more volume. It smells absolutely amazing though. It has a nice consistency and suds up well. I’m going to continue to use it to see if I get more results.

[This review was collected as part of a promotion.] If you are looking for an inexpensive shampoo, this is exactly what you need. Good ingredients, pleasant smell feels good on the hair leaving it clean and fresh it works well the packaging is all right and I recommend for you guys to try it out it’s a go too product.
