Love this shampoo. It keeps my normally flat hair looking thick and vibrant. The smell is great, and the shampoo itself lathers really well; plus you don’t need as much as normal shampoo to get the same job done. Only giving 4 stars because the bottle SUCKS. You never can get all the shampoo out, and once you get past the half way point the bottle punches and your left taking the cap off and trying to dig the rest of the shampoo out

I don't understand why there are so many good reviews. This shampoo has failed to help my hair in the ways its says. Its also does not rinse out well and continues to leave my hair feeling grimy and unwashed. It also leaves my hair super dry and the static is ridiculous. My hair was better on the shampoos with sulfates than without. If your shampoo worked i wouldn't have to use dry shampoo on top of it to make it look like i actually washed my hair after its dried. Would not recommend for thin hair at all..

[This review was collected as part of a promotion.] Ive been through an entire bottle of this stuff. And it works! Just touching your hair youll notice it feels thicker. Ive tried so many products that either weighed my thin hair down or broke it off. This one is different and it smells great too. Also to add more volume when using this blow dry hair with your head upside down. For a girl with thin fragile hair this has helped my hair grow and look fuller. The first shampoo I've ever fell in love with!

My hair is so bouncy and full of body after using this conditioner it lathers up great so each strand gets some love I have noticed my hair is stronger and less likely to experience breakage I love all ogx products and will be repurchasing this[product:ogx-biotin-collagen-shampoo]

OGX Thick & Full Biotin & Collagen Shampoo & Conditioner are miracle workers! My hair is exceptionally thin and lifeless. I have tried so many products claiming to increase hair thickness that I have lost count, and none of them have worked. This product delivers! OGX contains vitamin B7 biotin to maintain growth and strengthen hair, collagen for healthy hair, and hydrolyzed wheat protein to pump up the volume. The scent is a wonderfully light vanilla and jasmine that really pleases the senses. I love that this product is paraben-free and sulfate-free! It keeps the good oils in, without disrupting the endocrine system. I was in a rush and decided to just do a quick shampoo without conditioner and I was pleasantly surprised at how soft, shiny, and detangled my hair was without conditioner. This product is a complete win!

I bought this a couple months ago and it smells amazing I bought the shampoo and conditioner set together the only downside is if I don’t wanna use conditioner my hair becomes extremely dry is very stripping to my hair and I have naturally extremely oily hair

I like this shampoo. The fragrance is light and not overwhelming . I feel like it lives up to its promise if giving my hair a plump boost. I bought the double size bottle and feel like the product has lasted well, probably because the formula is really thick. The price was within reason.

I have always been someone that is very picky with what they will put on their hair. I have very long and thick hair and was struggling to find something new to use. I had a friend recommend this shampoo and conditioner and it has been life changing! It had helped with my dry split ends without causing my scalp to get oily quickly and the smell is hands down the best sent for shampoo I have ever had

If there were more than 5 stars this shampoo would easily get it. I have always had very oily hair and no matter what shampoo and conditioner I used my hair would get oily by the end of the day and I would HAVE to wash it or it would get even worse the longer I waited. I purchased this shampoo with the conditioner on a whim because I have straight and thin hair so any kind of volume to give it some life sounds great to me and I’ve used other volumizing products and they have done nothing for my hair. After just the first time using it I could feel my hair already thicker and on top of that it did not get oily whatsoever even after more than 24 hours which never happens for my hair. I immediately went out and bought the bigger size so I won’t run out 10/10 recommend!

I recently purchased this after figuring out if this was still causing people’s hair to fall out. I have thin hair that comes out due to medication and I wanted to see if this would help being the fact that it has biotin in it. I like it so far haven’t noticed too much of a change but it does get your hair clean and it smells nice.
