I bought this shampoo and conditioner in July, in hopes that it would give my hair some much needed volume. I personally did not notice much difference in the apperence of fullness or volume, even after one month of use. However, I started to notice my scalp was developing bumps, similar to acne. Come to find out that’s exactly what it was... Scalp acne, caused by the build up of product. The ingredients used to create the thick appearance of the hair strands also began to build up on my scalp resulting in several pimples. I have since changed shampoo and conditioner and the pimples have dramatically decreased in amount! In turn, validating that the causes was indeed this shampoo and conditioner.

I love love love this shampoo. I can't even explain how much it has done for me. I suffer from thin falling off hair. I have tried expensive products and by far the comparison. I have seen a dramatic change in my hair. Now I have fuller and thicker hair. You just have to try it and see for yourself ❤❤❤❤❤

Works just as good the the coconut curls one. I buy the gigantic bottles of this when i can so i can have a matching set of a big conditioner and shampoo for a while. My scalp is never stripped harshly and i love ogx products. It's really the only brand of shampoo and conditioner i trust.

OMG I can’t say enough enough about this product. It’s a drugstore shampoo and I know they sometimes get a bad rep but this specific OGX shampoo is amazing. Your hair is left feeling silky, smooth and hydrated after every use. You can definitely see results within the first wash and it lasts me a long time because a little goes a long way.

I like this shampoo. I used to use it a couple of years ago when I had shorter hair. It was great to define my waves and give my hair volume. I feel it also reduced hair fall but can't be sure since I used other products. Unfortunately, now with longer and color treated hair, it doesn't suit me as well

Absolutely love this brand and the variety of their products. With shampoos and conditioners that aim to treat a number of hair and styling needs. It makes my hair thicker, It leaves it looking/smelling great and much easier to handle. I also love that it contain biotin and collagen which helps with the growth and strength of my hair.

Making a new formula was absolutely unnecessary. This new formula leaves build up in hair, no matter how well you cleanse it. The hair gets greasy and clumpy the next day. The viscosity of the shampoo is the first and most noticeable change, which is now very thick and greasy. Even though shampoo that doesn't make a lot of bubbles is healthier, this one doesn't cleanse the scalp at all. When my hair was wet in the shower, after shampooing, I noticed that it had a weird grease in it – I couldn't wash it off and it stayed stuck into my hair until now. I washed my hair yesterday. This product is mockery and caused me greater hair loss. I do not recommend. OGX, go back to your old formula.

[This review was collected as part of a promotion.] OGX Biotin and Collagen Shampoo is a powerhouse for boosting hair volume and thickness. Enriched with a blend of biotin, collagen, and wheat protein, this shampoo helps to plump each strand, giving hair a fuller and more robust appearance. Its rich, luxurious lather cleanses thoroughly without stripping natural oils, leaving hair feeling strong and healthy. Perfect for those with fine or thinning hair, this shampoo delivers noticeable volume and bounce after just one use. Overall, OGX Biotin and Collagen Shampoo is an excellent choice for anyone looking to achieve thicker, more voluminous hair.

I have used this conditioner multiple times and it really good. I have a pixie cut and I only use a little at a time but what I do use it really helps. My hair tends to get oily pretty fast and this helps with keeping it clean and soft but not dry or greasy.

Absolutely in love with this shampoo and conditioner duo. It smells incredible without being overly scented and it leaves my hair feeling super clean and soft, but also thick and strong. Truly worth the slightly more expensive price than your average drugstore brand.
