I absolutely love this shampoo! It has helped strengthen my hair tremendously over the last couple of months. I feel that my hair stays clean longer and has less breakage.

It's a must have in my household!! I decided to change my shampoo and give this one a try and it did not disappoint … it helps my hair with volume , the smell is amazing and it keeps it very shiny.

I use this shampoo and conditioner every time I shower. I have very fine and thinning hair. It creates volume before I use any additional product which is nice because it let's me not layer so much in my hair.

Adds noticeable volume and fullness with a great scent, without weighing hair down or leaving residue. Smells great! Super affordable. My hair felt noticeably different after one use.

I bought this recently, Oct 2025 only to find a new formula. Why??? It's thinner, doesn't lather as well, not rich and creamy and leaves hair flatter. The old formula you feel the body coming into your hair. After blowdrying using the new formula hair is less volumised. The hunt for a new shampoo begings I guess. Why do brands do this to stuff that worked. Won't buy it any longer after yrs of using it.

I've been using OGX Thick & Full + Biotin & Collagen Shampoo for a few weeks now, and I actually like it. It smells really nice, kind of sweet and fresh, and it lathers up well without needing a ton. My hair feels a bit fuller after using it, though I wouldn't say it's a dramatic difference. It doesn't weigh my hair down or leave any residue, which is a plus. Overall, it's a solid shampoo if you're looking for something affordable that gives a little volume boost.

This is a really good shampoo to thicken hair. It has a most unique scent. It smells powdery yet musky. I didn't like it at first but the scent grew on me as I continued to use the shampoo. It is a strong scent that stays in your hair all day long. My hair feels soft and manageable and definitely more volumized after use.

OGX Beauty Biotin & Collagen Shampoo is designed to add volume and thickness to fine or thinning hair. Infused with biotin, collagen, and wheat protein, it strengthens strands, promotes fuller-looking hair, and leaves it feeling healthy and nourished.

OGX makes such good products. I personally love this kind for my hair type. I have medium thickness, long, straight hair. This is perfect for me. It leaves my hair feeling clean even when I only wash once a week. I think they are a great price, especially because you can almost always find coupons for this. The only annoyance I have is the bottles/lids are curved so you cannot leave them upside down to help with getting the product out.

I really like this shampoo from OGX. The scent is so nice and fresh, it stays in my hair for a while after washing. The texture is creamy and feels gentle on the scalp. After using it a few times, my hair feels fuller, smoother, and easier to style. It gives a little bit of volume without drying my ends. The packaging is cute and easy to hold in the shower. For the price, it works really well — honestly, better than some more expensive brands I've tried. Definitely one of my favorite drugstore shampoos for keeping hair healthy and soft
