OGX Thick & Full + Biotin & Collagen Volumizing Shampoo, Nutrient-Infused Hair Shampoo with Vitamin B7 Biotin Gives Hair Volume & Body for 72+ Hours, Sulfate-Free Surfactants, 13 fl. oz

I've tried a lot of volumizing shampoos over the years, and honestly, many of them seem to follow the same formula: give you volume for a day, then leave your hair feeling dry, tangled, or like it has some weird coating on it. My hair is fairly fine, so I'm always chasing a little extra body without turning my shower into a science experiment. This one surprised me in a good way. The first thing I noticed was how clean my hair felt after washing. Not squeaky, stripped clean, just clean. My roots didn't feel greasy the next morning, and my hair had noticeably more lift than usual without feeling stiff or overloaded with product. I was also happy with how easy it was to work through my hair. Some volumizing shampoos leave me fighting tangles before I even reach for conditioner, but that wasn't the case here. My hair felt smooth while rinsing and was much easier to comb through afterward. It also left my hair feeling soft and moisturized, which isn't something I normally expect from a volume-focused shampoo. The scent is another win. It has a fresh, slightly sweet fragrance that feels salon-like without being overpowering. I could still catch little hints of it throughout the day, which I always appreciate. As someone who enjoys trying different haircare products, I also like that it uses biotin and collagen while remaining free of sulfated surfactants. Whether those ingredients are the secret sauce or not, my hair looked fuller, felt healthier, and behaved better after using it. The bottle isn't huge, but at around $7, I think the value is excellent. If you're looking for a shampoo that adds volume while still leaving your hair soft, manageable, moisturized, and free of excess greasiness, this one is definitely worth trying. Easy 5 stars from me.

This shampoo is fantastic! I have fine hair but LOTS of it! I always use a volumizing shampoo but my regular brand is almost $35 for an 8 ounce bottle and it’s not as nearly effective as this one. I couldn’t believe how thick my hair felt when washing with it but was unbelievably full when air dried! It’s clear and has a nice light scent and lathers really well. My hair feels so fresh and clean after using this shampoo. Highly recommend!

OGX Thick & Full + Biotin & Collagen Volumizing Shampoo has become my go-to shampoo, and I keep coming back to it because it consistently delivers great results. It leaves my hair feeling clean, soft, and noticeably fuller without weighing it down. I love how it adds volume and makes my hair look thicker and more manageable. It also has a pleasant scent that isn’t overpowering, and it lathers nicely so a little goes a long way. After trying many different shampoos over the years, this is the one I rely on the most. If you’re looking for a shampoo that helps boost volume and leaves your hair looking fuller, this is definitely worth trying, it’s been my go-to for a reason.

Decent lather. Nice smell. Cleans well.

I’ve been using this shampoo for a while now, and it’s one of the few volumizing shampoos that doesn’t leave my hair feeling heavy. My hair feels clean, soft, and has a little more lift at the roots after it dries. The larger bottle is a great value since a small amount goes a long way. It lathers well and rinses out easily without leaving any residue behind. The only thing I noticed is that it can be a little drying if I use it every day, so I usually pair it with a moisturizing conditioner. Other than that, it’s been a solid shampoo for adding volume and making my hair look a bit fuller.

I was skeptical of the product and reviews. I have fine/thin hair that is combination oily/dry depending on the shampoos. I am a wash n go woman, but this shampoo helps keep the shine and softness. My hair appears to have more body and volume. I have just started using it the last 2 weeks and alternate with other shampoos I have, but this one is truly great. The smell from the bottle smells like an "old lady" (no offense to anyone) but after washing it out there is no lingering smell from what i can tell. Nice, clean hair and without flattening effect.

This shampoo has a pleasant scent and did give my fine hair some added volume. Unfortunately, I also noticed more breakage while using it and believe the formula may have contributed. It may work well for other hair types, but it wasn’t the best fit for my fine hair.

This product created the illusion that I have more hair than is there. This is most agreeable with me. It was simple as an ordinary hair wash, nothing difficult or fancy. After drying, the flat iron was used and gave me a normal looking head of hair. Wow ! What a cool surprise. It smells nice but not overwhelming. My hair looks like it always does so all is good. I recommend it.

Amo este producto! El aroma está increíble deja el cabello súper sedoso y con brillo. Y en lo personal cumple perfecto con su función. Detuvo mi caída de cabello (secuela covid) después de un mes de uso. Estoy en el segundo frasco y ya me está naciendo nuevo cabello. Y ah acelerado notablemente el crecimiento de mi cabello

This shampoo has completely exceeded my expectations. I am self-conscious of my thin hair, and was looking for a product to add some volume to my flat, fine strands. This shampoo does exactly that. I notice that it certainly looks thicker after washing and conditioning with this product line. I colour my hair blond, and this shampoo hasn't had any effect on the colour. I don't suffer too much damage, for example split ends, but my hair does feel soft and moisturized after using this line. I doesn't manage frizz that well, so if I like my hair air-dry I do get quite a lot of flyaways, but this isn't my primary hair concern. I love this shampoo for the thickening effect I've seen. It also smells great, and the shampoo is much thicker than other shampoos I am used to using, which I think has led me to use less product than I normally would. Lathers super well and rinses out without leaving any feeling of icky residue. Highly recommend for those looking for a thickening shampoo!

Highly recommended It makes my hair thick and smells good on my hair

This has honestly been one of the best shampoos my daughter and I have used. Smells delicious, my hair doesn’t end up oily one little bit and just gives a really good clean !!

No Doubt on it awesome product
