You might assume that expensive salon brands are the only way to achieve volume, but drugstore formulas often prove that effective ingredients matter more than a high price tag. After evaluating these six options and analyzing buyer feedback, I have ranked them by their performance and value. My goal is to guide you toward the best volume results for your specific needs. Here is the honest breakdown of the OGX lineup I tested.
1. OGX Thick & Full + Biotin & Collagen Volumizing Shampoo, 25.4 fl. oz
This version earns its rank because it offers the best balance of price and longevity for the average user. It provides a reliable amount of lift without overwhelming fine hair.
I think this is the smartest entry point for anyone who already knows they enjoy the standard formula. The size is generous, though the sheer volume of the bottle can be slightly awkward to handle in a cramped shower.
Buyers frequently mention that this size lasts for months.
Many users appreciate the consistent, light scent.
The formula is often cited for its effectiveness on fine hair types.

2. OGX Thick & Full + Biotin & Collagen Shampoo & Conditioner, 2 x 13 fl. oz
This set is for the buyer who prefers a complete routine to ensure their hair receives consistent treatment from start to finish. Using both products together creates a more cohesive effect than using the shampoo in isolation.
In my view, keeping the brand chemistry consistent is helpful for those seeking maximum body. You might find the individual bottles a bit small if you have very long or thick hair.
Users often report that the conditioner helps with detangling.
Feedback suggests the pair works well for daily washing.
The set is a common choice for those looking for a quick, matching routine.

3. 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
The most interesting feature here is the 72-hour claim, which suggests a longer window of hair body than most standard shampoos. It serves as a perfect low-risk trial for those new to the brand.
I find this smaller bottle ideal for travel or for anyone who wants to see if the sulfate-free surfactants work for their specific scalp type. Be aware that smaller bottles often have a higher price per ounce compared to the larger containers.
Users value the convenience of the smaller bottle size.
Many report feeling a noticeable difference in hair texture after the first wash.
The shorter bottle is frequently noted as being easy to store.

4. 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, 25.4 fl.oz (Pack of 2)
The most common complaint regarding this set is the weight and storage space required for two large bottles, yet the value proposition is hard to ignore. It is a practical solution for households where multiple people share the same product.
I believe the trade-off is worth it if you know this is your daily staple. Just ensure you have the shelf space to accommodate the bulk sizing before committing to this much product.
Buyers often highlight the money saved by purchasing in packs.
The large size is frequently praised for minimizing shopping trips.
Some users note that the pump mechanism is a major convenience.

5. OGX Biotin & Collagen Extra Strength Volumizing Shampoo for Thicker, Fuller Hair, 25.4 fl oz
Compared to the standard volumizing shampoo, this version feels like a concentrated upgrade for hair that needs a bit more help staying upright. It delivers a noticeably thicker feel that makes it my top pick for those prioritizing density.
I prefer this formula because it does not feel as heavy as other "thickening" products I have researched. You should keep in mind that the extra strength label implies a richer formula, which may not be necessary if you have very fine, oily hair.
Reviews consistently point to a visible increase in hair volume.
Many users prefer this over the standard version for lasting body.
The rich texture is often cited as a standout feature.

6. OGX Biotin & Collagen Extra Strength Volumizing Shampoo for Thicker,Fuller Hair,25.4 fl oz,(Pack of 2)
This product became popular due to its reputation for high-density results in a convenient bundle, and my research suggests that the consensus largely holds up. It appeals to those who want the best formula but do not want to worry about running out for a long time.
I think this is the most efficient way to buy for anyone who has already settled on the extra strength version as their permanent choice. It feels like a sound investment for your grooming routine, provided you are confident that the formula suits your hair type.
Long-term users praise the consistency of the results over time.
The bundle is often favored by families or households with multiple users.
Buyers frequently mention that this pack offers the best long-term value.

Choosing Between Them
For those seeking the best performance, I recommend the Extra Strength formula as your primary choice. It is the most effective option for achieving a thicker, fuller look, making it the ideal selection for buyers who want maximum hair density. If you prefer a lighter touch, the standard volumizing shampoo remains a reliable choice for everyday needs, while the convenient 2-pack bundles are perfect for those who want to stock up.
As you navigate these options, remember that sulfate-free cleansers often produce less lather than traditional shampoos. This does not mean they are failing to clean your hair; it is simply a different experience that you should expect during your wash. Choosing the right version depends on whether you value the high-density results of the extra strength formula or the lighter, more economical feel of the standard line.
