Who is it for?
Biotin is a staple in topical hair products including OGX Biotin and Collagen Shampoo due to its strong connection to promoting stronger, fuller, and thicker hair with every wash, which is excellent for flat to medium-volume hair.
But, it’s not suitable for those with gluten sensitivity since the products contain wheat protein.
Further, OGX Biotin & Collagen Shampoo has silicone, which is not safe for curly and coily hair as it may cause build-up, weigh the hair down, and jeopardize the curls over time.
In general, OGX is not a bad shampoo, but it’s not ideal for curly-haired people. Get yourself a detox shampoo once a week to get rid of the build-up if you really want to try the product and see if it works for you.
As far as hair textures are concerned, OGX Shampoo is suitable for medium and thick hair. We found mixed reviews that OGX added weight to very fine hair. Those who have oily hair/ scalps also noticed hair easily becomes greasy. If your hair is dry and not fine, this shampoo can be your go-to. You can also consider the OGX Argan Oil Shampoo for dry and dull hair for extra shine.
The good news is OGX has plenty of moisturizing agents, which makes it great for dry, brittle, and high-porosity hair. Plus, it’s sulfate-, alcohol-, and paraben-free, another reason you’ll love this shampoo. If you have extremely damaged hair that needs hydration, consider the OGX Coconut Milk Shampoo.
Next, let’s check out the formula.
The Feel, Scent, and Packaging
Heavy shampoos tend to leave residues behind, which makes for oily and very fine hair clumpy. The OGX Biotin and Collagen Shampoo has a translucent, weightless feel with a slightly violet hue. Many found it didn’t lather up very well, but it was easy to rinse out and left your hair looking bouncy and full.
OGX is infused with bergamot, jasmine, and vanilla scent, which leaves a pleasantly sweet fragrance in your hair. It doesn’t last long though, which is nice if you’re not the biggest fan of fragrance in shampoo.
The shampoo comes in a bulky squeezable violet bottle with a golden flip-flop cap. Due to its slightly dome-shaped cap, it’s quite hard to tip it upside down to deposit the shampoo until the last drop.
Next, let’s check out the value.
Where to Buy OGX Thick & Full Biotin & Collagen Shampoo?
When it comes to pricing, OGX won’t let you down. This moisturizing shampoo is currently only $6.99 for 13 fl oz at Amazon, which is super affordable. Other biotin-infused shampoos we’ve reviewed cost between $17 and $30, which are different in formulas and sizes. But, if you prefer something inexpensive with a lot of product, then OGX is good.

Besides delivering more volume, OGX also nourishes and repairs damaged hair.
Additionally, we’ve also found a couple of reviews that mentioned OGX shampoo helps reduce signs of hair loss and encourages hair growth.
Overall, OGX Biotin and Collagen Shampoo did a great job to promote thicker-looking hair and nourish lifeless hair, making it healthier than before.
Next, let’s check the bad reviews.
The Complaints
Compared to positive reviews, there are only a small number of critical reviews. However, we often found reports that the shampoo doesn’t lather well, so you’ll need to use a large amount to get a better lather.
Some users noticed heavy and greasy hair after using the shampoo, especially if not rinsed thoroughly.
OGX Biotin and Collagen Shampoo is formulated to hydrate your hair, which means it may not be suitable for oily hair/ scalp. Thus, we suggest taking OGX Extra Strength Refreshing Scalp + Teatree Mint Shampoo to deeply cleanse while also promoting fuller hair.

OGX Biotin and Collagen Shampoo Cons & Side Effects
After learning the benefits of OGX shampoo, we discuss any side effects that may occur while using the product. As you can see in the Ingredient Breakdown section, OGX Biotin and Collagen contains several fillers (dyes, silicones, and preservatives) that may be harmful to your hair, scalp, or skin.
Here are the possible side effects of OGX Biotin and Collagen Shampoo:
- Although it’s sulfate-free, the shampoo contains another strong surfactant (Sodium C14-16 Olefin Sulfonate), which may strip your hair moisture too much. If you have extremely dry and curly hair, make sure to use the conditioner afterward.
- Cocamidopropyl Betaine (surfactant) in OGX Shampoo may pose allergic reactions to people who are sensitive to it. It also may cause eye irritation, if the shampoo runs into your eyes as you shower.
- OGX Biotin and Collagen Shampoo is not gluten- and wheat-free. Avoid using the product if you are allergic to wheat.
- The shampoo is not free of silicone. It may leave residues or build-ups on your hair over time, leaving your hair looking limp and greasy. Since Amodimethicone is not water-soluble, wash your hair with a detox shampoo once a week to get rid of the build-ups.
- Synthetic colors are present in OGX Biotin and Collagen Shampoo. They’re usually produced from coal tar or petroleum. Unfortunately, these may do more harm than good for you, such as allergic reactions. If you’re looking for dye-free shampoo, check out Viviscal Shampoo or HAIRtamin Biotin Shampoo.
- The shampoo contains sodium benzoate that helps prevent the growth of mold, fungi, and bacteria in the formula. However, one study showed that it may cause itching and swelling in some people with a preservative sensitivity.
