Choosing the right hair growth remedy when there are so many on the market these days isn’t easy.
But, I’ve got ya!
I have taken a deep dive into two beasts in the hair growth game and gone head to head with them: OGX Thick & Full vs. The Ordinary Multi-Peptide Serum.

We’re looking at things like:
  • Efficacy
  • Application method (whether you want a topical or pill specifically, this is good to know)
  • Hair suitability (some topical products don’t work as well for different hair types)
  • How long to results?
  • Price (which, of course, overall will be determined by how it takes to get results
  • And all the rest…

OGX Thick & Full Biotin & Collagen Shampoo

Application Method: Topical (Shampoo)
Active Ingredients: Biotin, Collagen
Hair Type Suitability: All Hair Types
Usage Frequency: Daily

What The Sales Page Doesn’t Tell You About OGX Thick & Full

Initial Impressions and Scent

First Reaction: When I first picked up the OGX Thick & Full Biotin & Collagen Shampoo, I was captivated by the vibrant purple bottle. It’s eye-catching and feels nice in the hand—not too bulky or slippery in the shower.

Scent Experience: Upon opening the cap, I was greeted with a sweet and somewhat floral aroma that felt quite luxurious for a drugstore brand. The scent is strong coming out of the bottle but becomes subtle once you’ve finished your shower, leaving just a faint hint in your hair.

Fragrance Sensitivity Caution: For those sensitive to fragrances, it might be a bit much; I wish there was an unscented version for customers who prefer or need that option.

Lather and Cleanse Quality

Lather Satisfaction: The shampoo lathers well—just a small amount goes a long way. It creates that satisfying sudsy experience without needing to use half the bottle, which is great for long-term value.

Cleansing Ability: As for its cleansing properties, my hair certainly felt clean after rinsing—the “squeaky clean” kind of feel. However, depending on your hair type, this can be a double-edged sword; it’s effective at removing buildup but can also strip away natural oils if used too frequently.

I wish there were more clarifying details on how often it should be used—daily users with dry hair might find it exacerbating their condition over time.

Results on Hair Texture and Volume

Texture Transformation Promise: The product claims to help achieve thicker and fuller hair thanks to biotin and collagen—you’ll see this plastered all over their marketing. Did my hair transform into a lion’s mane? Not exactly. There was some noticeable volume after drying, but don’t expect miracles from just one wash or without additional styling products.

I did appreciate that my fine hair didn’t feel weighed down; instead, it had an airy lightness post-blowout which suggested some added volume. For those with already thick hair seeking even more volume though? You might not notice as much of a difference as someone with finer strands like me does.

Packaging Functionality and Ingredients Insight

The bottle design is functional—I’ve never had any issues with leakage or the product dispensing too quickly (a common annoyance). Still, as someone who tries to make environmentally conscious choices when possible,


In terms of ingredients used—I’m not an expert—but after doing some research online due to personal interest in product formulations,

}I found out this shampoo contains sulfates which are known to provide cleaning power but can also be harsh on sensitive scalps,. This made me question if long-term use could potentially damage my scalp health,.

The Ordinary Multi-Peptide Serum for Hair Density

Application Method: Topical (Serum)
Active Ingredients: Peptides, Caffeine
Hair Type Suitability: All Hair Types
Usage Frequency: Daily

What The Sales Page Doesn’t Tell You About The Ordinary Multi-Peptide Serum

First Impressions and Packaging

When I first got my hands on The Ordinary Multi-Peptide Serum for Hair Density, the minimalist packaging immediately stood out. It’s quite on-brand for The Ordinary—a no-frills, clinical vibe that suggests you’re getting something backed by science without any unnecessary fluff. The dropper applicator was a thoughtful touch, making it easy to dispense the product without wasting any.

I liked that the bottle was tinted; it gave me the impression that the active ingredients would be protected from light degradation. Overall, my initial thoughts revolved around how straightforward everything seemed—the product claimed to support hair health, making it appear fuller and denser. Who wouldn’t want that?

Texture and Application

The serum itself has a slightly viscous texture—not too runny but not thick like an oil, which meant it didn’t drip all over the place when applying. I found it easy to work into my scalp without feeling greasy or weighing my hair down.

Application-wise, I’d section my hair and apply a few drops directly onto the scalp, then massage it in with fingertips until I felt like it was distributed evenly. This became part of my nightly routine; however, I wish there had been more guidance on whether or not this could replace other hair products or if I should use them alongside this serum.

Results: Expectations vs Reality

Now let’s get real: Most people considering The Ordinary’s hair serum are probably looking for miracles—thicker locks or some sort of visible transformation—and who can blame us? But here’s what actually happened:

I used the serum consistently for several months because I know that with products like this one—patience is key. Did I notice a Rapunzel-like change? No—but then again, that wasn’t what I expected deep down (despite secretly hoping). My hair did feel stronger and seemed to shed less during brushing or washing. However, there wasn’t a significant change in density—at least not one that others began commenting on.

In terms of new growth, if there was any increase in speed at which my hair grew or new hairs sprouting up where previously there were none—it wasn’t dramatic enough for me to attribute solely to this product.

Scent and Sensitivity

One thing you might not pick up from just looking at the bottle online is its scent—or lack thereof—which is actually pretty good news if you ask me! There’s no overwhelming fragrance with this serum—a big plus since fragrances can be irritating for some people.

As someone with somewhat sensitive skin myself, another crucial factor was how gentle The Ordinary’s serum would be when applied directly onto my scalp every night. Fortunately for me—and potentially many others—I experienced no irritation or adverse effects from using this product regularly.

Value for Money?

Although results were more subtle than outstandingly obvious, when you consider the price point of The Ordinary’s serum, especially compared with other high-end hair treatments promising similar outcomes—it does seem like reasonable value.

You’re getting quite a bit of product that lasts several months even with daily use; so dollar per application-wise—it makes sense as an investment into your overall hair care routine. However, manage your expectations accordingly—this product supports your existing hair rather than reviving dead follicles back into action overnight (or even over many nights).

Would I buy it again? Possibly—if only to maintain general scalp health rather than as a solution for significant thinning issues. But hey—it’s all about finding out what works best for you through trial and error…and right now; this particular serum feels like another step in figuring out what makes my mane happiest!

Final Comparison

Initial Impressions and Scent

Winner: OGX Thick & Full Biotin & Collagen Shampoo. With its eye-catching purple bottle and luxurious floral aroma, OGX makes a strong first impression. While the scent might be strong for some, it’s a clear favorite for a sensory experience. The Ordinary, while minimalistic, doesn’t provide the same olfactory satisfaction.

Lather and Cleanse Quality

Winner: OGX Thick & Full Biotin & Collagen Shampoo. The OGX volumizing shampoo takes the lead with its rich lather and deep cleansing abilities, providing immediate gratification in terms of cleanliness and efficiency in use.

Results on Hair Texture and Volume

Winner: It’s a Tie. Both products deliver results, but expectations should be managed. OGX offers noticeable volume, particularly beneficial for fine hair. The Ordinary doesn’t promise instant volume but focuses on hair strength and reduced shedding over time.

Packaging Functionality and Ingredients Insight

Winner: The Ordinary Multi-Peptide Serum for Hair Density. The clinical packaging with a practical dropper scores for precision and protection of ingredients from light. OGX loses points for lack of sustainable packaging and ingredient transparency concerns around sulfates and parabens.

Overall Experience and Value Consideration

Winner: The Ordinary Multi-Peptide Serum for Hair Density. When considering long-term value and ingredient consciousness, The Ordinary edges out with its reasonable price point for a product that supports hair health without adverse effects. OGX offers immediate benefits but falls short on the potential long-term impact due to its ingredients.

First Impressions and Packaging

Winner: The Ordinary Multi-Peptide Serum for Hair Density. The no-nonsense, science-focused packaging of The Ordinary hair care solutions speaks to those seeking efficacy without the fluff, while the tinted bottle suggests thoughtful design to preserve ingredient integrity.

Texture and Application

Winner: The Ordinary Multi-Peptide Serum for Hair Density. Its non-greasy texture that’s easy to apply directly to the scalp without mess makes it user-friendly. OGX does not compete in this category as it is a shampoo.

Results: Expectations vs Reality

Winner: The Ordinary Multi-Peptide Serum for Hair Density. Although changes weren’t dramatic, the strengthening of hair and reduced shedding gives The Ordinary an edge over OGX, which provides volume but may not significantly improve hair strength or reduce shedding.

Scent and Sensitivity

Winner: The Ordinary Multi-Peptide Serum for Hair Density. Its fragrance-free formula is ideal for sensitive users, offering a gentle yet effective approach to scalp health without the risk of irritation from added fragrances that biotin infused hair products like OGX might present.

Value for Money?

Winner: The Ordinary Multi-Peptide Serum for Hair Density. For its price point, affordable hair growth treatments like this serum offer good value as part of a comprehensive hair care routine. It supports overall hair health rather than acting as a quick fix.

In this head-to-head hair growth serum comparison, while both products have their merits, The Ordinary Multi-Peptide Serum for Hair Density comes out ahead in most categories with its gentle formula, practical packaging, and subtle yet positive effects on hair health over time.
