What's Really in Our Shampoo and Conditioner

What's Really in Our Shampoo and Conditioner

Most hair care ingredient lists fall into one of two traps. Either they're a wall of chemical names nobody outside a formulation lab can parse, or they're a vague "botanical blend" that sounds nice and tells you nothing. We think both are a little dishonest in their own way, one by overwhelming you, the other by underexplaining, and both leave you exactly where you started: trusting the front of the bottle instead of understanding what's actually inside it.

So here's the actual ingredient list behind our shampoo and conditioner, what each thing is doing, what's genuinely well-supported, and what's more of a nice-to-have than a proven active. We're also going to start somewhere most hair care content skips entirely: pH, because it turns out to be one of the more consequential and least discussed things in the whole bottle, and because the two numbers behind it are things we can actually point to a lab report for rather than ask you to take on faith.

Why pH is the first thing worth understanding

Hair, like skin, has a natural pH environment it's built to function in, generally in the slightly acidic range, and the outermost layer of a hair strand, the cuticle, behaves very differently depending on where the product you just rinsed through it sits on that scale.

The cuticle is made of overlapping scales, similar in concept to shingles on a roof. At a lower, more acidic pH, those scales lie flatter against the hair shaft, which is what produces smoothness, shine, and reduced tangling, since flat scales create less friction against each other and against neighboring strands. At a higher, more alkaline pH, the scales lift and swell open, which increases porosity, roughens the surface, and makes hair more prone to frizz, tangling, and moisture loss, since an open cuticle lets more water in and out uncontrollably rather than holding it where it belongs. Color-treated or chemically processed hair tends to be especially sensitive to this, since the cuticle is often already somewhat lifted or damaged from the processing itself, which is part of why pH-conscious formulation matters even more for hair that's already been through a color or straightening service.

This isn't a new discovery, but it's a relatively recent one in the history of hair care. Traditional bar soap, and a lot of early shampoo formulations, were meaningfully alkaline, often in the pH 8 to 10 range, because they were built primarily around cleaning power rather than cuticle behavior. The shift toward "pH-balanced" formulations in cosmetic chemistry happened specifically because researchers connected that alkaline environment to the rougher, more tangled, more damaged-feeling hair that came with regular use of those older formulas. It's a genuine example of the industry correcting itself once the mechanism was understood, rather than a marketing term invented after the fact.

Our shampoo tested at a pH of 5.84, within its 5.5 to 6.5 specification. Our conditioner tested at 5.16, within its 4.5 to 5.5 specification. Both land in the range associated with a closed, smooth cuticle rather than an open, roughened one. That's not a marketing detail, it's a measured, lab-confirmed fact about how these products are likely to interact with the actual structure of your hair, and it's the piece of information we think matters more than almost anything else on the ingredient list.

What's actually cleaning your hair

A shampoo's job starts with its surfactants, the ingredients that actually lift oil, product buildup, and dirt off your scalp and hair so water can rinse them away. This is also where a lot of "clean" hair care marketing gets vague, so we want to be specific.

Our shampoo uses a combination of what's listed as sodium cocoyl isethionate, cocamidopropyl betaine, and an ingredient derived from coconut and lactic acid in the lactylate family. Sodium cocoyl isethionate is a coconut-derived surfactant known in cosmetic chemistry for being one of the gentler cleansing agents available, producing a rich lather without the more aggressive defatting effect of harsher surfactants like sodium lauryl sulfate, which strips oil from hair and scalp more completely than most people's hair actually needs or wants. Cocamidopropyl betaine is an amphoteric surfactant, meaning it carries both a positive and negative charge depending on the surrounding pH, and it's widely used specifically because it boosts lather and mildness when paired with a primary cleanser like sodium cocoyl isethionate, without adding much cleansing harshness of its own. It shows up in a huge share of gentle and baby shampoo formulations for exactly this reason.

Here's an honesty point worth stating plainly, because it connects to something we've said elsewhere about this brand: every one of these surfactants, however they're sourced, is a manufactured, chemically transformed molecule. Coconut oil doesn't naturally lather and clean hair on its own; it has to be chemically processed, through reactions like sulfonation or amidation, into a genuinely different compound before it functions as a surfactant. Calling the starting material organic is accurate and meaningful for sourcing. It doesn't mean the finished ingredient in the bottle is unprocessed or "not a chemical." We'd rather you understand that distinction than let "organic" quietly imply something about the finished formula that isn't true, and it's the same distinction we've drawn everywhere else in this catalog rather than one we're applying selectively to hair care.

There's also a simpler, more practical reason we didn't reach for the harshest, most aggressive cleansing option available. Sulfates like sodium lauryl sulfate clean thoroughly, sometimes more thoroughly than hair actually benefits from, stripping natural oils along with dirt and product buildup and leaving both hair and scalp drier than they started. For most people washing a few times a week, a gentler system that cleans effectively without over-stripping tends to leave hair in better condition over time, which is the actual reasoning behind choosing a milder surfactant combination rather than a marketing preference for one label over another.

The moisture layer: aloe, honey, and glycerin

Once you're past the cleansing agents, the rest of the shampoo formula is built around retaining and restoring moisture, since even a gentle cleanser removes some.

Aloe vera gel is a genuine humectant with a real, if modest, research base for skin and scalp hydration and calming irritation, which is part of why it shows up across such a wide range of personal care categories, from sunburn treatments to daily moisturizers to, here, a shampoo base. Honey works similarly as a humectant, drawing and holding moisture, and carries some of the same mild antibacterial properties we've written about elsewhere in the context of our raw honey products, though at whatever concentration it's included here, its role is primarily about moisture retention rather than a standalone antimicrobial treatment for the scalp. Glycerin is one of the most well-established humectants in all of cosmetic chemistry, cheap, effective, and backed by decades of formulation research showing it reliably draws water into hair and skin from the surrounding environment. It's a genuinely unglamorous ingredient that does real, unglamorous work, and it deserves more credit than it gets simply because it isn't novel or exciting enough to headline a marketing campaign.

Hydrolyzed quinoa protein is a less common addition, and it's worth explaining what protein hydrolysates actually do in hair care generally, since the mechanism is genuinely interesting rather than just a buzzword. Hair that's damaged, whether from heat, color, or mechanical stress, develops gaps and rough spots in its outer cuticle layer. Small protein fragments, hydrolyzed down to a size that can actually adhere to or partially penetrate those gaps, temporarily fill them in, which is what produces the smoother feel and improved manageability people notice after using a protein-containing product. Quinoa protein specifically is a less commonly used source compared to the wheat or keratin hydrolysates more typical of this category, but the underlying mechanism, small peptide fragments filling cuticle gaps, doesn't depend on which plant or source the protein originally came from. This is a real, well-understood mechanism, and it's also worth being clear that the effect is temporary and cosmetic, restoring feel and manageability between washes rather than permanently repairing the hair's internal structure.

The oil layer in our conditioner

Our conditioner is built around a blend of plant oils, each with a genuine reason for being there, calibrated honestly rather than oversold.

Olive oil and camellia oil both carry a fatty acid profile dominated by oleic acid, which helps smooth the cuticle surface and adds shine, similar in concept to how we've discussed oleic acid's role in skin emolliency elsewhere. Camellia oil specifically has a long history of traditional use in East Asian hair care, valued for a similar smoothing, shine-enhancing effect, and often described anecdotally as helping protect hair from environmental dryness, though the modern clinical research quantifying that specific benefit is limited compared to how long the ingredient has been used. Sweet almond oil and avocado oil are both gentle, vitamin E-containing emollients that help seal moisture into the hair shaft; avocado oil in particular is prized in hair care for a rich, slightly heavier feel that suits drier or coarser hair types especially well, and its vitamin E content contributes some antioxidant protection against the kind of oxidative stress UV exposure and heat styling place on hair fiber over time.

Castor oil deserves a specific, honest note, since it's become one of the most hyped hair ingredients online over the past few years, often credited with dramatically accelerating hair growth. The actual clinical evidence for that specific claim is thin, largely anecdotal rather than backed by controlled human trials. What castor oil reliably does, and does well, is act as a thick, highly emollient sealant, thanks to an unusually high concentration of ricinoleic acid, higher than almost any other common carrier oil, which gives hair a smoother, shinier, more coated feel. That's a real, useful cosmetic effect. It's a different claim from "regrows hair faster," and we'd rather you know which one we're actually making.

Jojoba oil is worth a specific mention too, because it isn't technically an oil at all in the strict chemical sense, it's a liquid wax ester, which puts it in a different molecular category than the triglyceride-based oils listed above. That structural difference matters because wax esters are also a component of human sebum, the oil your scalp naturally produces, which is the same "structurally similar to what your body already makes" argument we've made elsewhere about tallow and skin. It's a genuinely interesting parallel, and it's part of why jojoba shows up so frequently in scalp-focused formulations specifically.

The actives worth a closer, more careful look

This is where evidence quality varies the most, and where we want to be the most precise.

Biotin appears in both our shampoo and conditioner, and it's worth being straightforward about it: biotin deficiency is genuinely rare in people eating a reasonably varied diet, and when hair thinning is actually caused by a biotin deficiency, supplementation helps meaningfully. But for the much larger group of people without an actual deficiency, the evidence that additional biotin, especially applied topically in a rinse-off product rather than taken orally, meaningfully strengthens or grows hair is weak. Biotin's popularity in hair care marketing has grown well ahead of the research specifically testing topical application, which is a gap worth naming rather than smoothing over. We include it because it's a well-tolerated, low-risk ingredient with a long history of use in this category, not because we think it's doing dramatic, measurable work on its own.

Panthenol, listed here as vitamin B5, sits in a more genuinely earned middle ground, and it's worth being specific about exactly which claims earn that credit and which don't. As a humectant and film-forming conditioning agent, its evidence is solid: it's water-soluble, penetrates into the hair shaft rather than just sitting on the surface, and has been shown in formulation research to reduce protein loss from processes like coloring and improve moisture retention, shine, and manageability. That's a real, well-supported cosmetic effect, and it's the reason panthenol has stuck around in hair care for decades rather than being a passing trend, closely enough associated with hair conditioning that one of the largest hair care brands in the world built its name around it. Where the evidence gets thinner is in growth or thickness claims specifically; those exist mostly in small combination-product studies where panthenol was one ingredient among several alongside things like salicylic acid or niacinamide, which makes it genuinely hard to credit panthenol alone for whatever result the combination produced. We're comfortable standing behind panthenol as a genuinely effective moisture and manageability ingredient. We're not going to tell you it thickens or regrows hair on its own, because the research that would actually support that specific claim, isolating panthenol by itself, doesn't really exist yet.

Rosemary and peppermint essential oils round out the conditioner's actives, and this is worth handling with real care because rosemary oil specifically has become one of the most repeated hair-growth claims on the internet over the past few years. The claim traces back to a single 2015 randomized trial, led by researcher Yunes Panahi and published in the journal SKINmed, comparing rosemary oil against 2 percent minoxidil in people with androgenetic alopecia over six months. Both groups showed a significant increase in hair count with no meaningful difference between them, and the rosemary group reported less scalp itching. That's a real, peer-reviewed, legitimately interesting finding. It's also a single study, and it's worth naming a specific methodological gap rather than just gesturing at "limitations": the trial compared rosemary oil to minoxidil directly, without a third, no-treatment group to confirm that either treatment was actually responsible for the change rather than some portion of it reflecting natural fluctuation over six months. That design tells you rosemary performed similarly to minoxidil in this one trial. It doesn't fully tell you how either would have compared to doing nothing at all, and it hasn't been robustly replicated at the same scale since.

Peppermint oil carries a smaller, similarly early research base, mostly around its cooling, tingling sensation and some evidence of increased local blood flow to the area it's applied to, a plausible but not definitively proven mechanism for supporting scalp health that deserves the same measured treatment as everything else discussed here.

Just as important: that 2015 study applied pure rosemary oil directly to the scalp via dropper, at a specific, concentrated dose, held in contact with the scalp rather than rinsed away minutes later. A rosemary-infused conditioner, used as a rinse-off product at whatever diluted concentration a finished formulation carries, is a meaningfully different delivery method than the protocol that single study actually tested. We include rosemary and peppermint here for their traditional use in scalp care and their pleasant, functional scent, and because they're genuinely well-tolerated ingredients with a long history of use. We're not going to tell you our conditioner replicates a clinical trial it was never tested against.

What "organic" means on this list, specifically

Every ingredient here is listed as organic, reflecting the sourcing of the raw material, and we want to be exactly as precise about that as we've been elsewhere. This describes the ingredient sourcing, not a certified organic status for the finished, blended product, and it isn't a claim that every ingredient in its finished form is unprocessed. Several of the surfactants discussed above are a clear example: genuinely derived from organic coconut sources, and also genuinely put through real chemical transformation to become the cleansing agents they are in the final bottle. Both things are true at once, and we'd rather say so than let the word "organic" do more implying than it's entitled to.

What the lab actually verified, and what it didn't

Our shampoo and conditioner were both tested by an independent lab and confirmed compliant with FDA cosmetic regulations, including the Modernization of Cosmetics Regulation Act of 2022, the most significant expansion of FDA oversight over cosmetics in decades, covering facility registration, ingredient safety substantiation, and mandatory adverse event reporting. Beyond that compliance confirmation, both products were verified on physical specifications, appearance, pH, density, and viscosity, all within their stated ranges, and on microbial safety, with total bacterial count and mold and yeast both coming back well under their respective limits on each product.

What that testing doesn't include is a clinical efficacy trial on the finished formula itself, for shine, growth, strength, or any other specific outcome. It also doesn't include an independent, published breakdown of exact ingredient concentrations, since that composition is held as confidential formulation detail, standard practice across this industry. What we've walked through here is mechanism, honestly graded by the quality of evidence behind each ingredient, not a claim that this exact bottle has been clinically measured against a specific outcome.

The honest version, all together

A pH that lands in the range associated with a smoother, healthier-behaving cuticle. Gentle, genuinely well-regarded surfactants that clean without stripping, built through real chemical processing regardless of how organic the starting material was. A moisture layer built on humectants with decades of solid formulation evidence behind them. An oil blend with real, if varying, degrees of support depending on which oil and which specific claim you're asking about. And a couple of higher-profile actives, panthenol and rosemary, that deserve real credit for what they're actually shown to do and real restraint on the claims that have grown up around them without the evidence to match, especially where a single small study has been stretched to cover a use case, a rinse-off conditioner rather than a concentrated leave-on application, that it never actually tested.

That's the whole list, explained rather than hidden behind either an intimidating wall of chemistry or a vague, feel-good "clean beauty" label. We'd rather you know exactly what you're putting on your head and why, ingredient by ingredient, than have you trust a bottle because the front of it sounds nice.
