Best Argan Hair Oil for Thick Hair by Weight and Size

The best argan hair oil for thick hair is OGX Renewing + Argan Oil of Morocco, a 3.3 fl oz cold-pressed styling serum that lays flat over dense strands without soaking in and disappearing. If you want a single-ingredient carrier oil instead of a styling serum, PURA D'OR ORGANIC Moroccan Argan Oil in the 4 fl oz bottle is the better buy. Thick hair drinks oil differently than fine hair does, and the split between "serum with silicones" and "pure oil in a dropper" decides most of this shortlist.

Best argan hair oil for thick hair at a glance

How I screened the shortlist

I compared six argan oil listings the way a shopper would: side by side, one specification at a time. The category page bundles two very different products under the same keyword, and the first job was to sort them.

Three picks are styling serums built around cold-pressed argan oil. The two OGX bottles fall here. Three picks are pure or near-pure single-ingredient carrier oils: PURA D'OR, Cliganic, Handcraft Blends and Yoken. Both types wear the word "argan" on the label. They behave very differently on thick hair.

Screening ranked the set on five criteria, weighted in this order:

1. Fit for thick hair, judged by whether the oil coats or absorbs and how the listing describes its weight.
2. Bottle size, since thick hair uses more per application and a 2 fl oz bottle empties fast.
3. Formulation clarity, meaning whether the listing says "100% pure" or admits added ingredients.
4. Set position, so the shortlist covers every price band from entry to premium.
5. Popularity signal, used only as a tiebreaker between otherwise similar picks.

That is why the winner is a styling serum and the premium pick is a single-ingredient oil. They answer different questions, and both questions matter for thick hair.

Styling serum or pure carrier oil: which one does thick hair want?

This is the split that decides the category, and most argan roundups pretend it does not exist.

A styling serum, like the two OGX bottles, blends cold-pressed argan oil with silicones and other conditioning agents. It sits on the outside of the hair shaft, coats the cuticle, and delivers the smooth, mirror-shine finish thick hair struggles to get on its own. Frizz flattens. Flyaways disappear. The trade-off is that a serum is not the pure oil the label implies, and it can build up over time.

A pure carrier oil, like PURA D'OR, Cliganic, Handcraft Blends and Yoken, is single-ingredient argan. It penetrates the shaft, feeds the cortex, and does very little on the surface until you use enough of it. On thick hair, that "enough" is more than the label suggests, which is why the 8 fl oz bottles earn their place.

Thick hair often needs both, on different days. Pure oil goes on damp hair after washing, as a treatment. Serum goes on dry hair before leaving the house, as a finish. If you have to pick one, pick the one that solves your louder problem: frizz means serum, brittleness means pure oil.

1. OGX Renewing + Argan Oil of Morocco — Best overall

A cold-pressed argan styling serum in a 3.3 fl oz bottle that flattens frizz on thick hair better than the pure oils in this set.

Best for: thick hair that wants shine and frizz control from a styling serum Skip it if: you want a single-ingredient carrier oil with no added silicones

Thick hair rarely loses the argan oil argument on nourishment. It loses it on finish. The OGX Renewing serum lays a light film over dense strands and closes the cuticle down, which is what turns dull thick hair into shiny thick hair. The bottle holds 3.3 fl oz in a 5.8 x 1.3 x 2.25 in tube. Model number 4091614, released in 2020.

OGX says this is a cold-pressed argan oil formula, penetrating, paraben-free and free of sulfated surfactants. It positions the serum for daily use on all hair types. The listing calls it lightweight and non-greasy, which matches how a silicone-carried serum behaves on thick hair: enough slip to distribute, not so much weight that it collapses volume at the roots.

It sits at the second cheapest position in this set and sells faster than any other pick here. The trade-off against the pure oils is honest: this is a formulated serum, not raw argan in a dropper, so if you want a single-ingredient bottle you buy PURA D'OR instead.

Pros:

• Cold-pressed argan oil in a serum format
• 3.3 fl oz bottle covers weeks of daily use
• Paraben-free and no sulfated surfactants
• Second cheapest of the six here
• The fastest seller in this set

Cons:

• Not a single-ingredient argan oil
• Fragranced, which suits some scalps and not others
• 3.3 fl oz is smaller than the two 8 fl oz pure oils here

2. OGX Renewing + Argan Oil of Morocco Extra Penetrating Oil — Best budget pick

The cheapest pick in this shortlist and the sibling formula OGX pitches at damaged, over-processed hair.

Best for: over-processed thick hair on a tight budget Skip it if: you dislike fragranced hair products

This is the cheapest of the six. Same brand as the overall winner, same 3.3 fl oz bottle in a 5.95 x 1.45 x 2.35 in body, model 4091616, released in 2022. Two OGX bottles on one shortlist usually means the ranking is confused, but the two are not the same product.

OGX says the Extra Penetrating version pairs cold-pressed Moroccan argan with water-based silk proteins, aimed at weak or over-processed strands. The listing frames it around frizz control, curl definition, and repair of dry, brittle hair. It carries a citrus, floral-green, woody scent, which the listing calls out on the front of the marketing rather than burying.

For thick hair that has been bleached, heat-styled or coloured recently, this is the practical starting point. It gives you the same OGX serum behaviour as the overall pick, tuned toward damage rather than shine. Against the winner it loses a small edge on how often people buy it, and against the pure oils it carries all the same "this is a formulated serum" caveats. If your priority is cost per bottle, this is where the shortlist starts.

Pros:

• The cheapest of the six here
• Formulated around water-based silk proteins
• Cold-pressed argan oil as the star ingredient
• Paraben-free and free of sulfated surfactants
• 3.3 fl oz lasts a long time at three or four drops per use

Cons:

• Fragrance is stronger than most pure oils
• Not a single-ingredient product
• Sells slower than the overall pick even in the same brand

3. PURA D'OR ORGANIC Moroccan Argan Oil Pure Cold-Pressed — Best premium

A 4 fl oz single-ingredient argan oil that PURA D'OR flags as USDA Organic, virgin and unrefined.

Best for: thick, coarse hair that responds to unrefined single-ingredient oil Skip it if: you want the largest bottle for the money

PURA D'OR sits at the most expensive position in this set. It buys you a 4 fl oz bottle, 6 x 2 x 2 in, model 635, on the market since 2013. The listing describes the oil as USDA Organic, cold-pressed, virgin and unrefined, hexane-free, with no parabens, sulfates or synthetic fragrances. The brand adds a Climate Pledge Friendly note and says the bottle is filled in a solar-powered facility.

For thick hair, "virgin and unrefined" is the phrase that matters. A refined argan oil loses colour and scent, and often some of what a listing like this markets as active fatty acids. An unrefined oil carries a stronger nutty smell and, on thick coarse hair, coats the shaft with more perceptible substance. PURA D'OR pitches the oil as a leave-in conditioner, split-end aid, scalp treatment and cuticle oil. On the popularity signal it sells at a similar pace to the overall winner, just below it in this shortlist.

Its trade-off against the two 8 fl oz pure oils is straightforward: less oil for the highest position in the set. What you are paying for is the certification and the unrefined processing, not raw volume.

Pros:

• USDA Organic certification on the label
• Virgin, unrefined and hexane-free per the listing
• No parabens, sulfates or synthetic fragrances
• Sells at a healthy pace for a premium pure oil
• On the market since 2013, so the formula is stable

Cons:

• The most expensive pick here
• 4 fl oz is half the size of the two 8 fl oz bottles
• Unrefined argan has a stronger natural scent than serums

4. Cliganic Organic Argan Oil — Runner-up

A 2 fl oz USDA Organic argan oil in a compact bottle, best treated as a starter size for pure oil.

Best for: trying pure argan oil in a small format before committing Skip it if: your thick hair is long and you dose more than a few drops

Cliganic runs at 2 fl oz, 5.12 x 1.57 x 1.97 in, model 855102007699, released in 2025. The listing calls the oil USDA Organic, 100% pure, single-ingredient, Non-GMO Project verified, vegan and cruelty-free. It is described as sustainably sourced and minimally processed.

The reason this sits at the runner-up spot rather than higher is bottle size. Thick hair rarely gets more than a handful of applications from 2 fl oz, especially at mid-length or longer. As a first purchase to see whether pure argan works for your hair, before spending on 4 or 8 fl oz, this is the smart entry point. It falls in the mid price band, so you are not paying the premium tier for a bottle you might replace with something bigger.

The trade-off against Handcraft Blends and Yoken is the size itself. You get the same "single-ingredient pure argan" pitch, in a fraction of the volume, at a mid position on price. What you get instead is certification: USDA Organic and Non-GMO Project verified are both called out.

Pros:

• USDA Organic and Non-GMO Project verified
• Single-ingredient argan on the listing
• Mid price band with certification on the label
• Compact 5.12 x 1.57 x 1.97 in bottle travels well
• Vegan and cruelty-free per the listing

Cons:

• 2 fl oz is the smallest bottle in this set
• Thick, long hair burns through it fast
• No stated weight on the listing to compare against the rest

5. Handcraft Blends Moroccan Argan Oil — Best minimal setup

An 8 fl oz single-ingredient argan oil at the mid price band, sized for people who use oil generously.

Best for: thick hair that goes through oil quickly and wants one big bottle Skip it if: you need USDA organic certification on the label

This is the largest mid-priced pick in the shortlist. Handcraft Blends ships an 8 fl oz bottle, model argan8. The listing calls the oil cold-pressed, 100% pure, natural, paraben-free, chemical-free, cruelty-free and vegan, and describes it as derived from Moroccan argan kernels.

For thick hair, volume is the honest specification. You will apply more oil per session than a fine-hair user will, and an 8 fl oz bottle at a mid price is the setup that stops you rationing. Handcraft Blends pitches the oil as multi-use across hair, scalp, skin, nails and cuticles, which is fair for any pure argan oil in this category.

Where it trades against PURA D'OR is on certification: the listing does not carry USDA Organic labelling. Where it trades against Yoken is on popularity: Yoken shows a slower sales pace in this set. Handcraft Blends lands in the middle on both counts and delivers twice the volume of PURA D'OR and four times the volume of Cliganic. That is the case for it.

Pros:

• 8 fl oz bottle at a mid position on price
• Single-ingredient argan per the listing
• Cold-pressed from Moroccan argan kernels
• Paraben-free, cruelty-free and vegan
• Works across hair, scalp and skin

Cons:

• No USDA Organic certification stated
• Listed weight of 0.24 g looks like a data error
• Compact listed dimensions do not match an 8 fl oz bottle in real life

6. Yoken USDA Argan Oil — Best for pros

An 8 fl oz cold-pressed, unrefined argan oil aimed at heavy users, priced in the premium tier.

Best for: stylists and heavy home users mixing custom masks Skip it if: you want the fastest-selling option here

Yoken ships an 8 fl oz bottle, model LWIBDY2S45. The listing describes the oil as 100% cold-pressed, pure, undiluted, non-GMO, additive-free, fragrance-free, alcohol-free and hexane-free. It positions the oil as compatible with all hair types and calls out unsaturated and essential fatty acids on the label.

The reason to buy 8 fl oz of premium pure oil is volume with quality. If you cut your own masks, mix argan into a deep-conditioning treatment once a week, or use oil daily on long thick hair, the maths starts to favour a bigger bottle even at a higher position on price. Yoken sells slower than the rest of this set, which is why the award is "Best for pros" rather than "Best overall": this is a considered purchase, not a first-time buy.

The trade-off against PURA D'OR is certification wording. Yoken says "USDA" in the product name but the listing bullets do not confirm USDA Organic in the same way PURA D'OR's do. If certification is the whole point, PURA D'OR is the cleaner label.

Pros:

• 8 fl oz bottle at a premium tier
• Cold-pressed, undiluted, hexane-free per the listing
• No added fragrance or alcohol
• Rich in unsaturated fatty acids per the brand
• Fits heavy or professional use patterns

Cons:

• The slowest seller in this set
• Certification language is less clear than PURA D'OR's
• Premium price for what is functionally the same as the mid-priced 8 fl oz option

How much oil does thick hair actually need per use?

Dosage decides bottle life, and bottle life decides which pick actually makes sense for your hair.

Fine hair often gets away with two or three drops. Thick hair rarely does. A dense, chin-length bob might use four to six drops of a styling serum like OGX to smooth ends. Long thick hair, past the shoulders, can use eight to twelve drops of pure oil for a wet-hair treatment before styling. The bottles in this shortlist range from 2 fl oz to 8 fl oz, a fourfold spread.

Rules of thumb worth applying:

• Serum on dry hair: start with two drops, rub between palms, run through mid-lengths and ends. Add one drop at a time.
• Pure oil on damp hair: double the serum dose, work through the lower two-thirds, comb through.
• Pure oil as a mask: coat generously, wrap, wait twenty to thirty minutes, wash out. This is where 8 fl oz bottles earn their price.
• Scalp use: a few drops, massaged in, once or twice a week if your scalp runs dry.

Match the format to how you use oil. A 2 fl oz Cliganic bottle is a starter. An 8 fl oz Handcraft Blends or Yoken bottle is a household supply.

What the argan label does not tell you

The word "argan" on a hair oil label is not regulated the way "USDA Organic" is. Two useful habits when you read the listings themselves:

1. Read whether the product says "argan oil" or "with argan oil". A serum with argan oil is a formulated product. A pure argan oil is not.
2. Check for "cold-pressed", "virgin", "unrefined" and "hexane-free" as separate claims. Each one narrows the processing.
3. Look for the ingredient count. A single-ingredient oil lists one thing. A serum lists many, and silicones are usually near the top.
4. Note the bottle format. Droppers suit pure oils. Pump serums suit styling.
5. Sanity-check the specifications. If a listed bottle weight looks impossibly small for a stated volume, that is a data-entry error on the listing, not a lightweight formula.

None of this decides whether the oil suits thick hair. It decides whether the product on your shelf is the product you thought you were buying.

OGX Renewing vs PURA D'OR: which one wins for thick hair?

The overall winner and the premium pick answer different questions, and picking between them takes about three minutes.

OGX Renewing is a styling serum. It sits on the outside of thick hair, adds shine, and controls frizz for a day. It is easy to use, easy to buy again, and forgiving if you use a drop too many. It costs less. The bottle is 3.3 fl oz, gone in a few months at four drops a day.

PURA D'OR is a pure carrier oil. It goes into thick hair as a treatment, feeds the shaft, and does its work over weeks rather than hours. It costs the most in this set. The bottle is 4 fl oz, gone in a similar timeframe if you use it daily as a leave-in, longer if you keep it for weekly masks.

If your problem is how thick hair looks by lunchtime, buy OGX. If your problem is how thick hair feels after washing, buy PURA D'OR. If you can spend on both, use the serum on dry hair and the pure oil on damp hair, and stop trying to make one product do both jobs.

The verdict

The best argan hair oil for thick hair is OGX Renewing + Argan Oil of Morocco, because a styling serum solves the problem thick hair actually shows up with: frizz, flyaways and dullness that resist pure oil alone. The 3.3 fl oz bottle is dense enough to last, the format is forgiving, and it costs less than four of the other five picks. It is the fastest seller in this set for a reason.

Two conditions flip that call. If you want a single-ingredient, USDA Organic, unrefined argan oil for treatment rather than styling, buy PURA D'OR ORGANIC Moroccan Argan Oil in the 4 fl oz bottle. If you use oil heavily, mix your own masks, or share the bottle across a household, buy the 8 fl oz Handcraft Blends at the mid tier or Yoken at the premium tier.

The runner-up, Cliganic at 2 fl oz, is the right first purchase for anyone unsure whether pure argan will suit their hair. It carries USDA Organic and Non-GMO Project verified on the label, in a small enough bottle that trying it is not a commitment. The budget pick, OGX Extra Penetrating, is the same brand as the winner tuned toward damaged hair.

FAQ

Is argan hair oil good for thick hair?

Argan hair oil is good for thick hair, both as a styling serum for shine and frizz control and as a pure carrier oil for treatment. Thick strands tend to look dull without a surface finish, which is what serums like the OGX Renewing formula deliver. Pure oils like PURA D'OR feed the shaft over time. Both types have a role, on different days.

Is a premium argan oil worth it for thick hair?

A premium argan oil is worth it for thick hair when the label backs up the price. PURA D'OR sits at the top of this shortlist and carries USDA Organic, virgin, unrefined and hexane-free claims. If those matter to you, and you want single-ingredient purity for treatment use, the premium tier makes sense. If you mostly want daily shine, a serum in the entry tier does the job.

What size argan oil bottle should I buy for thick hair?

The size argan oil bottle you should buy for thick hair depends on how you use it. For daily serum use on dry hair, a 3.3 fl oz bottle like OGX lasts months. For weekly pure-oil masks or scalp treatments, an 8 fl oz bottle from Handcraft Blends or Yoken is the more honest buy. A 2 fl oz Cliganic bottle suits a first-time trial before committing.

OGX Renewing or PURA D'OR: which is better for thick hair?

OGX Renewing or PURA D'OR comes down to what you want the oil to do. OGX is a cold-pressed argan styling serum in a 3.3 fl oz bottle, best on dry hair for shine and frizz control. PURA D'OR is a 4 fl oz USDA Organic single-ingredient carrier oil, best on damp hair as a treatment. Serum for finish, pure oil for feeding.

What is the biggest mistake buyers make with argan hair oil?

The biggest mistake buyers make with argan hair oil is assuming every bottle labelled "argan" is the same product. Styling serums with argan oil, like the two OGX picks here, coat the hair from the outside and contain more than one ingredient. Pure argan oils like PURA D'OR, Cliganic, Handcraft Blends and Yoken are single-ingredient. They work differently on thick hair.

Thick hair reveals its own priorities within a week of using the wrong bottle. A serum wearer with dryness at the ends realises the finish is not the same as nourishment. A pure-oil buyer chasing shine notices the mirror finish never quite arrives. Start with the problem you see in the mirror on day one, buy the pick that matches, and give it three weeks before deciding whether to add the other type as a second bottle. The best argan hair oil for thick hair is the one that answers your louder question first, and for most shoppers that is the OGX Renewing serum.
