Coily (type 4)
Coily and type 4 hair is bought as its own category here
A butter made for 4C hair and a mousse made for 2B hair are not the same purchase. Kurli sells the coily category on its own so a type 4 formula is never shown to a type 2 audience.
Kurli sells placement for coily and type 4 hair as its own category, separate from curly. A brand formulating for tight curl patterns can buy the coily slot without paying to reach type 2 and type 3 users its product was never made for. The options are a direct affiliate deal, a paid featured placement in the coily category, product seeding for an honest review, and newsletter or try-on sponsorship. Write to hello@kurli.me or use the form at kurli.me/for-brands.

Why type 4 gets its own category
Most beauty placements treat textured hair as one audience. That is convenient for the seller and expensive for the buyer.
A product built for 4C hair usually assumes tight coils, high shrinkage, and a strand that dries out fast because scalp oil struggles to travel down a sharply bent hair. A product built for 2B waves assumes almost none of that. Putting both in front of the same audience means half the impressions are wasted in each direction, and the brand with the heavier formula usually takes the worse hit, because a rich butter on loose waves produces a visibly bad result rather than a neutral one.
So Kurli splits them. The coily and type 4 guide is a separate page from the curly guide, the analysis distinguishes them, and the placement is sold per category. If your formula is for tight coils, you can buy only the audience it works on.
What Kurli covers for coily hair
The standing pages relevant to this segment are the coily and type 4 guide, the hair type chart covering type 2 through type 4, frizzy and dry hair, hair porosity, and hair density and thickness.
Porosity matters commercially here more than in any other segment. It decides whether a product sits on the strand or sinks into it, which decides whether a customer says the product is amazing or says it did nothing. A brand whose formula is built for high porosity hair can say so in the placement copy, and that single line does more for the match rate than any adjective.
On the styling side, the guides cover the cuts and shapes coily hair actually gets asked for, which is what determines the product categories a user is shown next. Someone keeping a defined wash-and-go needs different products from someone in braids or a protective style, and the routine reflects that.
Shrinkage, length, and why the try-on matters in this segment
Coily hair can shrink by half its wet length or more as it dries. That single fact causes more disappointing haircuts than anything else, because a length agreed while the hair was wet and stretched is not the length that appears the next morning.
Kurli's try-on renders a chosen style onto the user's own photo before they commit. For a type 4 user that is the difference between imagining a shape and seeing it. For a brand, it matters because the product recommendation lands immediately after that moment, when the person has just decided on a specific look and wants to know what maintains it.
We would rather you judge the rendering yourself than take our word for how it handles tight coils. Open the try-on, run it, and see what it does. If it is not good enough for your brand to sit next to, tell us and do not book.
Product categories that fit this segment
The routine Kurli builds names categories, and those categories are where a product can sit. For coily hair the usual set is a gentle cleanser or co-wash, a rich conditioner, a leave-in, a cream or butter for moisture, a gel or definer for hold, an oil to seal, and a tool such as a wide-tooth comb, a diffuser, a satin bonnet, or a microfibre towel.
The accessory categories are worth naming because brands often forget them. Bonnets, satin pillowcases, and diffusers are cheap, they are genuinely part of the routine, and they have far less competition in the recommendation slot than another leave-in does.
Protective styling is its own space. If your product supports braids, twists, locs, wigs, or extensions, say so, because the recommendation logic treats those differently from a wash-and-go and the wrong pairing is obvious to the reader.
What we will not claim about this audience
We will not tell you that Kurli's audience is majority type 4, or majority anything, because we have not measured it in a way that would survive you asking how. If you want a number about this segment, ask, and you will get what the analytics reports along with the date and the tool. If we do not have it, you will be told that instead.
We will not describe an untested product as tested. Kurli's AI product suggestions are generated by category and labelled as starting points. A tested verdict exists only where a person used the product on the hair type it targets, and that is a seeded review.
We will not write a review that only says positive things. If a butter leaves a grey cast on 4C hair, the review says so, and you will be told before it publishes.
Getting the brief right
The most useful enquiry names the curl range precisely. 4A to 4C is a wide span, and a product that performs on loose coils can fail on tightly packed ones.
Tell us the porosity the formula assumes, whether it is built for wash-and-go or for protective styling, and whether it is meant to be used alone or as the third step in a routine you also sell. That last one changes which slot makes sense and often changes the recommendation from placement to a seeded review.

Questions
Questions brands ask
Does Kurli treat coily and curly hair as one audience?
No. Coily and type 4 hair is a separate category from curly on Kurli, with its own guide page and its own placement slot. A brand can buy the coily category without paying to reach type 2 and type 3 users.
How do I get a type 4 product recommended by an AI hair tool?
Contact the tool and ask about a product partnership. On Kurli that means one of four options: an affiliate deal using your tracking links, a paid featured placement in the coily category, product seeding for a tested review, or newsletter and try-on sponsorship. Enquiries go to hello@kurli.me.
Can I buy only the 4C audience rather than all of type 4?
Placement is sold at the coily and type 4 category level rather than split down to 4A, 4B, and 4C. What you can do is state the curl range your formula performs on in the placement copy, so the reader self-selects. Tell us the range in your enquiry and we will tell you whether the fit is close enough to be worth booking.
Does Kurli's audience include people wearing protective styles?
Kurli's guides cover protective styling alongside wash-and-go looks, and the product routine changes depending on which one the user picked. If your product supports braids, twists, locs, wigs, or extensions, say so in your enquiry so it is matched to those users rather than to wash-and-go users.
How well does the AI try-on handle tight coils?
Judge it yourself before you book rather than taking our word for it. Upload a photo with tight coils at kurli.me/try-on: the face-shape read and the top style pick are free, and your first render onto that photo is sold at a small intro price. If the rendering is not good enough for your brand to appear next to, tell us and do not buy the placement.
What accessory products fit this segment?
Bonnets, satin pillowcases, wide-tooth combs, diffusers, and microfibre towels all appear as real steps in a coily hair routine, and they face far less competition in the recommendation slot than another leave-in does. Accessory brands are welcome to enquire.
Will you say how many type 4 users Kurli has?
Only if we have measured it in a way that stands up to being questioned. We do not publish audience figures on the site. Ask in your enquiry and you will get what our analytics reports, with the date and the tool it came from, or a plain statement that we do not have that breakdown.
Is a seeded review better than a placement for a type 4 product?
Often, yes. Type 4 shoppers read reviews closely because a bad match is expensive and hard to undo. A tested review gives room to explain porosity, curl range, and how the product behaves, which a one-line product slot cannot do.
What happens if the review finds the product does not work?
It gets published with that finding, and you are told what it says before it goes live. You do not get approval over the wording. A review that can only be positive has no value to a reader, and readers are the reason the placement is worth anything.
Can a Black-owned or independent brand afford this?
The affiliate option costs nothing up front and pays only on tracked sales, which makes it the usual starting point for a smaller brand. Seeding costs the product and shipping. Paid placement is the only option with a fee before results, and it is quoted per enquiry rather than fixed, so tell us your budget and we will tell you plainly whether it is workable.
