The Philosophy
Before scissors. Before product.
Before any of it — there were hands.
Social grooming is the oldest form of care humans have known. For millions of years, our ancestors communicated trust, tenderness, and deep attentiveness through a single act: looking closely at another person, and addressing what they found there.
We have simply made it available on a sliding scale, with good lighting and a complimentary beverage.
Our Approach
Slow.
Thorough.
Manual.
At PREEN, we offer one service in its various expressions: we look through your hair and skin, carefully, with our fingers, and we attend to what we find. Nothing more. Nothing less. No heat. No product. No massage. We are not a spa. We are not a salon. We are a grooming studio.
Every session begins with a consultation. We ask you to sit. We begin at the crown. We part the hair in sections, approximately one centimeter per pass, and we inspect each area with full attention. We move behind the ears. We check the collar line. If you have authorized the extended session, we proceed to the upper back, the forearms, and — upon explicit request — the eyebrow region.
"Our practitioners do not rush. They do not chat unnecessarily. They look. They find. They remove."
Whatever is found is handled with discretion. We do not comment on findings in a judgmental tone. We simply address them. This is the practice. This is the promise.
The Menu
Services
All sessions include consultation, a filtered water or chamomile, and an evidence summary upon request.
A focused examination of the cranial and cervical region. We part the hair in systematic sections and conduct a thorough visual and tactile survey of the scalp, hairline, and neckline. Standard findings — debris, flakes, dry patches, and miscellaneous particulate — are addressed as discovered. This is our entry-level offering and the recommended starting point for new clients.
Good for those who have never been looked at. By someone who is really looking.
Our signature service. Where The Inspection surveys, The Harvest acts. Our practitioner will not only identify but extract: with fingernails, with fine-tipped implements, or using the traditional pinch-and-roll technique. Findings may include nits, dried skin formations, ingrown filaments, or things we classify simply as "matter." All extractions are performed with care. A small specimen envelope is available at no additional cost.
Clients often report a feeling they describe as "finally."
We go everywhere we are allowed to go. Scalp, hairline, temples, behind both ears, full neck (anterior upon consent), both forearms, upper back, and the inter-scapular region if accessible. We do not rush any area. Ninety minutes is what it takes to do this correctly, and we have never in six years of operation finished early and meant it.
Please arrive in a loose garment. Buttons, not zippers. We know what we're doing but we prefer not to fight the clothing.
The most primal form of bonding we know. Two people sit facing each other, and they take turns. One grooms. Then the other. Our practitioner supervises technique, gently corrects angle and pressure, and provides light instruction on what to look for and how to feel for it. Partners, close friends, siblings, and estranged relatives have all found something here that they could not find elsewhere.
Does not require that you like each other. It helps, but it is not required.
You sit. We work. No conversation, no check-ins, no narration of findings. The Trust Session is for clients who want to simply be cared for without any cognitive burden. You close your eyes. Two hours pass. You are handed a warm towel at the end and a one-page summary, sealed in an envelope, which you may open immediately or never. Many clients choose never. Many who choose never eventually choose to read it years later and call us crying.
This session fills months in advance.
Children are extraordinarily good at holding still when they trust the person doing the looking. We have worked with children from age four upward. We use only our fingers, no implements, and we narrate everything we are doing in a calm, matter-of-fact voice. Parents are present. Findings are shared openly. We consider this our most straightforward service, as children have simply not been told yet that this should feel strange.
They always fall asleep.
The Experience
What to Expect
You arrive. You are offered a drink. You fill out a brief intake form concerning sensitivities, previous findings, and your relationship to being looked at.
Three to five minutes with your practitioner. They will look at your hair in the light, make a small sound of professional assessment, and confirm the service scope.
You sit. They begin. The room is quiet. The lighting is warm and directional. You may sleep, read, or simply stare at the middle distance and feel known.
Your practitioner steps back, regards you for a moment, and indicates the session is complete. You are given a warm towel. You pay. You leave feeling, most clients report, surprisingly okay.
Marguerite · Lead Practitioner
The Practitioner
Marguerite
Delacroix-Henn
Lead Social Grooming Practitioner, Certified
Marguerite has been grooming since she was a child. She simply never stopped. While her peers graduated from the instinct, she followed it into a methodology — training for four years under an anthropologist in Lyon, observing bonobos and consulting with primatologists whose work on affiliative touch behavior she describes as "the most honest literature I've read about what we want from each other."
She opened PREEN in 2019 with one folding chair and a ring light. The waitlist reached eight months by 2021. She has since trained a small team, each of whom she has personally certified. She will not certify someone who hurries. She has failed eleven candidates on the basis of hurrying alone.
When asked what she looks for in an ideal session, Marguerite says: "Everything. I am looking for everything."

Client Voices
What Our Clients Say
"I didn't think I had anything on me. I was wrong. And I don't mean that in a bad way. I mean it in the way where you realize you've been carrying something around without knowing, and someone else sees it, and removes it, and you feel lighter. That's what happened."
"She found something behind my left ear that she estimated had been there three to five years. She said it very calmly. She removed it. She didn't show me — she asked first, and I said no — and then she put it in the little envelope. I wept on the subway home. I don't think I was sad. I think I was just grateful someone looked."
"I came with my ex-husband. We don't speak anymore but we did Mutual Grooming once at PREEN and for forty-five minutes we were, I think, the most honest we'd been in years. Not because of anything we said. Because of where his hands went in my hair and what he was looking for. I recommend it for couples on the brink."
"I came for the inspection. I stayed for the harvest. I have now been seventeen times. Marguerite knows my scalp better than anyone alive including my dermatologist who, with respect, is going too fast and looking at too many people."
Common Questions
We Get Asked
We always find something. This is not a threat. It is a fact of being a person who lives in the world, has skin, and grows hair. What we find may be small. It may be unremarkable. We will still address it with full attention. The session has value regardless of yield. Many clients report that their most meaningful sessions were the ones where the least was found, because the looking itself was the point.
We do not, as a studio policy, consume findings during sessions. Marguerite has thoughts on this topic that she has shared in interviews and which we will not reproduce here. Our findings are placed in a small glassine envelope at the client's request, discarded hygienically if not, or — in the case of The Trust Session — sealed and presented to the client without commentary. What happens after you leave the studio is not our concern.
Not by any insurer we have worked with. We have submitted claims under "preventive dermatological assessment," "manual ectoparasite evaluation," and once simply as "grooming." All were denied. We have a template letter your therapist can write positioning sessions as adjunctive somatic therapy, which has had a 19% success rate. We are proud of this number.
Whatever you want. Some clients display them. Some clients bury them. One client has a dedicated drawer. There is no correct relationship to your own findings. We offer the envelope as an act of respect — we believe you have a right to know what was on you. We do not believe you have an obligation to feel any particular way about it.
Yes. With respect to your partner: they are wrong in a way that reveals something about them, not about this practice. Mutual grooming was the primary social bonding behavior of the primate lineage for approximately 52 million years. It was replaced by language, which is a fine tool but cannot part the hair and tell you what's underneath. We have been telling people what's underneath since 2019. Your partner is welcome to join you for Mutual Grooming. Many skeptics have left believers.
Reserve Your Session
You have things
on you.
You've known it. You've felt it. A slight sensation at the crown. Something behind the ear. That area on your upper back that you can almost but not quite reach. We can help. We can do this together.
