Stereo Hair Salon and Barbershop Data

It is first-person video of a person doing salon or barbershop work, recorded with two calibrated cameras, with hand pose and sensor streams alongside. People reach it through several phrasings: hair cutting robot training data, stereo hair styling video, an egocentric barbershop and nail treatment dataset, or custom beauty data collection at scale. Stereo describes the capture, and MCAP describes the container. They are separate choices.

The site does not state that stereo is already running on these rows. The catalog lists a head-mounted phone or a multiview rig as the capture setup, so a stereo pair is a capture choice agreed in the skill spec and confirmed on a Spec Pilot. The data is human capture by paid, consented contributors, not robot or teleoperation data, so using it for a specific robot still needs your own retargeting step. Nothing on this page is safety, hygiene or styling guidance. Firsthand is not affiliated with Foxglove or the MCAP maintainers.

Eight, listed in lib/commercial-catalog-data.ts under the Hair Salon, Barbershop & Beauty Studio environment in the Beauty & Personal Care sector, whose examples line reads "Hair salon, barbershop, nail studio, beauty spa -- cutting, coloring, styling, nail treatments, workspace sanitation." "Cut and style hair using scissors, clippers, and combs" is described as sectioning the hair, cutting with scissors and clippers and styling it with combs and dryer. "Hair coloring" is described as mixing colour, sectioning the hair, applying with brush and foils, timing and rinsing. "Hair Cutting & Styling" is described as cutting, washing, blow-drying and styling hair in a salon or barbershop. "Hair styling" is described as blow-drying, curling or straightening hair and finishing with brushes, irons and products. "Wash and blow-dry hair using shampoo stations and a blow dryer" is described as shampooing and conditioning hair at the basin, towel drying and blow-drying with a round brush.

"Nail treatments" is described as filing, buffing and painting nails and applying gel or acrylic treatments under a lamp. "Shape and polish nails using files, buffers, and polish" is described as filing nails to shape, buffing the surface and applying polish in even coats. "Workspace sanitation" is described as sweeping hair, disinfecting tools and chairs and wiping down the station between clients. The three cutting and coloring rows are rated Hard, "Workspace sanitation" is rated Easy and the other four are Medium. All eight are Active collection, which the site defines as recording in this environment running now, so a spec can join an existing capture stream. The site states no delivered hours and no delivered stereo footage for any of the eight rows, so this page claims none.

This page is the stereo and MCAP treatment of the eight Active collection rows. The egocentric hair salon and beauty page lists all 13 rows in the environment, eight Active collection, two Ready to deploy and three Available on request, as first-person video that is not stereo as its subject. The egocentric hair coloring page covers the single "Hair coloring" row the same way. The egocentric makeup and lash application page covers three Available on request rows: makeup, eyelash and eyebrow services and basic skin and beauty treatments. This page leaves those and the two Ready to deploy rows to those pages. The site has no separate egocentric nail salon and manicure page, so none is compared here.

The stereo pet grooming page covers two Pet Grooming Salon rows in Pet & Animal Care, both Active collection, where the subject is an animal’s coat. This page is stereo capture of salon and barbershop hair cutting, styling, coloring, washing and blow-drying, nail treatment and workspace sanitation tasks on people. The first table below reproduces the eight rows, and the second sets the pages side by side.

The catalog lists "Phone (head-mounted) / multiview rig" for all eight rows. The site does not state a stereo pair for any of them. Stereo applies through the site’s general stereo offer: a stereo pair is a capture choice agreed in the skill spec and confirmed on a Spec Pilot. The catalog does not say which of its two modes applies to each row, and the site does not state capture at a customer’s own salon, so the setting is agreed in the spec.

The site describes two stereo setups and does not say which one an order for these rows uses. The hard-environments stack is a global-shutter 4K/60 head camera with a 120° lens, two 1080p/60 wrist cameras, a depth sensor at 848×480 and 30 fps, and 200 Hz 6-DoF IMUs. The off-the-shelf stereo head rig, dataset 06, is dual fisheye cameras at 1080p per eye, a 62 mm baseline, per-unit calibration, a 9-axis IMU and hand-tracking output. Camera count, resolution and frame rate for the salon rows are Not stated.

In the cutting and styling rows both hands are busy for the whole task: one holds a comb or a section of hair and the other works scissors, clippers, a brush or a dryer. The catalog itself names scissors, clippers, combs, a dryer, brushes and irons, and the tool, the hair and both hands occupy a small part of the frame at once. A stereo pair recovers depth from the calibrated frame pair rather than from a standalone depth sensor, so the geometry of the tool and the hands sits in the same capture that shows the fingers working.

A stereo pair adds depth, not a verdict on whether a cut or a style is good. The site lists no haircut, style, colour-result or nail-quality label for these rows, and none is claimed.

Each hair row gives a natural cut. The cutting rows section the hair, cut with scissors and clippers and style with combs and dryer. Hair coloring mixes colour, sections the hair, applies with brush and foils, times and rinses. Wash and blow-dry shampoos and conditions at the basin, towel dries and blow-dries with a round brush. Hair styling blow-dries, curls or straightens and finishes with brushes, irons and products.

A spec that says "style the hair" gives one long action segment. A spec that names section, cut, blow-dry and finish gives a sequence you can slice by step. Whether each of those is its own segment, and whether one section, one cut or a whole service is one episode, is a spec decision, not a default. The site does not set an episode length or a step count. Contact events can mark when a hand or a tool meets the hair or a surface, where the spec asks for them.

The nail rows are close work on a small area: files, buffers, polish, and gel or acrylic treatments under a lamp. The sanitation row is wider: sweeping hair, disinfecting tools and chairs and wiping down the station between clients. The catalog rates it Easy, and it is the one row where a stereo pair covers a whole station rather than a hand and a tool.

The site states no nail product, lamp or polish brand and no sanitation product or procedure, and it gives no nail-quality or cleanliness label. What counts as a finished nail or a clean station is Not stated and is set in the spec. This page gives no hygiene or sanitation instructions.

At a chair the hands sit between the camera and the work, and a comb, a clipper or a brush can vanish behind a finger or a section of hair. The site states that the hands occlude the work and that fingers disappear behind objects. That is why each hand joint carries a visibility flag, why contact events mark when the hand or a tool meets a surface, and why instance masks are recorded per frame.

The site says two-handed fine motion and small objects are where occlusion bites, and it states that metric depth on sub-centimetre parts is flagged rather than interpolated. Whether a hair strand counts as such a part is Not stated, and so is a mask accuracy figure for hair. The site also states that depth degrades on wet and reflective surfaces. Whether metal scissors, clippers or irons, or wet hair at the basin, count as reflective or wet is Not stated, and so is how a moving client head affects depth. A spec that needs a clear view of a cut, a section or a nail should name that step, ask for wrist views or a multiview angle, and confirm it on a Spec Pilot.

Salon work puts a second person, the client, in frame at close range, and in the hair rows the head is the work surface. The site states a consent chain for contributors, not a separate process for a salon client, and it does not say whether a client is in frame for a given row, so how a client’s consent is handled is Not stated and has to be settled in the spec before capture. An undocumented bystander is a stated reject criterion.

For every delivered episode the site states that faces, plates and screens are detected and irreversibly blurred at ingest, that a reviewer confirms the result before anything ships, and that footage that cannot be de-identified is discarded. The anonymization record ships with the data, and every episode links to a signed contributor release through a documented consent chain. The site names no salon, barbershop, nail studio, city or region and lists capture at a customer’s own facility as not offered, so this page claims neither. Tool and chemical safety is Not stated: the site gives no contributor safety protocol, injury-prevention guidance or certification for any salon row, so this page describes none and gives no safety instructions. This is not legal advice, and the executed agreement controls.

Hair types and lengths, hairstyles and technique labels, product and chemical names, colour formulas, tool and machine brands, nail products, lamp types, cycle times, error rates and what a correct or finished service means are Not stated. They are set in the written spec, and this page claims none of them. The catalog lists no row that names shaving or beard work, so none is claimed.

MCAP is an open source container file format for multimodal log data, supporting multiple channels of timestamped pre-serialized data. It is serialization-agnostic, so messages can be Protobuf, DDS (CDR), ROS, JSON and more. Its design is row-oriented and append-only, it stores schemas alongside the data, and it offers an optional index plus optional LZ4 or Zstandard chunk compression.

Reader and writer libraries exist for C++, Go, Python, Rust, Swift and TypeScript, and the mcap CLI can inspect, merge and split files. The foxglove/mcap repository is MIT-licensed; that is the MCAP project licence, not the licence of a Firsthand delivery. The MCAP hub page and the glossary entry cover the format in full.

Firsthand offers MCAP delivery, and dataset 06 is stated as shipping as MCAP. For these rows the site states hand pose, a stereo-derived depth stream with confidence maps, IMU, contact events, action segments, per-frame instance masks and one task instruction per episode elsewhere. What it does not state is which of those are channels in an MCAP file, how they are named, what encoding they use or at what rate.

No topic name, message schema or rate is stated on this page, and none should be assumed. Name the streams that matter in the skill spec and confirm them on a Spec Pilot batch. The fourth table below sets each stream beside what the site states about it.

Hand occlusion by the comb, the tool and the hair is the first risk, under the visibility flag above. Two-handed fine motion with thin hair strands and small tools is the second, and how often it leaves the frame is Not stated. Calibration is measured at the start and end of every session under a 0.28 px RMS gate, and an episode is rejected for a sync breach beyond the ceiling for more than three consecutive frames, for the manipulated object out of frame for more than 15 percent of the episode, for an undocumented bystander or for a mismatch against the named skill spec.

A reject log ships with every batch, and rejected items are recaptured at the provider’s cost. The fifth table below lists the failure modes beside what the site states.

The October 2026 off-the-shelf catalog lists ~324,800 hours across 18 datasets, of which stereo is ~64,800 hours across 9 datasets. One dataset names this setting: M2 (~50,000 hours; commercial and industrial, with salon and spa services among the listed settings; RGB video; Latin America led). It is mono, not stereo, and it does not name barbershop, nail or hair-coloring tasks. No listed stereo dataset names salon, barbershop or nail work, so for stereo capture of these tasks this is custom collection, not an off-the-shelf purchase.

It is custom collection at scale through a network of thousands of capture providers, for a consistent, recurring data flow to labs. Where coverage is deep, the median time from signed spec to first validated batch is a median of 48 hours; where it is thin, turnaround runs three to four weeks. The site does not say which applies to the salon rows, so the timeline is quoted against your spec. Collections are billed per validated hour, and rejected episodes and recaptures are never billed.

Describe the tasks and where each starts and ends: sectioning and cutting, colouring, washing and blow-drying, styling, filing and polishing nails, or wiping down a station. Say whether an episode covers one section, one cut or a whole service, what counts as the object and what counts as a finished step, the setting and lighting, the privacy rule for the salon and for any client in frame, and name the variation your pipeline is missing. Then name the streams you want in the file, the topic naming and message encoding your reader expects, whether calibration ships inside the file or beside it, and whether MCAP is the only delivery or sits beside RLDS, LeRobot or WebDataset.

Most programs begin with a Spec Pilot, a small first batch that proves the spec and accept criteria on real footage before you scale. The sixth table below shows what each spec element decides.
