Why pigment is diagnosed first
Almost everything that decides how a semi-permanent brow turns out is settled before a shape is drawn — in the reading of your own brow growth and the skin under it. This guide covers what is looked at, what each finding predicts, and why the shape is the last decision rather than the first.
The brow is read before the shape is discussed
The first thing looked at is not the brow you want. It is the brow you have, read dry and bare, with no brow makeup on it at all.
Three things are established in that first look. Which direction your own hair grows in and how dense it is, because the strokes have to follow it rather than cross it. Where the gaps actually sit, which is rarely quite where a guest describes them. And how different your two brows genuinely are — one smaller, one sparser, one sitting higher — because that difference is the work, not the shape.
Then the skin under the brow is read: whether it is behaving oily or dry, and how large the pores are. That is not a cosmetic detail added at the end of a consultation. It is the single strongest predictor of whether the pigment stays where it is put, and it is the reason two guests can have the same brows, the same appointment and completely different results a year later.
Only after all of that does anyone talk about shape. Doing it the other way round — agreeing a shape and then discovering the skin will not hold it — is how this treatment goes wrong, and it goes wrong slowly enough that nobody notices until six weeks later.
-
Read dry, and bare
No brow makeup. Growth direction, density and the real position of the gaps come first.
-
The difference is the work
How far apart your two brows already are is what the appointment is actually solving.
-
Skin predicts retention
Oily or dry, small pores or large — this decides how long the pigment stays where it was put.
-
Shape is decided last
Agreeing a shape before reading the skin is how the treatment fails six weeks later.
Why the reading decides more than the drawing
Because pigment placed in skin behaves according to the skin, not according to how well it was drawn.
Normal-to-dry skin with small pores is the easy case and the predictable one: the cuts stay clean, the pigment settles, and the strokes heal crisp and hair-like. Oily skin is the difficult case — strokes spread into one another, the brow reads blurry rather than as individual hairs, and the pigment fades faster than on any other skin type. Large pores push the same way, and so does heavy daily sweating, which is why anyone who trains every day is asked about it.
That reading is what makes the honest answer possible. On very oily, very porous skin, the answer here is that this is not the right treatment — not a booking with a caution attached to it. On moderately oily skin, the answer is a plan with what to expect stated plainly. The reading is what separates those two, and no amount of skill at the drawing stage substitutes for it.
The brow itself is graded for difficulty in the same conversation, and you are told which kind you have. A brow that still has natural hair in it, where the job is filling gaps, gives the most natural result and is the safest work done here. A brow with almost nothing on one side and density on the other, or a brow bone that sits asymmetrically, makes symmetry the hard part — and difficulty stated at the reading is information, while difficulty discovered at the mirror is a complaint.
-
Dry to normal heals crisp
Clean cuts, settled pigment, strokes that still read as separate hairs.
-
Oily spreads and fades
Strokes run into each other, the brow reads blurry, and the colour goes first.
-
Daily sweating shortens it
Heavy sweating and daily gym are asked about because retention drops.
-
Difficulty is stated upfront
One bare side or an asymmetric brow bone makes symmetry hard — you hear that first.
Reading one · Your own growth
Direction, density and where the gaps really are
The strokes have to travel the way your hair already travels, so the first reading is of the hair rather than of the outline.
-
Which way the hair grows
Brow hair does not grow in one direction across the whole brow, and strokes placed against it are what make a result look drawn on. The direction is read section by section before anything is mapped, and it is read dry — brow makeup hides exactly the thing being looked for.
-
Where it is dense and where it is not
Density decides how much work each part of the brow needs, and gaps are rarely exactly where a guest points. Reading them properly is what allows the strokes to be concentrated where they are actually missing rather than spread evenly for the sake of it.
-
How far apart your two brows are
One brow smaller than the other is one of the commonest reasons guests come, and it is read carefully rather than assumed. It is also the finding that sets how difficult the job will be, because bringing two very different brows close is harder than filling two similar ones.
The limit of this reading: it tells us what can be built. It does not tell us whether the skin will keep it.
Reading two · The skin under it
Oily or dry, and how large the pores are
This is the reading that predicts the result a year out, and it is why the skin question is asked before the shape question.
-
Normal to dry, small pores — the easiest case
Here the cuts stay clean, the pigment settles where it was placed, and the strokes heal crisp. It is the most predictable skin to work on and the one that holds the result longest, and it is what makes a healed brow still read as individual hairs rather than as a shaded shape.
-
Oily, large pores — the hardest case
Strokes spread into each other, the brow heals looking blurry rather than hair-like, and the pigment fades faster than on any other skin. On very oily and very porous skin the treatment is declined here rather than attempted, and on moderately oily skin what to expect is said plainly before you decide.
-
Heavy sweating, which behaves like oily skin
Anyone who trains hard every day is asked about it, because heavy sweating shortens retention in the same direction that oil does. It does not rule the work out on its own; it changes what is promised, and it makes the healing week harder to get through cleanly.
-
And whether you will follow the aftercare
The cleanest heals happen on dry-to-normal skin with small pores, on guests who intend to follow what they are given. That last part is not a character judgement — it is a scheduling one, and it is worth being honest about before booking rather than after.
The limit of this reading: skin type can be worked with, but it cannot be argued with. It sets the ceiling on the result.
Reading three · What stops it here
The findings that end the reading rather than shape it
Some findings change the plan. These end it for the day, or until something else has been dealt with.
-
Anything active on the brow area
Active acne, eczema, psoriasis, any rash and fresh sunburn on the brow area are not worked over. The skin is settled first and the appointment is moved — and if the skin is not ready on the day, no work happens on the day.
-
Old permanent makeup, and old faded tattoos
A brow that already carries permanent makeup, especially one that has faded brown or blue, is not a base to build on. It needs removal or correction before new strokes go in. Working straight over old pigment has never produced a result worth having, and a guest who asked for exactly that here was sent for correction first.
-
The history that belongs to a doctor, not a brow
Blood thinners and aspirin, an oral acne medicine finished within the last six months, uncontrolled diabetes, blood disorders, autoimmune conditions, a tendency to keloid scarring, any skin allergy, and pregnancy or breastfeeding all change the answer. They are asked about by name, and the detail of what each one means is set out in the suitability guide.
The limit here: none of these are permanent refusals except where a doctor says so. Most are a wait, and the wait is stated with its reason.
After the reading · Mapping
Only now is a shape decided
Mapping is where the reading becomes a shape, and it is the stage most worth understanding before you sit in the chair.
-
Built with your brow bone, never against it
Your eye shape and the balance of your face are read alongside it, but the natural position of the brow bone is what the shape is built with. Forcing a requested shape against it is the commonest beginner mistake in this trade, and it produces a brow that never quite looks like it belongs to the face it is on.
-
Measured, not matched by eye
Symmetry judged by eye is how two brows end up different. The mapping is done by measurement, and it is done with you sitting upright rather than lying down, because a face sits differently when you stand and a shape mapped flat rarely survives the mirror.
-
The start point and the arch matter most
Those two are what an eye notices instantly if they disagree between the brows. A small difference at the tails is tolerable and often unavoidable; a difference at the start or at the arch height is the one everybody sees, so those are matched first and most carefully.
-
Approved by you, in a mirror, before the first cut
Nothing is finalised without that approval, and mapping is never hurried to save time — ten minutes saved there is paid back over ten weeks, because a cut once made does not come back. The pigment undertone is decided for your skin at the same stage rather than taken from a tray, since the wrong undertone is what makes a healed brow read greyish or blue instead of warm.
The limit of mapping: it can bring two brows close. It cannot make two brows identical, because no face is symmetrical.
What goes wrong before a single stroke is placed
Every one of these happens at the reading or the mapping stage — which is exactly why those stages are the slow ones.
-
Agreeing a shape before anyone has looked at the skin.
Instead
Read the skin type and pore size first. It predicts the result more reliably than the drawing does.
-
Building the shape the guest asked for, against her own brow bone.
Instead
Build with the brow bone. A shape fought onto the wrong bone never reads as part of the face.
-
Matching the two brows by eye because they look close enough.
Instead
Measure. Eye-matching is how the start points and arch heights end up visibly different.
-
Mapping the shape while the guest is lying back in the chair.
Instead
Map sitting upright. A face sits differently standing, and a flat-mapped shape rarely survives the mirror.
-
Reading a brow that still has brow pencil or powder on it.
Instead
Read it dry and bare. Makeup hides the growth direction and the real position of the gaps.
-
Laying new strokes over old permanent makeup to cover it.
Instead
Remove or correct the old pigment first. Working over a faded brown or blue tattoo has never worked.
-
Shortening the mapping because the day is full.
Instead
Give it the whole time it needs. Ten minutes saved at mapping is paid for over ten weeks.
Questions about the reading
The treatment page covers what microblading involves. These are the ones about what is looked at first.
Why does my skin type matter for a brow treatment?
Because pigment behaves according to the skin it is placed in. Normal-to-dry skin with small pores keeps the cuts clean, lets the pigment settle and heals the strokes crisp; oily skin with large pores lets the strokes spread into each other so the brow reads blurry rather than hair-like, and it fades faster than any other skin type. Heavy daily sweating does the same. It is the strongest single predictor of your result, which is why it is asked about before the shape is discussed rather than after.
Why am I asked to come without brow makeup?
Because the reading is of your own hair, and makeup hides exactly what is being looked for — which direction the hair grows in, how dense it is in each part of the brow, and where the gaps genuinely sit rather than where they appear to. The brow is read dry and bare for that reason, and it takes a couple of minutes.
Which brows are easy to improve, and which are difficult?
The easy case is a brow that still has natural hair in it where the job is filling gaps — that gives the most natural result and is the safest work of the lot. The difficult case is a brow with almost no hair on one side and density on the other, or a brow bone that sits asymmetrically, because then symmetry rather than shape becomes the work. You will be told which of the two you have at the reading, not afterwards.
Can the shape in my reference photograph be copied?
It can be used as a direction, and it is genuinely useful for showing what you like. It cannot be copied onto a different brow bone: the shape is built with your own bone and your own growth, your eye shape and the balance of your face are read alongside them, and a shape forced against all of that never looks like it belongs to the face wearing it. Where the photograph is not achievable on you, you hear that at the mapping stage — before any cut, not after.
I had permanent brows done years ago — where does the reading start?
With the old pigment, and it usually ends there for the day. Old permanent makeup — particularly a brow tattoo that has faded to brown or blue — is not a base to work on; it needs removal or correction before any new strokes go in. That is the answer given here even when it costs the appointment, because laying new work over old pigment has never produced a result worth having.
Why is the mapping done sitting up rather than lying down?
Because a face sits differently when you are upright, and a shape mapped while you are lying flat rarely survives the first look in a mirror. The same reasoning governs the rest of the stage: the two brows are matched by measurement rather than by eye, the start points and the arch heights are matched first because those are what an eye notices instantly, and nothing is finalised until you have approved it on your own face.
