Straightment for Men
Takes the fight out. Bulk, frizz and the sides that stick out are relaxed so the hair falls where the cut puts it — not poker-straight, not shiny, just manageable. Finished deliberately natural, so nobody can name what you have had done.

no line — your cut removes it
What I promise
The three numbers, honestly
Shorter, cheaper and less committing than you are probably expecting.
Salon time
1 – 2 hours
Top only on short hair is the quickest thing I do. All over and longer takes longer, but this is nothing like the half-day people imagine.
How much it takes out
Volume 60–80% · frizz 80–90%
On men the win is almost always bulk rather than curl. The hair stops fighting the cut, the sides lie in and the crown behaves. Curl is softened, not removed — you keep looking like yourself.
How long it lasts
Around 2 – 3 months
Shorter than the same treatment on long hair, and not because it is weaker — because you are cutting every few weeks, so the treated hair is leaving your head continuously. Which is also why men never get the awkward grow-out phase: there is no hard line and no shelf, the haircut removes it before it can become one.
What it actually does
It reduces bulk, not identity
The active works inside the hair and heat sets the new shape. What comes out is hair with less mass and less resistance — it goes where the barber put it and stays there between cuts.
Finished natural, on purpose
On women I finish polished. On men I deliberately stop short of that. Shiny, flat, obviously-treated hair is the failure mode here, and avoiding it is most of the skill.
It works with your cut, not against it
Short hair is denser at the crown and cut to a shape, so it is treated to sit inside that shape rather than to hang. Better cut afterwards, on the new texture — £89.95 on the day against £165 on its own.
Natural is the whole brief. Every time.
Every man who sits down here gets the same instruction from me before he gives me his: this has to look like your hair. Not treated hair, not styled hair, not hair that has obviously had something done to it. Your hair, on a day when it happened to behave.
That is not a preference, it is how I work on men without exception. On women I finish polished, because polished is usually what is wanted. On men I deliberately stop short of it — I leave texture in, I leave a little movement, and I stop well before the point where it reads as a treatment. Shiny, flat, uniform hair is the failure mode in men's work, and avoiding it is most of the skill.
It is also why I would rather do slightly less than slightly more. You can always come back and have it taken further. You cannot un-flatten hair that has been overdone, and every man who has ever been overdone remembers it.
In the chair
What actually happens on the day
1 · Read and clarify
Pattern, frizz, damage and history, then a clarifying wash. Product build-up is heavier on short hair than most men realise, and nothing works through it.
2 · Apply and develop
Section by section, timed to the hair. Short hair develops faster, which is part of why the appointment is short.
3 · Dry and direct
Dried in with direction — the sides in, the crown down, the top where your cut wants it. This is where the result is decided.
4 · The iron
Thin sections, controlled heat. On short hair this is precise work close to the scalp, and it is where a careless operator burns people.
5 · Nothing is rinsed out
No neutraliser and no rinse. It goes home in your hair and keeps settling.
6 · Your first wash — at home
Warm water, mild shampoo, dried smooth. Forty-eight hours recommended; same day possible and I will tell you which yours is.
What you actually get
Stop fighting it
Hair that goes where the cut puts it, first time, without a hairdryer and three products that give up by lunchtime.
2 minNot fifteen
Wash, rough dry with a towel, out of the door. No technique to learn and nothing to buy.
Nobody can tell
People tend to say you look well rather than ask what you have had done. That is the entire brief.
Your cut removes it
Most of the treated hair goes with your next few haircuts, so there is no grow-out problem to manage.
Who it suits — and who it does not
Ideal
W7 – C5 · sides that stick out, crown that will not lie
Medium to thick wavy or curly hair worn short, where cutting it shorter has made it worse rather than better.
Very good for
C4 – Z1 · and coarse greying hair
Tight curl and Afro texture where the complaint is bulk and drying time, and hair that has gone wiry since the grey came in — genuinely different hair that stopped behaving the way you were used to.
Usually no
Damage at DD · or when a cut is the real answer
A good proportion of the men who ask me about this do not need chemistry — they need a different cut, or the one they have, three weeks ago. If that is you, that is what I will say, and it will cost you nothing to find out.
Book a mini consultation →Whatever it is called elsewhere, this is the category.
Men's keratin · Men's relaxer · Down perm · Japanese straightening · Hair smoothening
London’s booking sites list most of these as “Ladies –” by default, which is why the majority of men have never been offered any of it. The chemistry has never cared about that.
Straightment is my own system. Read the complete guide — free, and it holds nothing back.
Colour
When to do your colour
The single most common mistake, and the one that costs the most to undo. Colour and smoothing chemistry pull against each other — the order matters, and it is not the same order for every version of this treatment.
If we use a keratin or protein system
Colour first
Colour before the smoothing, or the same day immediately before it. Once the cuticle is sealed down, colour struggles to get in and takes unevenly.
If we use an acid or plastia system
Colour after
Acid plus heat can lift the hair one to three shades and pull warmth through a toner. We treat first, let it settle, then colour to the shade you actually end up with.
Bleach and highlights
The real conversation
Bleach is not colour — it is damage with a colour result. Tell me the bleach history before anything else, including work done years ago. It is still in there.
Which system yours needs is decided at the consultation — so the honest answer to “should I colour first?” is ask me before you book the colour, not after.
Skin test
I do not routinely do one for straightening or perming, and there is no blanket UK requirement for these services — it is the product manufacturer and the insurer that drive it, not the law. Where a specific product calls for one, I will tell you and we will do it. Hair colour is a different matter: there it is effectively mandatory.
Strand and elasticity testing
Also not routine. I read the hair at the consultation and again on the day. Where I judge it necessary, I will say so before we start — and we test before anything else happens, rather than finding out halfway through.
What actually protects the hair
Knowing what has already been done to it. Colour history, previous chemistry and how it was cared for tell me more than any test — which is why I ask for the history before I ask what you want.
Making it last
The first 48 hours
Recommended, not compulsory. Leaving the shampoo out for 48 hours gives the best result — but washing the same day is possible, and I will tell you honestly whether yours needs the wait. A soft tie is fine; what marks it is anything tight, a hard clip, or hair jammed behind your ears for hours.
What you wash it with
You do not have to give up lather. The rule is not “no sulphates ever” — it is no harsh ones. A gentle sulphate cleanser is fine; heavy strippers and salt-loaded formulas shorten the result, and washing daily shortens it further. Two or three mild washes a week is the whole of it.
Not sure about the one in your shower? Send me a photo of the ingredient list and I will tell you whether to keep it — whether you booked with me or not.
London water
Thames Water classifies its entire supply as hard. Peer-reviewed work shows chemically treated hair binds considerably more mineral than untreated hair, because processing creates the sites minerals attach to — and that build-up stiffens the fibre and costs you the finish. A periodic chelating wash addresses it.
The terms, plainly
The same glossary appears on every treatment page here, so the language means the same thing wherever you read it — with what each term means for this particular treatment underneath.
pH
The acid-to-alkaline scale. Hair sits at about 4.5–5.5, slightly acidic. Alkaline products swell and open the cuticle so chemistry can get in — more change, more cost to the hair. Acid products close and smooth it — gentler, shinier, less penetration.
On Straightment for Men: acid-side, as the full treatment. Short hair sits closer to the scalp, so control matters more than strength.
Disulfide bonds
The strong, permanent sulphur-to-sulphur links. They give hair both its strength and its bounce. Hydrogen bonds, by contrast, are weak and temporary — broken by water and heat, which is why a blow-dry drops in the rain.
On Straightment for Men: a proportion loosened and heat-set. Enough to take the bulk out — not enough to make it look done.
Porosity
How easily hair absorbs and holds water and chemicals. High porosity means a raised, damaged cuticle: it soaks product up fast and processes quickly and unevenly. Low porosity is resistant and needs more time.
On Straightment for Men: short hair carries more product build-up than most men expect, which is why the clarifying wash is not optional.
Bounce (elasticity)
The ability to stretch and spring back, governed almost entirely by disulfide bond health. You can impose a shape on almost any hair. You cannot impose bounce — it has to be earned from healthy bonds.
On Straightment for Men: reduced on purpose, because bulk is the complaint. Enough is left that the hair still moves.
Reduction and neutralisation
The two-step chemistry of any perm or relaxer. Reduction breaks the bonds so the hair can be reshaped; neutralisation reforms them in the new shape and locks it in.
On Straightment for Men:not how this works. No neutraliser, nothing rinsed — it goes home in your hair.
Processing time
Timed to the hair, not to a clock on the wall. Porosity, texture and history all change how fast a treatment develops.
On Straightment for Men: one to two hours. Top only on short hair is the quickest work I do.

Start here →Questions people actually ask
Will it be obvious?
No — and if it were, I would have done it badly. Natural is the brief on every man I treat, without exception. It should look like your hair on a day it happened to behave, and I stop well short of the point where anyone could name what was done.
Will it look like a woman's treatment?
The chemistry is the same. The way I work it is not: polished on women, deliberately natural on men. Short hair is also denser at the crown and cut to a shape, so it is treated to hold that shape rather than to hang.
How long will I be sitting there?
Top only on short hair is the quickest work I do. You will get the exact time when you book, not a vague estimate.
What happens when it grows out?
Nothing dramatic. No hard line, no shelf — and since you are cutting every few weeks, most of the treated hair leaves with the cut.
I am thinning. Is this a bad idea?
Thinning hair is usually fine hair, and fine hair is more fragile — exactly the case where I want to see it before promising anything. Sometimes it is a straightforward yes; sometimes the answer is no chemistry at all.
Am I going to sit in a room full of women?
It is a spacious, comfortable, quiet salon in the middle of Mayfair, strictly by appointment — so you are expected rather than queuing. Men book here all the time.
Can I have a haircut at the same time?
Yes, and it is better done afterwards on the new texture. £89.95 with a treatment against £165 on its own.
Does it damage my hair?
Anything that changes the shape of hair is doing something to it. At the right strength on hair that can take it, condition usually improves — because you stop attacking it with heat every morning.
