How Long Going Blonde Actually Takes
The question that comes before any other when someone books a first blonde appointment is how long they will be in the chair. The honest answer is longer than most people plan for, and the reasons are worth knowing, because nearly every blonde that goes wrong goes wrong in the last half hour of an appointment that was rushed.
Lightening is a process with a clock in it
Color that deposits is fast. Lightening is not. Lightener has to work through the pigment in the hair in order, and that work happens over time at a pace the hair sets rather than one the schedule sets. There is no version of it that goes quicker because the day is busy.
The hours fill up in a way that looks unremarkable from the chair. The hair is sectioned, and sectioning is the part that decides whether the result looks placed or scattered. Then it is painted or foiled, section by section, which on a full head is simply a long piece of handwork. Then it processes, and during processing it gets checked, repeatedly, because the only way to know where the hair has got to is to look at it.
Add a wash, a treatment, the toner, and a blow-dry to see what was actually made, and a full blonde appointment is most of a morning. A first one, with a consultation at the front of it, is often more.
Your hair's history sets the clock, not your hair's color
Two people can sit down with hair that looks the same and need completely different appointments. What separates them is everything that has already been done to that hair.
Box dye is the big one, because home color is built to be permanent and is often layered over itself at the roots for years. Hair that has been colored dark repeatedly does not give the lift up easily, and pushing it to do so in one sitting is how hair breaks. Old henna behaves unpredictably under lightener and has to be known about in advance. A summer of pool water leaves mineral buildup that needs clearing before any lightener goes near it.
None of this is a reason not to go blonde. It is the reason the consultation asks what looks like a lot of questions, and the reason an honest colorist will sometimes quote you a longer day than you were hoping for.
The toning is not the last five minutes
This is the part people underestimate. Getting hair light is the loud half of the appointment. What decides whether the result reads as expensive or as brassy is the toning that happens after the lift, and toning is a judgment made about the exact level the hair reached that day, on that head, under that light.
Fiona Crowley, who takes most of the blonding on our floor, puts the whole business plainly: "Blonde is the least forgiving thing a color room does." A lift that was checked carefully and then toned in a hurry at the end of a long appointment is the most common way a good blonde turns into a disappointing one.
Sometimes the right answer is two visits
If the distance between where your hair is and where you want it is large, the appointment that gets you there safely may be two appointments a few weeks apart rather than one very long one. That is not a colorist being cautious for the sake of it. Hair has a limit to how much lift it will take in a day while staying hair you can brush, and a planned second visit is how you get the color without paying for it in condition.
It is worth hearing that before you book, not at the end of the first session.
Planning the day
A few practical things make the hours easier. Come with a photo or two taken in daylight without a filter, because the words people use for blonde mean different things to different people and a photograph does not. Eat beforehand. Do not book something you cannot be late for immediately afterward, especially the first time. Bring something to do, because the processing time is real time.
Arriving with hair that was not washed that morning is fine and sometimes preferred. What matters far more is telling the colorist honestly what has been on your hair, including the box that was only used once.
Who does this here
Fiona Crowley is a Master Colorist at McAllister Spa with over a decade in the industry, and blonding and highlights are what she is requested for. She also takes color correction, which is frequently the appointment that follows a blonde done somewhere else, and she cuts and styles. She works in English.
Her profile is at Fiona Crowley. The painting and placement work is on the highlights and balayage page, and the rest of the color and cutting menu is on the hair page. If you are not sure what your hair needs, or how long it will take, that is what the consultation is for. Text (305) 604-0550 with a daylight photo and we will tell you what the day looks like before you book it.
