Scalp Care in a City of Sun and Salt

The part of hair care nobody books is the scalp. People arrive with a plan for the hair itself — the cut, the color, the smoothing — and almost never mention the skin it grows out of. In Miami Beach that is backwards, because the scalp here has a harder year than the hair does.

The scalp is skin, and here it is exposed skin

Treat it as skin and most of the confusion clears up. It sweats, it burns, it reacts, and it builds up a surface layer the same way the skin on your face does.

The difference is that nobody protects it. A part line is a strip of bare skin pointed directly at the sun for as long as you are outside. A short cut is the whole top of the head in the same position, and a close fade is bare skin with no argument about it. Sunburn on a scalp is common here and almost always a surprise, and the flaking that follows a week later gets blamed on shampoo.

A hat or a sunscreen, and it does not have to be elegant. A spray or powder sunscreen made for the scalp goes on without turning the hair greasy. A hat over a part line works. Either is better than finding out on a Tuesday what Sunday did.

Salt and sweat sit there longer than you think

Hair gets rinsed. Scalps often do not, because most people wash the lengths and let the water find its own way.

Two or three days of salt water and chlorine drying down against the skin is itchy for a reason. So is the sweat of a humid week, which in this city is every week. Rinse the scalp with plain water after the beach or the pool even on a day you have decided not to shampoo, and work the water in at the roots with your fingertips rather than letting it run past.

How often to shampoo is the question everyone wants a number for, and there is no honest one. Here the number is usually higher than the internet says, because the variable is not your hair type. It is how much sweat and salt your week put on your scalp.

Buildup and dryness are not the same problem

This is the part people get wrong, and the two want opposite things.

A scalp with buildup feels coated and looks shiny at the roots, and the flakes are larger, oilier and stick together. A dry scalp feels tight and itchy, and the flakes are small and powdery. Buildup wants a clarifying wash. Dryness does not, and clarifying a dry scalp makes it worse, which is how a person ends up washing something that needed to be left alone.

Two things help either way. Do not scratch, and use fingertips rather than nails, because a scalp you have scraped will flake more next week. And give any change two or three weeks before you judge it, since the skin up there turns over on its own schedule.

If it is red, spreading, painful, or it simply does not settle, that is a dermatologist and not a salon.

Short hair shows all of it

Nothing hides a scalp like length, and nothing exposes one like a good short cut.

Mauricio Ortiz is a Senior Stylist at McAllister Spa, and men's grooming is what guests request him for. His own line about the work is that "Short-hair work is less forgiving than it looks." That is true of the cut, and it is true of everything underneath it: at that length a sunburn, a flake or a patch of buildup is visible in a way it never would be at shoulder length.

Which makes the scalp a cutting-chair subject and not only a shampoo-bowl one. On a tight cut the condition of the skin is part of the result, and a stylist looking down at the top of your head sees things you cannot see in a mirror. Men's haircuts and the rest of the cutting and styling menu are the usual place that conversation starts.

Say something before the chemistry

Color and smoothing both land on the scalp, so the time to mention its condition is before, not after.

A scalp that is sunburned, scratched raw or freshly exfoliated is a scalp that will sting, and a colorist told in advance can work off it or move the appointment. The same goes for keratin and smoothing, where heat and product sit close to the skin, and for the lightening in highlights and balayage, which is placed away from the scalp but not out of its reach.

None of that is a reason to postpone anything. It is a reason to say one sentence when you sit down.

Where this fits with everything else

Scalp care is the quiet half of the maintenance most people are already doing. Our guide to keeping hair from frizzing in Miami covers the humidity from the hair's side, and how to maintain hair between salon visits covers the weeks in between, which is where a scalp habit either exists or does not. If short hair is your situation, men's hair in Miami Beach is the companion piece to this one.

Mauricio also cuts and styles longer hair, colors, and takes keratin and smoothing, and he sees guests in English and Spanish. Conditioning treatments sit on the hair page with the rest of it. Bring the scalp up at the start of the appointment, and it stops being the thing nobody mentioned.
