Dry Cut vs Wet Cut: Why the Salon Cuts Curls Dry
A client with curls sits in the chair, the stylist wets the hair, cuts it straight across, and the client goes home happy. Two days later the hair dries, springs up three inches, and the cut is a different haircut than the one she paid for. The problem is not the stylist's eye. The problem is the water. Wet curls stretch 30 to 50 percent longer than dry curls, so a wet cut measures a length that does not exist.
That is why curly specialists cut dry. A dry cut shows each curl as it actually falls, so the stylist cuts the length the client will see in the mirror, not the length the water is faking.
The shrinkage numbers, by curl type
Shrinkage is not uniform. Type 2 waves shrink 10 to 25 percent, type 3A shrinks 25 to 40 percent, type 3B and 3C shrink 40 to 60 percent, and type 4A to 4C shrink 60 to 75 percent. A wet cut on 4C hair can lose half its length when it dries, which is why a client who asked for a trim comes home with a haircut she did not agree to.
The stylist who cuts dry works curl by curl, cutting each one where it falls rather than pulling the hair straight and cutting a line. DevaCurl and Rezo certifications both teach the dry method, and the Rezo cut in particular is built around cutting the curl in its natural fall, layer by layer, so the shape holds when the hair is dry.
When the wet cut is still right
A dry cut is not the answer for every shape. A blunt bob, a major reshape, or a cut that needs a clean perimeter is easier wet, because the stylist needs the hair combed into a single line to see the edge. The compromise most curly specialists use is a hybrid: a wet cut for the outline, then a dry refinement once the hair is styled, cutting the individual curls that sit wrong.
The question to ask in the chair is not which method the stylist uses, but whether they have cut your curl type before. A stylist who cuts 3B hair dry every day will do a better job than a stylist who cuts 4C hair wet once a month, whatever the method. Ask how many curly clients they see in a week, and whether they cut dry or wet, before the scissors come out.
What to expect at the appointment
Come with your hair styled the way you normally wear it, clean and dry, with product in. The stylist needs to see the curls as they fall on a normal day, not as they look after a wash at the salon. Bring photos of the length you want when dry, not when wet, and point at the curl, not the mirror, when you say how much to take off.
Expect the cut to take longer than a straight cut. A curl-by-curl cut is slow work, and the stylist will cut, let the hair settle, and cut again. The result should look the same when you leave the salon and when you wash it yourself three days later, because the cut was made on the hair as it actually is.
