What happens when you perm your hair

PERM.To some hair dressers it's a four letter word. Have you ever noticed that their face scrunches and they say ”you don't want to do that to your hair”. Why? Perming is still one of the harshest things you can do. Lets compare it to spaghetti. Your hair is the spaghetti, the  boiling water is the perm. When you toss the dried pasta in the water, the heat softens the pasta. That's what the perm solution does to your hair, softens it around the perm rod. You could take the cooked spaghetti and form it into new shape. When it dries it would stay in the shape you formed but would not be as strong as the uncooked pasta. It would be brittle and dry. The neutralizer part of the perm hardens the hair around the rod. Like the cooked pasta your hair will be drier and brittle. You can get a perm, but know that some damage is unavoidable. Consider trying different products to add more volume. Perm curls never look like natural curls. If you color your hair consider not perming. Maybe this will explain some of the reasons hair dresser don't always love perms and what happens to your hair when you do.
