Red flags of perming

1. High Lighted hair
If your hair is more then 30-40% highlighted you probably shouldn’t  
perm your hair. Even if it is highlighted at all, you should think twice  
because as we all know highlighting is damaging to your hair, so  
perming over bleached hair that probably has some damage to the hair’s  
cuticle will likely cause big time frizz. Plus, you will have to touch  
up your highlights 6-8 weeks down the road which will just make it  
worse. Although there are products to control the frizz, substantial 
breakage could also occur and then you’re hooped.

2. Dry hair                                                                                              

If your loaf is already dry, brittle or frizzy, a perm will dry it out even more. But if you are absolutely adamant on curling the locks, consider reconditioning treatments and or daily treatments to get your mane in shape and moisturized before the final decision of perming.

3. Lots and lots of short layers.
They might be able to pull it off as a 12 when they rock it super  
straight, but add some curls to the student style haircut and your 12  
is now a 5. Remember, curls equals volume, so if your layers hit  
around your ears and jawline, that’s where you will get your volume.

4. Colored Hair
Although not as dangerous as perming highlighted hair, if the clients  
hair is colored you may want to think twice about perming their hair. It  
is in the clients best interest to allow 2-3 weeks before and after you 
perm ones colored hair. Keep in mind that a perm will likely lighten  
your color which can cause some issues. Just remember, perming over  
colored hair is safer then perming highlighted hair, but anytime your  
hair has been previously chemically treated, a perm may cause unwanted  
damage.

As seen in the last photo the Digital Perm also called a “hot perm” uses hot rods whose temperature is regulated by a machine with a digital display. A digital perm makes the wave most prominent when the hair is dry, and loose when it is wet. Digital perms thermally recondition the hair, though the chemicals and processing are similar to a straight perm. One’s hair often feels softer, smoother, and shinier after a digital perm than before it.
