Making Jheri curls the classic way requires using chemicals that can cause permanent damage to your hair. If you apply the chemicals incorrectly, use too much, or overdo it in any way, your hair could become dry and brittle, and it might even break. This extreme hair damage is one reason why people stopped making Jheri curls the classic way in the mid-nineties. If you want the Jheri curl look without the harsh chemicals, skip down to the next section. You might want to consider having your Jheri curls put in at a salon instead of doing them yourself. You’re essentially giving yourself a perm, which requires some skill and knowledge of hair. Whether you have your hair done at a salon or do it yourself at home, you’ll need regular touch ups.
Perm rods come in lots of different sizes. Choose the size that you want your curls to be. Also consider the length of your hair and how long you want the curls to be when choosing perm rods.
