Q: I had my hair thermally straightened using the Japanese method. Now, I have about 4 inches of regrowth, which I usually straighten with a flat iron. Is it safe to perm my hair back to a wavy or curly texture? What would you recommend?
 
A: Based on everything I’ve learned about the Japanese Thermal Restructuring system, styling your hair afterward - including perming it - is possible. So, yes, you can perm your hair back to a wavy or curly pattern if that’s what you want.
 
Unlike hydroxide relaxers, which chemically alter the hair’s bonds in a way that can conflict with perming, the Japanese Thermal Restructuring process doesn’t pose the same risks. In fact, many of the chemicals used in both processes are similar. The most important factor to consider is the current health of your hair. Before proceeding, carefully check for any signs of damage, such as excessive dryness, split ends, rough texture, or lack of shine.
 
To prepare your hair for the perm, deep conditioning treatments are essential. Ideally, you should focus on intensive conditioning for at least a week before your perm. This helps restore moisture and strength, ensuring your hair is in the best possible condition. However, right before the perm service, you’ll need to shampoo your hair without conditioner - using a clarifying shampoo is even better - to remove any product buildup that might interfere with the perm’s effectiveness.
 
If you’re unsure about your hair’s condition or want to confirm that the perm formula you’ve chosen will work well, I highly recommend doing a test curl. Here’s how:
 
• Select a small, discreet section of hair (preferably near the nape or behind the ear).
 
• Wrap it around a perm rod as you would for a full perm.
 
• Apply the waving lotion and process it for the recommended time.
 
• Rinse thoroughly, apply the neutralizer, and rinse again.
 
After the test, carefully examine the curl’s texture and the hair’s integrity. Does it feel overly dry or brittle? Does the curl hold well? This test will help you determine whether you need to adjust the processing time or choose a gentler formula before perming your entire head.
 
Taking these precautions will help ensure beautiful curls while minimizing the risk of damage.
