The Japanese straightening procedure called thermal reconditioning has increased in popularity. It is seen as highly effective, long-lasting, and promising in the search for pin straight locks. It is also known for being used on a wide variety of hair types. There are certain limitations, but it seems to worth well for most types. Certain hair types respond better than others. For example, it is still often not a recommendation for African hair types.
With tightly curled hair types the problems lies for regrowth. Thermally reconditioned curly hair may look awkward as the roots begin to grow and abruptly exposes your natural curls. It will be necessary to maintain it through regularly scheduled touch up appointments, which involve application of a solution that will soften the new growth of hair. A properly trained specialist will know the proper amount to apply to these roots, so they match your existing hair.
If your hair is bleached or has light highlights there are some risks involved with thermal recondition. Your salon should use a small test strand to see how your hair reacts to the solution. Your colored hair may or may not be able to withstand thermal reconditioning. Coarse, thick hair may react better with thermal reconditioning as opposed to fine hair. Adding more chemicals to hair that is already slightly altered may give you less than desirable results.
Allow your stylist to know your full color history, so he or she can make an accurate decision. He or she may ask you when the last color was placed in your hair and type of chemical that was used. Always answer these questions honestly, so you can avoid disappointment or damage to your hair. Avoid hair coloring within two weeks of your thermal reconditioning. Your hair needs time in between chemicals, let it take care of this naturally and give it enough time. Thermal reconditioning may change the shade of your color slightly, so be prepared for this. Shampoos are now available to help keep your hair color, so be sure to check these products out.
If you have recently relaxed your hair, then you must take extreme caution! Even if your hair relaxing was not successful, this is irrelevant. You must make your thermal reconditioning technician aware as to whether the relaxer you used was hydroxide or thio base. Thermal reconditioning itself is thio based, which makes it compatible with any other relaxers that are thio based. On the other hand, if the relaxer was hydroxide based, thermal reconditioning is not compatible! If you are unsure of the type of relaxer, make sure you have this information before attempting a thermal reconditioning.
