"Thermal Straightening" or "Japanese Straightening" treatments offer an incredible remedy for severely curly and frizzy hair. However, most treatments can use chemicals that are harsh on the hair and unsafe for the user.

Other treatments that are gentler do not produce drastic or permanent results. Rusk Thermal Str8 gives the professional stylists a fabulous option for permanently straightening and smoothing even the most stubborn curls without harsh or unsafe chemicals.

Rusk Thermal Str8 is formeldahyde free, so it is extremely safe for all hair types, yet potent enough to turn kinky, unruly hair into shiny and frizz-free in one salon visit. Thermal Str8 uses a keratin-based formula with Vitamin B and natural proteins, driven into the hair with the heat of a Rusk Professional Str8 flat iron to straighten hair with a two part process.

Step 1 is called Internal Retexturizing Cream and is brushed through the hair and left on to process. The hair is rinsed and dried and then ironed straight. Step 2 is called Internal Reconstruction Lotion and is applied to the dried and straightened hair and left to process for just 5 to 7 minutes. The hair is then rinsed, dried, and flat ironed again. There is one treatment for normal or color-treated hair and a separate treatment for virgin hair or resistant/coarse hair. The treatment is completely permanent so hair stays straight, however, the treatment needs to be repeated on re-growth about every 16 weeks to avoid a line of demarcation.

The keratin, vitamins, and proteins are pressed into the hair with the hot flat iron, delivering the smoothing, shine-enhancing benefits. Those with hard-to-manage and excessively curly or kinky hair will find this treatment life-changing as it cuts their blow-dry and styling time down to a fraction of what they are used to. Over time the hair will look and feel healthier because the need for heat styling will be reduced.

Stylists trust Rusk for their thorough research and formula design that creates novel products which address unmet needs within the industry. For stylists who seek a way to provide their clients with incredibly straight hair without the use of damaging chemicals, Rusk Thermal Str8 offers the perfect solution.
