Yes, our full cuticle Remy quality hair can tolerate heat-styling tools up to high temperatures. This includes our textured extensions. For example: styling tools that reach a setting of 480°F can be necessary for individuals with natural 4a to 4c hair types, which often have a coarser texture. The elevated temperature allows for effective straightening or styling, helping to achieve the desired results more efficiently on thicker and coarser hair. Using a heat protectant spray before applying heat to your MANESTORY extensions and your natural hair is essential. Excessive heat styling has the potential to reduce the lifespan of your extensions. So, we recommend exercising caution and using these tools sparingly.
