Thermal color change hair is made from polypropylene fiber that changes color in reaction to changes in temperature.
Thermal hair has a higher resistance to heat than kanekalon, but can still be sealed with a steamer and will melt under high, dry heat like a straightener/flat iron. Boiling water generally is not hot enough to seal it. It will not shrink when sealed, but will hold its shape once set.
If the ambient temperature of the room you're in is close to the point where the color changes, sometimes it will appear to get "stuck." You can get it to go back to the other color by exposing it to heat or cold (depending on what color it is and what you want to change to).
Thermal Hair cannot "burn out" - the fiber will never stop being able to change colors.
Length: 19" (48 cm) folded, 38" (96 cm) unfolded.
Weight: 0.78-0.88 oz (22-25 g). Thermal hair comes in small packs that contain enough for a few braids, or for highlights/accents.
Texture: Straight. The strands are very fine and prone to tangling, so it's important to be careful and gentle when separating it. We do not recommend wearing thermal hair loose.
Color: Dark Amethyst/Orchid Purple.
For Dark Amethyst/Orchid Purple, the "warm" color is Orchid Purple and the "cool" color is Dark Amethyst. If it's stuck on Orchid Purple, expose to something cold (like ice) to change it. If it's stuck on Dark Amethyst, apply heat to change it.
Dark Amethyst/Orchid Purple is Orchid Purple at room temperature (around 70 °F).
