1. What’s the difference between Hot Fusion and Cold Fusion?
- Hot Fusion: Uses heat-activated keratin bonds for a strong, long-lasting hold (3-5 months).
- Cold Fusion: Uses ultrasonic waves to attach polymer bonds—no heat, gentler on hair (2-4 months).
2. Which lasts longer?
Hot Fusion typically lasts slightly longer (3-5 months vs. 2-4 months for Cold Fusion).
3. Is one safer for thin/damaged hair?
✅ Cold Fusion is better for fragile hair—no heat means less damage.
4. Can I style/extensions with heat tools?
- Hot Fusion: Yes, but avoid direct heat on bonds.
- Cold Fusion: Use low heat and protect bonds.
5. How are they removed?
Hot Fusion: Requires a bond dissolver (professional removal recommended).
Cold Fusion: Bonds slide off easily with alcohol or remover spray.
6. Which looks more natural?
Both blend seamlessly, but Cold Fusion bonds are lighter and may feel more natural.
7. Can I reuse them?
No—fusion extensions are single-use, but the hair can be reused with new bonds.
8. Which is more expensive?
Cold Fusion costs slightly more due to specialized tools.
