Is your fine, soft hair constantly falling out with Hot Fusion Extensions? Even though keratin has strong adhesion, it keeps coming undone because the hair strands are too slippery or the heating method isn’t right? Don’t let “soft hair” waste this great product! This article is tailor-made for you, with 3 core techniques to ensure keratin firmly “wraps” your fine, soft hair, keeping it stable for 6-8 weeks without falling out.
I. Pre-installation: Fine hair “pre-treatment”
Cleansing: Removes oil and frizz.
2.Installation in progress: Keratin heating with “3 precisions”
Temperature control: 160-180℃, no perming, no stickiness, no hair loss.
Heating time: 10 seconds. “Stage-wise” heating allows keratin to tightly coat the hair strands.
Fitting Technique: Use a “small angle” to clamp the hair, reducing root pulling.
3.Three things you “cannot” do
Do not use styling products containing alcohol (such as hairspray or setting spray) or spray glue particles (as this will make keratin brittle and prone to falling off).
Do not wash your hair frequently (frequent washing will cause the adhesive particles to become damp and reduce their stickiness).
Do not pick at the adhesive beads with your hands (even if they are loose, do not pick at them to avoid pulling out your own hair).
