This step-by-step guide will walk you through both processes.
Part 1: How to Apply Hot Fusion Extensions (Keratin Bond Method)
What You’ll Need:
Hot fusion keratin bonds Specialized heat clamp Sectioning clips Fine-tooth comb Heat protectant spray
Step-by-Step Application:
1. Prep Your Hair
Wash and dry your hair thoroughly (no conditioner or oils).
Lightly tease the roots where bonds will be placed for better grip.
2. .Section Your Hair
Divide hair into small, even sections (about ¼ inch wide).
Clip away the rest to keep it organized
- Attach the Bonds
Take a small strand of natural hair and thread it through the keratin bond.
Use the heat clamp to melt the bond, sealing it securely.
Hold for a few seconds until the bond hardens.
- Repeat & Blend
Work from the nape up, placing bonds in a staggered pattern.
Once all extensions are in, style as desired.
Pro Tip:
Avoid placing bonds too close to the scalp (about 1 cm away is ideal).
Use heat protectant if styling with hot tools near bonds.
Part 2: How to Remove Hot Fusion Extensions
What You’ll Need:
Bond remover solution Fine-tooth comb Clips Deep conditioner
Step-by-Step Removal:
- Apply Bond Remover
Spray or apply keratin bond dissolver directly onto each bond.
Wait 5-10 minutes for bonds to soften.
- Gently Slide Off
Use your fingers or a tail comb to gently roll the bond off the hair.
Never pull—this can cause breakage!
- Wash & Condition
Shampoo to remove residue, then use a repairing mask.
Let hair rest before reapplying extensions.
