Section 1: Pre-Installation & Hair Suitability
Are Pre-Bonded Extensions Safe for Thin Hair?
Yes, they are highly safe. Our Flat-Tip bonds are designed to lay flush against the scalp, distributing weight evenly to prevent tension. When applied by a professional, they remain discreet and won’t damage fine strands.
How Many Packs Do I Need for a Full Head Transformation?
For a complete transformation with significant length and volume, we recommend 3-4 packs (150g-200g). If you are only looking to add subtle thickness to your natural length, 1-2 packs (50g-100g) are typically sufficient.
U-Tips vs. Flat-Tips: Which Bond Type is Best for You?
U-Tips allow for 360° natural movement, making them ideal for thicker hair. However, Flat-Tips are much flatter and more undetectable, providing the perfect solution for those with thinner hair or sensitive scalps.
Section 2: Performance & Longevity Standards
How Long Do Full Shine Italian Keratin Bonds Last?
Full Shine extensions utilize premium Italian Keratin, which lasts between 3-5 months with proper maintenance. To protect your natural hair roots, we suggest a professional re-fitting session every 6-8 weeks as your hair grows.
Why Do My Extensions Feel Loose After Installation?
Slippage or looseness is usually caused by applying oil-based products too close to the roots or insufficient heat during the fusion process. Always keep conditioners away from the bonds to maintain a strong, secure seal.
Can the Bonds Be Reused After Removal?
Absolutely. While the original bond is removed, the high-quality hair can be reused. Simply have your stylist re-tip the strands using our professional Italian Keratin grains to restore the extensions for a second or third installation.
Section 3: Professional Styling & Chemical Guidelines
Can I Dye or Bleach Pre-Bonded Hair Extensions?
You can safely dye the hair to a darker shade, but we strongly advise against bleaching or lifting the color. Harsh chemicals can degrade the cuticle and weaken the keratin bond’s structural integrity over time.
What Temperature is Safe for Styling Keratin Bonds?
We recommend keeping heat tools below 180°C. It is critical to never apply a flat iron directly to the keratin bonds, as the high heat will re-melt the adhesive, leading to immediate slippage and potential tangling.
Best Shampoos to Prevent Bond Slippage.
Use only 100% sulfate-free and silicone-free shampoos. Traditional formulas containing heavy oils or silicones can lubricate the bond area, causing the keratin to soften and eventually slide down the hair shaft prematurely.
