Expert strand-by-strand keratin bond and tape-in extension fittings by certified sisters Mădălina & Cornelia. Master craftsmanship, zero damage, and natural movement.
The secret to long-lasting, invisible hair extensions lies entirely in the precision of the fitting. Incorrect sectioning or uneven weight distribution causes traction stress, bond slippage, and damage to your natural follicles.
At Sisters Hair Extensions, founders Mădălina and Cornelia personally perform every fitting. With over 8 years of specialist experience, we apply a strict 1:1 weight-calibration protocol: the weight of each extension strand exactly matches the density of your natural root hairs.
Whether you want to add dramatic length, double your ponytail thickness, or recover from heat damage, our fittings are completely pain-free, comfortable, and tailored to your lifestyle.
We focus exclusively on the two healthiest, most discreet methods in the industry:
Individual strands tipped with high-grade Italian keratin are fused to micro-sections of natural hair using a controlled acoustic heat tool. The cooled bond forms a tiny, flexible rice-grain seal.
Pre-taped 4cm panels are applied by sandwiching a thin slice of your natural hair between two medical-grade hypoallergenic adhesive tabs. Sits 100% flush against the scalp.
15–20 minutes to evaluate your natural hair, assess density, select length, and match your custom colour blend.
We section your hair with millimetre precision, leaving a 1.5-inch safety perimeter around your hairline and crown.
Strand-by-strand or panel fitting with balanced root tension so attachments feel completely weightless.
Custom point-cutting and heat styling to ensure the transition between your natural hair and extensions is 100% invisible.
Every quote is all-inclusive: 100% premium human hair, artisan fitting, blending cut, written aftercare guide, and follow-up support.

A professional fitting includes precise scalp sectioning, weight-calibrated strand attachment (matching extension weight 1:1 to natural hair density), blending cut, and custom styling. We exclusively fit premium keratin fusion bonds and ultra-flat tape-ins.
Keratin bond fittings typically take 3 to 5 hours due to meticulous strand-by-strand placement. Tape-in fittings are significantly faster, taking approximately 60 to 90 minutes for a full head.
