F.A.Q. - Real Extensions Buying Guide
Common questions and answers about hair extensions and Original Diva.
Are your extensions made from real human hair?
Original Diva’s hair-extension range is made from 100% human, silicone-free hair. Hair accessories and application tools are separate products.
What types of hair extensions are available?
- Clip-In Extensions: removable extensions you can apply and take out at home.
- Tape Extensions: professionally fitted hair attached with flat adhesive tabs.
- Micro Ring / I-Tip Extensions: individual strands fitted with small bead attachments, without heat or glue.
- Weft Extensions: continuous rows of hair fitted using a professional row-based method.
Can hair extensions damage natural hair?
No extension method is completely risk-free. Appropriate hair weight, placement, maintenance and careful removal help reduce unnecessary stress on natural hair. Permanent methods should be professionally assessed, especially for fine, fragile or actively shedding hair.
Can I style human-hair extensions?
Human-hair extensions can generally be curled, straightened and styled with appropriate heat protection and care. Follow the instructions for your extension type and avoid unnecessary high heat or chemical processing.
Can I swim with hair extensions?
Clip-in extensions should be removed before swimming. With professionally fitted permanent extensions, rinse the hair with fresh water after swimming, detangle gently and follow the aftercare guidance for your method. Chlorine and saltwater can increase dryness and tangling.
How do I choose the right extension method?
Choose based on your natural hair density and condition, the length or volume you want, how often you want to wear extensions and how much maintenance suits your lifestyle. Nicole can help you compare removable clip-ins with professionally fitted tape, micro ring / I-Tip and weft methods.
How should I care for hair extensions?
Care depends on the extension method. Use suitable products, detangle gently, protect the hair from unnecessary heat and follow the maintenance schedule for professionally fitted methods.
How do I purchase hair extensions online from Original Diva?
Browse the online range, choose your product options and complete your order through secure checkout. Original Diva ships Australia-wide, with free standard shipping on Australian orders of $150 or more.
Can I match the extensions to my current hair colour?
Yes. Use our free colour-matching service to send clear natural-light photos and Nicole can recommend the closest suitable Original Diva shade or blend before you order.
Do you offer professional application services?
Yes. Nicole personally handles Original Diva salon appointments at the private Hunters Hill studio for consultations, colour matching, professional installation, cutting, blending and maintenance.
