A: We sell a full range of 100% human hair extensions from Echo, including Russian Remy weft, Virgin Remy, Pure Brazilian, European weft, nano tip, tape in and clip in hair extensions. All are available in a wide range of shades from 12 to 26 inches. Use our free Hair Extension Match Finder to find your perfect match.

A: Nano tip extensions use tiny keratin bonds attached strand by strand, making them virtually invisible and ideal for fine hair. They typically last 3–5 months. Tape in extensions use adhesive wefts that sandwich sections of natural hair for a flatter, faster application and need repositioning every 6–8 weeks. Both methods use 100% real human hair and can be curled, straightened and washed like natural hair.

A: The best starting point for most people is Olaplex No.3 Hair Perfector used weekly as a pre-shampoo treatment, with No.4 shampoo and No.5 conditioner for every wash. If your hair is severely bleached or damaged, add No.0 before your No.3 treatment. For styling, No.6 Bond Smoother controls frizz and No.7 Bonding Oil adds shine and heat protection. Read our complete Olaplex guide for a full breakdown of every product.

A: Yes. As official authorised ghd stockists, every ghd tool we sell is 100% genuine and comes with the full UK manufacturer warranty. Buying ghd from unauthorised sellers risks receiving a counterfeit product that won't deliver results and won't be covered by warranty. Counterfeit ghd tools have also been found to reach damaging temperatures far above ghd's recommended 185°C.

A: Yes — many of our customers combine all three brands as part of their routine. A popular professional combination is using the K18 Molecular Repair Mask for rapid structural repair, maintaining with Olaplex No.4 and No.5 every wash, and using a Kérastase treatment mask weekly for nourishment and shine. There are no ingredient conflicts between the three brands.
