What makes the RUBY different from other hair extensions?

The RUBY, powered by patent pending StyleFlex® shapeable spine technology, instantly transforms your look within seconds by adding length, volume, texture and color to your hair for a seamless, glamorous look. The RUBY securely attaches on top of your hair with a unique fastening system, eliminating the disadvantages of traditional hair extensions to create multiple, versatile, stylish looks with salon quality hair at an affordable price in mere seconds. StyleFlex® saves you time and eliminates damage to your hair, without the use of unsightly clips, tape, beads or glue.

The RUBY is hand crafted and color blended using the highest quality Japanese and Korean fiber.

What if the color doesn’t match?

The RUBY comes in 28 different colors, so you can always find your perfect match! Our hair extension colors are multi-tonal, which means they should blend in naturally with your own hair when choosing a color in the same family. Go a shade lighter or darker as your natural hair varies from dark to light. Since our hair extensions were made for the top of your hair anything goes! Still not sure or need to exchange? You can always message or email us a few high-resolution photos of yourself showing your hair and we will do our best to help choose the right color for you.

Is the RUBY easy to apply?

The RUBY is completely do-it-yourself and can be applied in 30 seconds or less! You simply take the hair extension and secure through, directly over, or around the base of your pony or top knot and go! See our How-To Guide or our How-To Video section on our website for step by step instructions. Still having trouble? Call us at 1+877-587-7889 or email us at to schedule a 1 on 1 FaceTime or Zoom call with one of our experts for a live tutorial!

What if I don’t love my RUBY?

Return or exchange your RUBY for another item or a full refund, no questions asked, within 30 days! Call us at 1+877-587-7889 or email us at for assistance. We promise to offer you the best solution.
