Frequently asked questions
What makes RealFeel™ extensions different?
Revyv’s exclusive RealFeel™ fibre is a premium synthetic material that looks and feels like human hair. Soft, silky, and naturally straight with a smooth finish that never feels fake.
Are these extensions human hair?
No – these are synthetic 18” clip-in extensions crafted from premium RealFeel™ fibre that looks and feels like real hair.
Are these extensions suitable for short hair?
Yes – these clip ins for short hair are ideal for adding length and volume to shorter cuts while blending seamlessly with your natural strands.
Can I use heat on these extensions?
Yes – our straight hair extensions are heat-resistant up to 180°C, so you can curl, wave, or restyle as desired.
Can I dye or tone the RealFeel™ extensions?
No – synthetic fibres don’t absorb dye in the same way as human hair. We don’t recommend colouring or toning your synthetic hair extensions, as it may damage the fibres.
Can I wash my RealFeel™ clip-in extensions?
Yes – gently wash with cool water and mild shampoo, then air dry flat to maintain the sleek, straight finish.
How long do RealFeel™ extensions last?
With proper care, your RealFeel™ 18" synthetic hair extensions can last up to 6+ months, depending on how often you wear them and how well you maintain them.
Do I only need one piece?
Yes – this is a 1-piece 18 inch clip-in extension that gives a full, voluminous finish on its own. It’s straight, silky and thick enough to give you a full, natural look with just one piece. If you feel like you need two, you can always buy another once you've checked the fit.
How do I blend straight extensions with short hair?
Section your hair, clip in your straight hair extensions near the crown, and lightly brush through with a soft bristle or detangling brush. You can also blend using a curler or blow-dryer on low heat to match your natural hair.
Can I use Revyv Hair Spritz or Hair Perfume on these?
Yes – the Revyv Hair Spritz is completely safe to use on RealFeel™ synthetic hair extensions. Unlike regular perfume, it’s made with castor and argan oils instead of harsh alcohols, so it won’t dry out or damage the fibres. It’s the perfect way to refresh your straight clip-in extensions and add a light, long-lasting scent between wears.
