What makes SISIYUYU different?
SISIYUYU is built around ready-in-minutes hair confidence: believable fullness, shade help, and human-hair pieces that fit real daily routines without a salon appointment every time.
Is SISIYUYU hair real human hair?
Our core extension products are positioned around real human hair feel and movement. Always check the individual product page for the exact material, length, shade, and care notes before checkout.
Who is SISIYUYU best for?
SISIYUYU is best for customers who want fuller-looking ends, polished ponytails, or longer-wear fullness with less guesswork around method and shade.
Do I need professional help?
Halo and ponytail pieces are designed for simple on/off wear. Tape-in extensions are better handled with professional installation if you want a flatter longer-wear result.
Will it look obvious?
No, not when the method, shade, and placement are right. The goal is believable fullness that makes the style look finished, not a costume effect.
Which method should I start with?
Start with Halo for removable daily fullness, Ponytail for quick polished length, and Tape-In for flatter longer-wear fullness.
How fast can I wear it?
Halo and ponytail pieces are made for quick routines. Tape-ins take longer because they are intended for a more committed install.
Can I wear it every day?
Yes, if you choose the right method. Removable pieces should be taken off before sleep. Longer-wear methods need gentler ongoing care.
How do I pick the right shade?
Match the hair people actually see: your mid-lengths and ends in natural daylight. If you are between shades, choose the blend that best matches the ends near the extension.
What if I choose the wrong shade or method?
Contact support with your order email and clear daylight photos. We will help you understand the best next step based on the product and return condition.
Can I track my order?
Yes. Use the tracking link sent to your checkout email. If tracking has not updated yet, allow the carrier time to scan the package first.
Can I change my shipping address after ordering?
Contact us as soon as possible with your checkout email and order number. If the order has already moved into fulfillment, changes may not be possible.
How do I modify my order?
Email support quickly with your order number and the exact change needed. We can only modify an order before it enters fulfillment.
How do I cancel my order?
Send a cancellation request as soon as possible. If the package has already shipped, the return policy will apply instead.
When can I expect my order?
Processing begins after payment confirmation. Delivery timing depends on the shipping method and carrier route shown at checkout.
What is your return policy?
Return or exchange requests must be submitted within 30 days of delivery. Eligibility also depends on the product condition and whether the item has been worn, altered, or damaged. Review the return page before sending anything back.
How do I start a return or exchange?
Contact support with your order email, order number, and the reason for the request. We will confirm the next step before you ship anything.
Are shipping fees refundable?
Shipping fees and return shipping depend on the situation and the policy that applies to your order. Support will confirm before the return is processed.
When will I receive my refund?
After an approved return is received and inspected, the refund is processed back to the original payment method according to the payment provider timeline.
