Shipping & Delivery

Where do you ship? We ship worldwide. K-Revive Serum is designed in Ireland and shipped from our overseas fulfilment partner.

How much does shipping cost? Standard shipping is free on every order, worldwide, and includes live tracking. Express shipping is available at the rate shown at checkout. The price you see at checkout is the price you pay, with no hidden handling fees.

How quickly will my order ship? We process orders within 2 to 3 business days. Orders placed before 3:00pm GMT+1, Monday to Friday, begin processing the same business day. Orders placed after the cutoff or on weekends and holidays begin processing the next business day.

How long will delivery take? Standard shipping takes 5 to 8 business days in transit, and express takes 4 to 6. Including processing, most standard orders arrive within about 7 to 11 business days of being placed, and most express orders within about 6 to 9.

Will I get tracking? Yes. Live tracking is included on every order, standard and express. As soon as your order ships you will receive a confirmation email with your tracking link. Please allow up to 24 hours for tracking to update after the label has been created, and note that tracking can pause for a day or two while your parcel moves between carriers.

What if I entered the wrong address? Email us at mail@nz-ecommerce.com as soon as possible. We can only correct an address before the order ships.

My tracking says delivered but I don't have it. What now? First contact the delivering carrier using your tracking number, as they can often locate recently delivered packages. If you still need help, email mail@nz-ecommerce.com and we will do our best to assist.

Returns, Refunds & Our Guarantee

What is your guarantee? Every order is backed by our 30-Day Money-Back Guarantee. If you are not satisfied for any reason, you can request a refund within 30 days of your order being marked as delivered.

Do I have to mail the serum back? No. Because this is a personal care product applied directly to the scalp, we cannot accept physical returns for health and hygiene reasons, and you never pay return shipping. Just request your refund by email.

How do I request a refund? Email mail@nz-ecommerce.com within 30 days of delivery with your full name, order number, and the email address used at checkout. Email is our official channel for refund requests.

How long do refunds take? We review requests within 2 to 3 business days. Once approved, your refund is issued to your original payment method within 2 business days, and your bank typically posts it within 5 to 10 business days.

What if my order arrives damaged or incorrect? Email mail@nz-ecommerce.com within 7 days of delivery with your order number and a photo of the issue. We will send a replacement or issue a full refund at no cost to you.

The Product

What is K-Revive Serum? A lightweight, water-based scalp serum with a soft silicone brush built into the tube. It is Korean-style scalp care: the formula is made for the skin your hair grows from, not for the lengths.

What does the brush do? The bristles part your hair so the serum lands on your scalp instead of soaking into your strands, and the gentle pressure massages your roots while you apply it. With a dropper, much of the product ends up on your hair rather than where it is needed.

What is in it? Caffeine and biotin to support the roots, niacinamide and Korean Heartleaf extract to calm and balance the scalp, panthenol and glycerin for moisture, and green tea and turmeric extracts as antioxidants. Full ingredient list: Aqua, Glycerin, Dipropylene Glycol, Caffeine, Niacinamide, Panthenol, Hydroxyacetophenone, Xanthan Gum, Polyquaternium-51, Betaine, Menthol, Polygonum Cuspidatum Extract, Camellia Sinensis Leaf Extract, Curcuma Longa Root Extract, Glycyrrhetinic Acid, Bisabolol, Biotin, Disodium EDTA, Heartleaf Extract.

Does it contain Minoxidil? No. There is no Minoxidil and no pharmaceutical active of any kind in K-Revive.

How do I use it? Once a day. Place the bristles on your part line, squeeze and glide along the part, massage in small circles, and style as normal. It takes about 60 seconds.

Will it make my hair greasy? No. The formula is water-based with no oils, and it absorbs in under a minute, so you can apply it and style right away.

When will I notice a difference? Hair grows slowly. With daily use, look for less shedding on wash day in the first few weeks, baby hairs along your part around weeks 4 to 8, and a fuller-looking part after about 2 to 3 months. Everyone is different, which is why consistency matters more than anything else.

How long does one serum last? One 100 ml serum lasts about a month with daily use, depending on how much you apply and how large an area you are treating.

Does it work for my hair type? Yes. It is applied to the scalp rather than the hair, so it suits straight, wavy, curly and coily hair, and it is safe for colour-treated hair.

Can I use it if I am pregnant or breastfeeding? Please check with your doctor first. We cannot give medical advice about use during pregnancy or breastfeeding.

Is it safe around pets? There is no Minoxidil in K-Revive, which is the ingredient commonly associated with toxicity in cats and dogs. As with any skincare product, let it absorb before close contact and keep the tube out of reach.

Is it safe to use? K-Revive is a cosmetic scalp care product for external use only. Avoid contact with the eyes. If you have a scalp condition, are under treatment, or notice irritation, stop using it and speak to a healthcare professional.

Do I have to keep using it forever? No. There is no drug in it for your scalp to become dependent on. Daily use gives the best results, but you can stop at any time.

Orders & Payment

Is this a subscription? No. Every order is a one-time purchase. There is no membership and no recurring charge, and you will never be billed again unless you place a new order yourself.

What payment methods do you accept? We accept all major payment methods, including Visa, Mastercard, American Express, Apple Pay, Google Pay, Klarna, PayPal, and Shop Pay.

Can I change or cancel my order? Contact us at mail@nz-ecommerce.com as quickly as possible. We can only change or cancel an order before it has been processed for shipment.
