Care

How often should I wash my wigs or extensions?
Since you don’t sleep, sweat profusely, or excrete natural scalp oils on your Koils, they really don’t need to be washed that often. We recommend only washing them every 15-20 wears, or when there’s too much product buildup and they are becoming unruly to style. Each time you wash your Koils, some shedding/volume loss is inevitable in the detangling process, so the less that you wash them, the longer they will last.
How do I wash my wigs or extensions?
Easy! Fill your bathroom sink with warm water and a bit of your favorite shampoo. Submerge the hair and let it marinate for a few minutes before rinsing with warm water and draining the sink. Then, slather on a generous amount of conditioner and detangle the hair with a wide tooth comb or tangle teezer (gently! or it’ll break off just like your real hair would!) from ends to root. It’s easiest to work with extensions one weft at a time, and to detangle wigs in sections. (Pro tip: after detangling a section, loosely twist it up to get it out of the way.) Finally, rinse your Koils in cold water to seal the cuticle, and leave on a towel to air-dry.
What products should I use on Koil hair?
Koil sells only 100% virgin human hair, so use the same high quality products that you would put on your own hair. Remember, you don’t need to wash, condition, or style your Koils often, so a little bit of the good stuff goes a long way. Think Pureology or Oribe.

Styling

Can I straighten Koil hair?
Yes, but why would you want to? Just like our own hair, your Koils are susceptible to heat damage and loss of coil pattern (the horror!), so use a protectant spray and proceed at your own risk.

...seriously though? Put down the flat iron. Straight hair doesn’t do you justice. :)
Can I dye my wigs or extensions?
Sure you can! Since Koil hair is 100% virgin remy human hair, it can be dyed a darker color or toned by a professional hair colorist. We wouldn’t recommend bleaching though, as it’s a harmful chemical process that damages the integrity of the hair, leaving it more prone to dryness and tangling.
How do I blend my real coils with my Koil extensions?
After years of trial and error, we’ve come up with a foolproof way to make sure your real hair matches your extensions impeccably each time. Just wash, condition and then blow dry your hair into a fluffy afro state! Use a dryer with a comb attachment and a good blow out creme/spray (we recommend Oribe’s Royal Blowout spray; it is miracle potion, you will never see your hair so soft and shiny!) and once you’re done drying, seal the hair with an anti-humectant spray so it doesn’t shrink and tangle a crazy amount. (Oribe’s anti-humectant spray stands up to the Florida humidity for days! ...We promise we aren’t getting paid by Oribe—we just know a good product when we see one.) DO NOT put any oils and butters and other condiments in your hair after this; buildup is a hair-ruiner.

Now, take a boar bristle brush (Mason Pearson is where it’s at) and brush the coils out of your extensions until they’re good and fluffy and match your hair. When adding things like wand curls, start them a few inches down the hair shaft so that the top part is still in a fuzzy, undefined state just like your real hair. If your hair is more kinky, leave sections of your extensions on a very hot curling wand (without heat protectant) for as short a time as possible (just 2-3 seconds after wrapping), so the afro texture stays intact. If your hair is a bit straighter or silkier, spray ample heat protectant and leave your Koils on the wand longer (~20 seconds) so they smooth out a bit. Seal with a good hair spray, then clip in your clip-ins and go!

You won’t even be able to tell you have extensions in—much more to anyone else! Our models have a wide variety of hair textures and coil patterns, and Koil hair blends gorgeously on all of them. Our little technique works like a charm.

(P.S. Make sure to twist up your own hair before bed to minimize tangles overnight. If you used the right products, your hair will stay soft, lightly stretched and super manageable for about a week until you start over with a fresh wash.)
How long do clip-in extensions take to put in?
No more than five minutes once you get the hang of it!
How do I attach clip-in extensions?
Clip-in hair extensions attach securely under layers of your hair with small snap clips that are sewn tightly on to each weft. Once you snap them in, they’re not going anywhere! And best of all, you can’t see or feel them.
What’s an easy, go-to style I can wear with this hair?
We like to throw some wild wand curls in the hair, seal with a good hairspray and wear them for up to a month before re-styling! As the curls become more fuzzed out and undefined, they take on a life of their own. You’ll look effortlessly cool—and, for once, have actually expended very little effort to do so. Five minutes’ worth, to be exact.

Another favorite of ours is the giant afro. Use a blowdryer with a comb attachment to stretch out the Classic into a big mane. Then pat it into a round shape. Iconic, every time. Extra points if you leave a pik in it for the whole day.
I’m having trouble styling my Koils. Can you help?
Sure! Email hello@koil.co with your struggles. We’re happy to send you tips!

General Qs

How many sets of extensions do i need?
Depends. If you’re adding clips to your real hair for extra volume, you may only need one set. For extra length and a full head, two sets will do the trick. Note: That goes for fluffy styles like wand curls, brushed out afros, etc. If you love to do styles that compress the hair (like defined twist-outs) you may need 3 sets to get desired fullness.
Does Koil hair shed and tangle?
Yes, of course! Just like the hair on your head. You can minimize shedding and fallout by not yanking violently when detangling, brushing, styling or washing. Be patient and gentle, and when in doubt deep condition the hair for 3-4hrs or overnight, to soften it beforehand.
How long do Koil wigs and extensions last?
The lifespan of your Koils is determined by how well you care for them, what products you use on them, and how often you wear them. Usually, they last 3-6 months to a year or longer. This also depends on your styling choices: if, for example, you purposefully encourage the hair to dread up (this looks really cool, tutorial soon!), it can last infinitely in that state, but the detangling process (shedding, meet tangles) would be your hair’s demise.
Can I go swimming in my extensions or wigs?
Please don’t. You’d rather not deal with the tangle nightmare that will result—trust us. Sure, you can wear Koil hair to the beach and spend the whole time burning up in the sand, avoiding the sea to preserve your precious ‘do. But we’re the type who like to splash fight and snorkel. Just throw some cute cornrows in and enjoy the water for a change, alright? :)
Why should I shell out for human hair when synthetic hair is so much cheaper?
Hair extensions and wigs made from human hair can be dyed, washed, blow dried, twisted-out and wanded just like your real hair. They blend effortlessly, last long (up to a year!) and leave you with infinite styling options. Synthetic hair is processed with numerous harmful chemicals that can cause skin irritation. It lacks the softness and authentic texture of human hair. It typically can’t be styled with hot tools and—how can we forget!—looks terrible after just a few  weeks days’ wear. Unless you’re installing braids, synthetic hair is a no from us.
Why is 100% Virgin remy hair the superior choice for hair extensions and wigs?
100% virgin remy hair is considered the finest quality of human hair available on the market today, because the cuticles are kept intact, and not stripped like in most other non-remy hair extensions.

Preserving the hair cuticles and aligning them in an unidirectional fashion creates extensions and wigs that are completely natural looking. This process ensures that the hair remains super soft and manageable throughout its lifetime.

Shipping & Delivery

Free expedited shipping. Worldwide. (No Lie)

Oops! Can you cancel or change the address of my order?
We ship packages super fast (practically right after you order!) so it’s on you to make sure your info is correct. If you email us at hello@koil.co soon after you checkout, we may be able to help--but we can’t make any promises.
Do you ship internationally?
Yes! We offer FREE expedited international shipping on all orders.
Do I have to pay customs or import duties?
If you live outside of the U.S., you may be charged annoying fees like customs, duties, VAT, etc, once your order arrives. Your local carrier or government collects these—not us!—so they’re not included in our pricing and are excluded from any refunds. Contact your country's customs office or tax agent to learn what fees you can expect.

Oh, also: To ensure the DHL courier can deliver your package in the shortest possible time after entering your country or customs union, DHL pays customs on your behalf for any duties and taxes that are due on the goods. Once the duties and taxes are fully repaid to DHL, your package will be delivered to you. Or sometimes you’ll get an invoice from DHL after your package is delivered, for the charges they’ve paid on your behalf at destination, plus a small administration fee.
What’s this extra International Transaction Fee ($3-5)?
Koil is based in the U.S. If you don’t live here, your bank or credit card company might charge you an extra $3-5 fee for placing an order outside of your home country. We think this is extremely petty but sadly can’t do anything about it. And because it’s not us getting the money (even if it seems so on your card statement) we can’t refund it either. Contact your bank with any questions about this nonsense fee.
How long will my order take to arrive?
We ship all orders within 1 full business day. We ship Monday-Friday, except on holidays. You’ll get a tracking number once your order ships. Estimated arrival is 2-3 business days for U.S. customers, and 2-5 business days for international.

On very rare occasions, international shipping can take 4-8 weeks or even longer for some slow-to-ship countries such as Australia, Brazil, Mexico, and Romania. We’re not responsible for any delays caused by the destination country's customs clearance processes.
How do I track my order?
You’ll get a confirmation e-mail once your order has been processed to the e-mail address provided at the time of checkout. A second e-mail will let you know that your order has shipped, and include your tracking number. If there is a problem with your tracking number or package delivery, please contact the courier directly prior to contacting us. Please allow 24 hours for the tracking information to show. In some rare case, the tracking information may not update but you will still receive your order. Please contact us after the estimated delivery time.
What does it mean when an item is on back order?
This means that we’ve sold out of an item and are waiting for the new shipment. If you buy something on back-order, we’ll ship it to you as soon as new inventory arrives. It’ll be worth the wait, we promise!

Returns

Do you accept returns?
Yep! If you’re not obsessed with your Koils by day 30 (which, we will warn you, is impossible), just email hello@koil.co with the subject line “RETURN REQUEST”, your order number, and what items you would like to send back, and wait for instructions. We’ll take them back for a full refund, no questions asked.
What is the return period?
Within 30 days of the delivery date.
Do I have to pay for return shipping?

Do I have to return the original packaging?
Yes, hair must arrive in its original packaging (box, satin bag, etc.) or your return will not be accepted.

After we’ve received your return and confirmed that the hair and packaging is intact, we will send the refund. It may take up to 6 business days to see it reflected in your account.
Can I return an order without contacting you first?
No, you must contact us before sending your return, as the address may be different from the one your order was originally shipped from. We won’t refund items that were returned without notifying us beforehand.
