"For Koils" Wefted Hair


Get secure coverage with the most natural protection for your full or partial sew-in with our 100% virgin wefted hair extensions.

In our signature “For Koils” texture, springy ringlet curls are densely packed together in an elongated s-pattern. Strands offer medium coarseness and retain curls well with a medium to high luster.

Experience a look true to you, beautifully made to blend with your 3B-3C natural hair. Our high-quality “For Koils” wefted hair may be used to add versatility, fullness, and length, whether you choose to leave part of your natural hair out, or fully protect it underneath one of our seamless closures.

Each wefted hair bundle is offered in its unaltered natural color, weighing approximately 4 ounces (113.4 grams). To achieve a full look with lengths 18 to 24 inches, we recommend that you purchase 3 bundles for optimal coverage and volume.

Frequently asked questions

  • Quarterly Collections are hand-made just for you to ensure only the best quality! All Quarterly purchases will ship between 01/4/2021 and 01/8/2021.

    Once your order ships, you will receive an email with your tracking information. Your delivery estimate will be calculated from the date your order is shipped, not the date it is placed. Shipping estimates are applicable to business days only and do not include weekends and/or holidays. All packages require a signature for delivery. 

  • To find the perfect capsize you'll need is a fabric measuring tape. You'll be measuring the perimeter of your head, following your hairline as a guide. Place one end of the tape at the nape of your head and go all the way around until the two pieces of the tape meet. The number that you get will coincide with one of the capsizes. If you are between capsizes, we recommend sizing up. 

    Small- 18"-20" 

    Medium- 20" to 22" 

    Large- 22" to 24"

  • Coloring*

    Heat Free Hair extensions are offered in their natural unaltered color state with variations of dark brown and black hues. At this time, we do not offer additional color options or custom coloring services. To make Heat Free Hair extensions fit your desired look, our hair may be bleached or dyed to any color to blend with your natural hair. We recommend coloring extensions prior to installation. Just like natural hair, bleaching or using color with harsh chemicals may weaken the hair shaft and potentially alter the texture. Heat Free Hair extensions that have been colored require extra love and attention throughout the life of your look. Please be sure to deep condition extensions and use nourishing hair products whenever possible.

    *We recommend that coloring be done by a professional, licensed colorist familiar with natural textures. Heat Free Hair curl patterns are steam processed to create each unique curl pattern. Lifting the hair with high volumes of developer to extremely light colors may alter the integrity of the texture and curl pattern. Heat Free Hair is not responsible for any damage of hair quality or texture as a result of color processing.

     Heat Styling & Straightening

    Just like natural hair, Heat Free Hair has beautiful styling versatility. You may wear our looks as they come, or use heat styling tools to achieve your desired look. Keep in mind that our virgin hair is just as susceptible to heat damage and loss of curl pattern as your own natural hair is. Use a heat protectant when necessary and avoid excessive exposure to straightening tools.

  • Our Headband wigs are great for a full protective style, with minimal leave-out required. Since the wigs provide close to full coverage with the exception of your hairline, you can choose the texture you most desire. You can also use True You, our product finder tool, to help you make the best product selection.

The hair was super soft and bouncy even after coloring it. Easy to upkeep and to blend into my natural hair! I would definitely recommend getting the clip ins too!

Wonderful and Excellent!!!

My overall experience with Heat Free is wonderful. The quality of the hair is excellent, the delivery time is excellent, the customer service is excellent. My only minor complaint is the website experience. It can use some tending to as it can be very slow at times, however the hair, customer service overshadows the downside.
