1. How much hair will I need?

A full sew-in weave with our hair would require 3 bundles if lengths are 20 inches or shorter. For lengths of 22 inches and up, 4 bundles are required for a full head weave. With a closure, 3-4 can be used for a voluminous install however only 2-3 would be needed for a completed install. With a frontal, 3 bundles would be needed for a voluminous install however, 2 bundles can be used for a complete install (and from experience, 2 bundles + a frontal with our hair? Beautifully full.) Each bundle of our hair is 100g or more, with the weight being in between 3.3-3.8 ounces regardless of length. Keep in mind that since the hair is sold by total weight the rule is: “The longer the hair, the shorter the weft.”

Also, keep in mind two wefts of the same length may weigh the same, but may not have the same length of hair on the weft. Don’t fret, you won’t need more hair. This is totally normal and a result of some of the wefts being constructed thickly, which is occasional in production and will still give you a quality end result. Sew on!


2. What all can I do with this hair?

Because our hair is 100% chemically untouched, our virgin remy human hair is able to perform amazingly through color, bleaching, and heat styling. You can absolutely color treat and lighten our hair, however once Virgin Remy hair is treated in any way, it is no longer considered virgin. Be sure to keep color treated hair conditioned and moisturized with the recommended products on the hair care page, and if you are inexperienced or unsure of what to do in any way, please consult a licensed professional to protect your investment.


3. How long can this hair last?

Our hair can last for quite a long time, at least 2 years with proper care and maintenance. We want to make sure you’re prepared to have great hair for a long time, so we prepared a thorough hair care guide with recommended products to use with each texture we provide.


4. What do I need to use to keep the hair at its best?

We know it’s a new challenge figuring out what the best products are to use on your new extensions, so we created a thorough hair care guide to help you no matter what the texture is. We believe in keeping it simple and very reasonable. Check out our Hair Care Guide here!
