Three bundles or four? If you are planning a sew-in or having a wig made, that is often the first decision. Three bundles are a useful starting point to discuss with your stylist, but the right amount depends on the weight of each bundle, your lengths and how full you want the finished style.
Before ordering, send your stylist a reference photo and the details of the set you are considering. It is easier to agree on the amount now than to discover you need another bundle during your appointment.
Start with the weight per bundle
Not every bundle contains the same amount of hair. Check the weight in the product description before comparing sets or prices.
For example, three 100-gram bundles add up to 300 grams of bundle hair. Four add up to 400 grams. That is a calculation example, so use the listed weight of your chosen product. A closure or frontal is counted separately.
Longer hair can need more fullness
When two bundles weigh the same, the longer strands spread that weight over more length. A set that works for a shorter style may not give you the same full look at a longer length, especially through the ends.
Texture changes the appearance, too. Curly hair can look fuller than straight hair, but that does not mean you should automatically order fewer bundles. Your stylist still needs enough hair for the planned track placement and coverage.
Choosing between three and four bundles

| If you want… | Check this before ordering |
|---|---|
| A shorter style with moderate fullness | Whether three bundles at the listed weight will cover your install. |
| Long lengths or a fuller finish | Whether a fourth bundle will help achieve your reference look. |
| A partial install | How much of your natural hair will be left out and how much coverage is needed. |
| A set with a lace piece | The closure or frontal size, as well as the bundle count. |
Your head size, parting and installation method all affect the plan. Extra hair should add the fullness you want without making the install uncomfortable. The American Academy of Dermatology recommends extensions that are light enough not to pull on your natural hair.
What is included in a 3+1 set?

A bundle-and-lace deal described as “3+1” usually means three bundles plus one closure or frontal. It does not mean four bundles, and the extra piece is not necessarily free. Check the selected listing for the lace type, size and hair length.
Choosing your bundle lengths
A 16/18/20-inch set gives your stylist three lengths to work with. It does not mean the whole style will be 20 inches long. If your reference photo has layers or a full, blunt outline, ask which combination will suit the cut.
Raw or Virgin quality is a separate choice from quantity. You can compare NMA’s Raw and Virgin options before deciding on your set.
