How Do We Name the Hair Colors?

Generally speaking, the higher the color code, the lighter the color. For example, #22 is lighter than #18. #1 is the darkest and #60 is the lightest.

Gray Blends

For gray colors, the last two digits of the color code tell you the percentage of gray hair blended in. For example, in #210, the “2” is the darkest brown and the “10” means 10% gray hair. In the same way, #220 is that same darkest brown blended with 20% gray hair.

The Letter “R”

An “R” in a color code means the color is one shade lighter than the color before the “R”. For example, 4R means medium brown, one shade lighter.

NSY Hair Density Levels

Hair density standards vary among manufacturers, so our density levels may not match those of other vendors.

Hair system density refers to the amount of hair knotted (also called ventilated) onto the base. Picking the right density helps the system look natural once worn.

At NSY Hair, we offer 6 density levels, from “Extra Light” (60%) to “Extra Heavy” (180%). The right choice depends on factors such as your age, your natural hair density, and your hairstyle preferences.

(Image: 6 heads, labels: Extra Light 60% · Light 80% · Medium Light 100% · Medium 120% · Heavy 160% · Extra Heavy 180%. Alt = “The six NSY Hair density levels, seen from above”.)

H2: How Does Age Affect the Choice of Density?

Level	Density	Approximate Age
Extra Light	60%	60–75 and over
Light	80%	55–70
Medium Light	100%	40–60
Medium	120%	25–45
Heavy	160%	18–35
Extra Heavy	160%	18–35

These ages are guidelines and they overlap, because the right choice also depends on your natural hair density and your hairstyle. As we age, hair tends to thin, so a lighter density usually fits better. At a first purchase, it’s tempting to want very thick hair, but a more subtle look often blends in more easily with your own hair. If you’re unsure between two levels, write to us at support@nsyhair.com.

Depending on the base, some levels are not available: check the product page.

The Base Affects the Choice of Density

Not every density is available on every base. The densities offered for each model are shown on its product page.
