I used to use 18 inch hair and most of the 4 ounce wefts that I purchased were between 46 and 60 inches in width.
What to consider when ordering hair (human or synthetic)
Hair comes in a pack weighing approx. 1/4 pound (or 4 ounces)
For a full head of hair extensions to be installed, approx. 8 0z of hair is used
(based on hair length of 16-20 inches)
Two packs of hair at 1/4 pound would be a total of 8 ounces of hair or ½ pound needed
1KG=2.2 pounds
16 ounces of hair is one pound of hair
4 ounces of hair is 1/4 pound of hair
8 ounces of hair is ½ pound of hair
How many inches in width would be equal to a pack of hair? (1/4 pound or 4ounces)
One inch = 2.54 cm
12 inches = 1 ft
36 inches = 1 yd
3 ft = 1 yd
