As of 2014, the cost of having two wefts of hair extensions sewn into natural hair averages between $225 and $300. The cost of a hair weave varies by region and stylist, and some can cost up to $10,000.
The stated cost of hair weave services may or may not include the purchase of artificial hair. Individuals should ask a stylist if the hair wefts are a separate cost. A stylist may charge more for weaving hair that is long or thicker than average, and people with longer hair may need additional hair wefts. Typically, sew-in extensions last about two and a half months.
