how much for hair
1 Total cost ranges from $1,600 to $4,000. 2  High-quality human hair that is cut -- not brushed -- off usually costs from $250 to $500 for a partial head and $1,000 to $2,500 for a full head, depending on length and origin. 3  Synthetic hair and low-quality human hair, which are not recommended, cost much less. As hair grows, hair extensions will need to be taken out and reapplied; hair extensions usually last an average of four to six months. 2  This re-application will cost as much as the first for labor, but high-quality human hair usually can be reused.
