For a natural look, hair extensions should be only a few inches ( less than 4inchs 10cm) longer than your own hair. If you have short hair and need to add hair volume and length ( more than 4inchs) at the same time, at least you need to buy 150 grams, so that your hair ends will look natural and not thin.
* If you have short hair( less than shoulder length), want to add length & volume, buy 4 lots please ( 80 pieces )
* If you have long but thin hair, want a more volume look, buy 2-3 packs please (40-60 pieces )
* If you want a highlight/balayage ombre look or just adding hair volume, buy 1 pack please ( 20 pieces )
