The one thing we know at LDL is Virgin Hair. Virgin hair basically means hair that has never been 'touched'; by chemicals, colour or any of multiple manufacturing processes that happen with factory made hair.
Virgin hair has it's cuticle intact- which means stronger hair for longer.
Factory hair is bleached up to 3 times, so the longevity is greatly compromised and cuts it's wear time down greatly. Hair that has been manufactured may only last 6 months- sometimes less - depending on the care of them.
With our virgin hair however, it has a minimum wear time from 3 years - right up to 5 years!
