A real-life Rapunzel with 6.5ft-long natural, blonde hair who hasn't cut her locks in 30 years has revealed the secret behind growing her golden tresses. Alena Kravchenko, 35, from Odessa, Ukraine, said she only washes her hair once a week in a process which takes 30 minutes. The hair model never combs her hair whilst wet to prevent breakages nor does she use a heat to dry it, preferring to air dry her hair naturally.
