Mermaid Hair Is For Celebrities and "Virgins"
I tried for 10 years to have perfect long blonde hair before I realised I just don't have the money, patience, or hair type for it. It's either long, or it's blonde, but without hours spent bathing in intensive conditioners and sitting in pain at the salon as two juniors play a game of "who can detangle the fastest," it can rarely be both.
Most people with very long hair either keep their natural "virgin" hair colour, opt for highlights or balayage rather than all-over colour, or boost the length with hair extensions. It's rare to find someone who has hair that's long, coloured/bleached, and in good condition (I salute those who do). For now, I'll stick to my mid-length, mid-blonde compromise. Sadly, you can't always have it all.
