Kylie Jenner can't dye her hair back to its natural colour because it is too damaged.

The 18-year-old reality TV star - who is obsessed with changing the hue of her hair - has reached out to her 11.7 million Twitter followers for advice on what shade she should go for next and she found baby blue to be the most popular choice.

Her natural colour is out because of the amount of dye damage caused to it.

Yesterday (05.10.15), she wrote: ''I really wanted to wear my natural hair but the front is so damaged now ... Should I stay black or go back to green or baby blue? ... I see a lot of baby blue (sic)''

Kylie - who is dating 'Rack City' rapper Tyga - recently confessed she has dyed her hair since was 16 years old and keeps changing styles because it makes her feel like a ''new person''.

She previously said: ''I first dyed my hair when I was 16. I dyed it blue and I never even asked my mom. After that, I've just had this addiction to changing my hair.

''It makes me feel like a new person. I love feeling different and I love leaving the house knowing that nobody has ever seen me this way.''
