hi im holly

and im a natural light blonde

but i got bored with it so my friend dyed it black and i loved it and my hair was really thick and long but then i got bored and missed my blonde so i dyed it back and i have dyed my hair 7times in 3 weeks and its all dead and i had to get it all cut and when its wet it feels like elastic bands and it kept falling out and the sides of my hair is way shorter than the back of my hair and know i have to wear extentions but what can i do to make it grow and be thick and heathly but still stay blonde

thankss x
