PINK hair

 HI EVERYONE!! OK, so i am OBSESSED with pink hair. I have been going through a pink hair phase for a few months now and i need to have it done. My life will be sad until the day i have pink hair. I have spoke to a few different hairdressers and they seem to think it cant be done. I disagree... I currently have brown hair and light brown hair naturally. I have seen brunettes achieve pink hair by going white blonde first and leaving the roots brown. ( See pictures above! ) I've watched YouTube videos on this subject and all the girls lighten their hair first, then bleach until desired blonde, tone with a purple toner then mix a bright pink with conditioner to achieve a pastel dye. 
I wouldn't mind giving this a go but im SO afraid of damaging my hair and it falling out. GULP! I have very long thick natural hair so i don't want to ruin it. After all, it has took me 20 years to grow! I know this is possible and i hope to have a beautiful pink scone some day very soon! Does anyone have hairdresser friends or family that could give me some ideas or tell me which way is best to go about this? Make me happy! 

                 Love of love, M xx
