I had a dark pink that went into a baby pink over time. It was the first time i ever dyed/bleached my hair ever at 18. I did love my pink, but i got rid when i found out i was pregnant. I took 4 bleach baths and my lovely friend who spent 7 hours on it!!
You first off have to dye it blonde. Very blonde then put a lilac over it. Id use special effects, its amazing and its semi permant.
Its a lot of up keep for pastal colours as they fade very quickly. After a few washes it will look horrid
