Change of colour and advice needed

Samantha • Ohana means family and family means no one gets left behind or forgotten.
Thought I would join in on the craze before Christmas and I went a silvery colour on the bottom then a pink on top and it faded like so quickly that it looked tacky! I wanted to let my hair grow its natural colour but I've dyed it to its natural colour anyway. So happy with my hair colour now and it looks normal. Just for the growing process now. Any amazing tips on growing hair cause I hate how short it is?
