Hello!

I’ll try to keep this short.  
I want slide 4’s color.  
But I’m on a budget and want to do it myself. The best thing I can think of is some type of lightener that you use gradually like each shower because I’m 1. Too scared to use bleach as a newbie and possibly go bald and 2. Am not looking forward to having to retouch roots—so if there exists a gradual lightener, it  would solve that if I concentrate the lightener  near the roots?  
This might be a dumb question but I really want to know if there’s such a product that I can use weekly or biweekly that will lighten my hair to a light blonde over a few months that I can later space out using when I like the color.

I think I know I would prob have to use a toner to let that pinkish undertone for slide 4. I also kinda just added 5 as reference that I want a pink blonde specifically not the yellow necessarily.

It’s always been my dream to have that hair color so if it’s not possible without hardcore bleach than I’ll still do it and would appreciate advice on getting that color as well anyway. Just trying to see if what I have in my head exists somewhere. Sorry if it’s a dumb question!

Hair info: Slides 1-3 are pictures of my hair in different lighting. Number 1 is my natural hair color without highlights, in 2 and 3 I got highlights. I have naturally wavy hair which makes it frizzy if I don’t condition and dry it right. I heat style often but try to keep hair healthy otherwise.

Need hair lightening recommendations!!
