I am doing a follow up from my last review as per my first experience, to my recent results.
My first review I stated that it absolutely works, but with patience. The first time I used Suntouched for dark hair was last year and it wasn't until the second bottle that my hair started to lighten.
This time around I had quicker results, despite the same hair fail scenario of dying my hair at home and ending up with dark brown hair -- lesson finally learned (hopefully).
My results are within a span of 1 month and still on my first bottle. I took the process slower this round because my first experience I was so desperate to have my hair lighter as quickly as possible and dried my hair badly. The left photo is from January 1st and the right is February 4 of this year. I did 3 sessions with outside sun exposure, 1 with the hair dryer and 1 with both hair dryer and then sun afterwards. After each session I did a hot oil treatment because I have extremely fine hair that can split and dry easily and this prevented any damage.
I bought the bundle so I still have another bottle which I will likely spread out using and see if my hair will get even lighter or if I've reached the maximum. Currently, I'm happy with the results which are a golden medium from dark brown.
