As the Henna for Hair girls suggested, after three washes and going swimming, my color did fade to a warm strawberry blonde.
I do like this color, however, I still have as much henna left as I used the first time, so I might have to go even redder sometime this summer. What can I say? I got a taste and I’m craving more. Thankfully, henna is actually good for my hair so I won’t feel bad mixing up the paste again in a week or so!
