Hello,
I had nice blonde hair before my hair transplant. I've been taking finasteride and minoxidil for over a year each and neither have darkened my blonde hair, however after the transplant my blonde hairs did not grow in blonde again.
I understand that my donor hairs may be darker in color than the recipient hairs, but none of it has lightened with time.
How soon after a hair transplant is it safe to try non corrosive lightening products? I am looking at this lightening spray in particular: https://www.amazon.com/John-Frieda-Lightening-Controlled-Chamomile-BlondMend/dp/B004DK7DVC
I am not interested in using a real hair dye, so I am hopeful that there are other ways to get my hair lighter/blonder again.
