Hair baldy patches and colouring product.

I have a small bald patch that has appeared in the last year and I have just had a biopsy done on it. The doctor suspects Lichen Planus. In the meantime my roots are growing out bigtime! I have just turned 60 and have been blonde all my life thanks to Clairol so wonder if continuing to be so will do damage long term? Has anyone any concrete information on this?

hmm...interesting question.

do you trust your hairdresser? they may be able to answer this, since sometimes they learn about hair structure etc. or the pharmacist?

Better to get a consultation from a hair transplant surgeon. He may help you in this matter?

Ask yo about hair colors that are not toxic. 

Coloring hairs cause hair loss and create so many hair related problems. So take care of it.
