Using Henna on Dyed Hair
(St. Louis, MO)
If henna might turn chemically treated hair green, what do I use until it grows out?
I have not dyed my hair in months, just really busy and after hearing about bad chemical reactions I decided that I really did not want to risk it again... So I am researching about natural ways and from what I read Henna is the best. But I can't put it on already chemically treated hair... So what do I use or do in the meantime? Do I have to let the grey grow all the way out prior to trying the henna?
Thanks so much!!
