Hi again!
Maybe I was late for the retouching black hair class
Thank you superkoax and admirer great advice!!
I have copied one of the images from a tutorial to try to improve this technique of giving life to black hair. I still notice that some color interpolates as a follow you guys' techniques. I have tried desaturation but I have not had any luck.I will continue though. Check it out!!
I know there are a lot of people here more advanced in this technique, believe me some of us know solutions in a more specific way so I would like to thank you for your replies. Whatever they may be, they will help. Thank you!
