Help needed with hair!

I am trying to change the colour of a persons hair in photoshop cs4. I have managed to colour everything fine apart from the hair that hangs over the forehead.

I have tried using a thin brush with my wacom and drawing over them, but to be honest it just does not look natural!

Does anyone know of a way to re-colour these thin strands of hair so that it looks natural? Any help or advice greatly appreciated!

Hallo Fuzquia,

an image would help a lot ;-)

I think your problem is to create an accurate mask - as you already have changed the haircolour in the rest of the image.
If the colour of the existing hair is blonde you will have much work on a light skintone.
Try a brusch with formfeature - look at the .png. That together with a graphics tablet should work fine.

Good luck!

Re: Help needed with hair!

It depend on the image and the color of the hair and its background. Creation of a good mask will allow you to isolate the hair so you do not need to brush each strand. Use of a gradient map may be sufficient to recolor all the hair at once but it deepends on the before and after colors. You may want to attach a sample of the image for members to look at and provide you with specific suggestions.

I think he meant a picture of the hair you want to colorize.
For example if there's lot of contrast between the hair and the skin you could use the channels to create a mask to select just the hair and colorize them afterwards.

Edit: It's just like in German forums, I'm as always too late :-D

Hi, sorry I had to go out there for a short while. Didn't think I would replies so early!? Thank you for this.

Sorry I never thought to attach an image, how dumb! What do you think? Some of the strands are sooo fine. Think to mask is my only option?

Re: Help needed with hair!

Do you have a larger photograph like this? Because it seems like a mask wouldn't be to hard to create (although the upper part of the head would take a little more time to work on).
Have you ever created masks?
Basicly you try to figure out, which channel contains the greates contrast between your foreground image (in this case the hair) and the background and try to make it almost black and white using Levels and the Dodge and Burn-tools ([O]). After you've done your mask you [Ctrl]/[Command]-Klick on the masks icon to load it as a selection and use it to whatever you want.
