How to fix this problem?

I'm trying to take pictures for my makeup portfolio. I've played around with the settings, tried natural lighting and artificial, etc. The best way to capture the colors is to use flash, but the problem is that it makes my eyebrow makeup look orange. I use Manual or Portrait and besides that problem, the pictures turn out great. I'm using a Nikon D5000 and also editing with Adobe Lightroom 5.

If you could give suggestions on how to either fix this problem on my camera or how to edit in Lightroom, that would be great.

If you are getting color shifts, you need to either consider setting a custom white balance in the camera, or shooting RAW and adjusting the white balance in Lightroom.

Check you camera user manual, it will tell you how to make a custom white balance.

Shoot in RAW and then use Lightroom to process them all.

As far as the colour of the makeup not coming out true, you may find that you need to create a custom white balance. I use a Xrite Colorchecker Passport to assure that all the pigments found in makeup and textiles are recorded as closely as possible.

If you are going to use flash, make sure that the flash is NOT on the camera. The type lighting that an on-camera flash produces is rather harsh and will not show the contours of a persons face well

Instead use a key flash at about 45 degrees to the face and if you do not have a second flash, use a piece of white poster board to add some fill to the shadow caused by the flash

RAW is your friend then adjust WB in post like Lightroom or ViewNx.
