Hey Guy9102
First, congrats on the new hairpiece.
It is common for black hairpieces to develop a reddish tinge after a while. This is usually caused by the sun degrading the dye used to colour the hair (nearly all hair system hair is bleached white during the manufacturing process and then re-dyed to the required tone). It is easy enough to fix. You just need a colour-correcting shampoo or conditioner. These are products with (in the case of black hairpieces) a green tint, which cancels out the reddish tinge and returns the hair to the correct black colour. It doesn't harm the system in any way. You can find colour-correcting products in supermarkets and pharmacies (women who dye their hair have the same problem), or you can get them from specialist hairpiece suppliers like Hair Direct, or from Amazon.
Assuming you haven't spent a lot of time in the sun since you got your piece, the problem you have is slightly different - simply a bad initial colour match. You could go back to the salon where you got it and get them to correct it (which is what I would recommend), or you could correct it yourself using the colour correcting products. The neon lighting in most salons can be deceiving, and does not always give an accurate impression of what the hairpiece will look like in natural sunlight. It is worth going outside with a mirror to check that you have got a good match.
This problem does not necessarily mean your piece is bad quality - it could just be that the stylist made a poor call on the colour match. But if you find as you are wearing that it frequently develops that reddish tinge, that is a sign that the manufacturer has used lower quality over-processed hair. Hopefully that will not turn out to be the case.
