How can I redirect from one subsite to another in .htaccess?

I have (for example) site xyz.com

I would like to redirect xyz.com/series to redirect to xyz.com/products using htaccess

and anything after series to append to product for example xyz.com/series/{123} to xyz.com/product/{123}

I added this but, I have another subsite zyx.com, yxz.com which has same series and product after and this would affect those too which I don't want to.

-- --RewriteEngine On --Redirect 301 /shows/ /product/
