Hey there, anwarjutt90!
Internal links are useful spreading link equity (or link juice, as you put it). While there is no definite answer on how many links you should include on a page, or exactly where they should be, I would encourage you to look at this from a user experience point of view. Do you want your users to land on this page, see the header link, immediately click on it, and leave the page? Would that be useful to them? If so, I would leave the link in place! But if exiting the page immediately will only distract them from consuming valuable content, I would consider omitting the link from the header, and putting it somewhere that's more useful.
Also remember - internal links are useful for establishing site architecture! So if the pages you are linking TO are important, perhaps you should consider moving them up in your site architecture.
