Yes. Reapplication can be at any time but it would be highly inadvisable to do so soon after two refusals without expert advice to confirm that any corrections are likely to be suitable.
The chances are such advice already exists somewhere within Travel but if no Q/A already covers your friend's situation you of your friend might care to post images (with personal details suitably redacted) of the refusal letters for review here.
