Well, I have seen it both ways in the past...and that is what is perplexing.
For example, in a SCS Exercise in 2013, we saw this:

While in a picture from 2014, we saw this:

In May 2014, at a stop in India, we saw a crew strapping down its helo like this:

But then in September 2014, on another vessel...we see this:

I do note that the two pictures seen here with no gear, though at different times, were both for helo 9224.
I hope we see some continuity and standard procedures fro flight deck crews going forward. Maybe they haven't had all of the equipment available. Maybe different commanders have discretion...I just do not know.
But there has been a big difference from one crew/vessel to another, even in the last three years.
Interesting, I don't recall these photos.
That said, I do believe that there are still a number of surface combatants, if not a majority of surface combatants which seem to lack head gear for their deck crew even while the helicopter is active, based on other videos and photos.
