Henson cannot hold down a regular position in the Ospreys side and, on current form, would struggle to make the Wales squad for the autumn Tests.
Davies, in his time as an international in both codes of rugby, has 'been through all the pitfalls that are out there' and is ready and willing to help.
He has complete faith in Henson and is convinced he can return to the stunning form of 2004-05 in time for the World Cup..
Davies explained: 'If any player wants to talk I am always there.
'I love my rugby and I look at it differently now than when I was playing. I look at it analytically.
'I think I know what he is going through because I have been through most of the pitfalls. When you are up there and things aren't going well it is very, very tough.
'As a rugby supporter, I know what he can do and I know what he is capable of."
Henson hardly played last season as he recovered from a groin injury and then served a suspension for elbowing prop Leicester's Alex Moreno.
But Davies believes Henson is just one of his famous dump tackles away from an immediate upsurge in confidence and form - but it will need work and change in mindset.
'Everything has been said for his celebrity way of life and his partner - but to me that is immaterial,' continued Davies.
'He is a total professional. His body is a temple. He trains hard, he is very focused on what he does but he is not performing on the field.
'I think he should have gone on the summer tour to Argentina instead of taking it off. It took the players out of their comfort zone.
'When the team is not performing it is difficult to raise your own game but at the moment his body language isn't right.
'When things aren't going well you have to put yourself about a bit. He has to look for opportunities and he has to take games by the scruff of the neck.
'If he can do that things will turn around. One tackle could change his season."
