Suggestions for the girlfriend

[theGirlfriend]

Hello, guys. This is my very first post in the community. I hope you won’t find me out of place here!

I’m a girl, 24 years old, and my boyfriend, age 23, has MPB (dealing with it since the age of 16). He recently told me about his struggles with hair loss, how he's already had implants done and how he contemplates getting another surgery done somewhere along the next couple of years. We’ve been together for 1 year and I have always noticed how careful he is with his hair, but this conversation we had was an eye-opener. I never realized how his hair affected him. I feel a little odd bringing it up again, in case he might feel self-conscious and maybe even regret having told me in the first place.

This community seems to be pretty open about the issue, so I’d like to ask you all if you have any suggestions for me: is there anything in particular I could do or say to him to try and make him feel a little more comfortable in his skin? I’ve already told him his hair thinning doesn’t bother me in the slightest, but I certainly don’t want to brush off the issue as if it were unimportant; I want to make sure he knows that I am aware that it is an important subject to him, so I make it an important subject to myself.
Is it better for me not to mention it at all, unless he brings the subject up himself?

Also, I know touching his hair is a big no-no; is there anything else I should never do?

Thanks in advance for any help you can offer.
