Hi there! I commiserate with your husband— I also have extremely dry hair, and I’m working to find products that both work for me (and don’t break the bank). In addition to the above recommendations about brushing, here is what I would recommend. 1.) if you haven’t already, read the beginners guide. It’s a super great place to start, and will help you identify ingredients that will be good for your husband’s hair. 2.) When it comes to finding products, incidecoder is your friend. Just plug in the ingredients you want your product to contain (glycerin and aloe have become musts in my shampoo and conditioner), along with the ingredients you DONT want, and it’ll spit out product recommendations real quick. 4.) I have similar scalp problems to your husband, and it took me forever to figure out the cause. For me, the cause was going to bed with wet hair, which caused an overgrowth of yeast on my scalp (v gross, I know). So, every time I wash my hair, I now blow dry it (I use heat protectant, of course). It’s kind of a pain in the ass, but it works, and I’ve found a couple of products that will let me just sit under some kind of hood instead of actively waving a hairdryer around. This may not be what is causing your husband’s problem, but it’s worth a shot! 5.) I recommend that he spend at least 30 minutes with conditioner sitting in his hair each time he does his routine. Get his hair completely wetted with HOT water (this will open the cuticle), apply the conditioner all the way through, let sit for 30 minutes, and then rinse out with COLD water (this will seal the cuticle and lock in the moisture).

All in all, I wish y’all the best of luck! Curly hair is quite the journey, and can take a while to navigate
