Doesn't sound as if your conditioner is doing the job at all well, you may need a different one, preferably one with 'smoothing' qualities - these are usually sold with a description along the lines of 'sleek and smooth'. Maybe you're using a high detergent level shampoo too - when you choose a shampoo, smell it - those with high detergent levels can be detected by the nose and smell a bit like washing up liquid and should be avoided. This only works if you have a reasonably good sense of smell, obviously, and men often don't have (no criticism, just a fact) so maybe ask a woman to smell it for you if that's the case for you. Expensive shampoos MIGHT have less detergent, but not necessarily. Either way, pick a shampoo that's gentle (sniff those too, even shampoos for babies vary), wash the hair and when you condition, and using a wide tooth comb, comb the conditioner through and leave it on for 10 to 30 minutes, then rinse off.
This next part is the only bit that might fit into the 'Hack' category, because you might have it in the kitchen cupboard already. Ordinary coconut oil is a good restorative for use on dry, rough hair, but use it on dry, not wet, hair - warm it slightly to melt it, and apply liberally to all the hair, wrap the hair round your head and then wrap in a towel or cling film, leave it on all night, wash and condition as usual the next day. You may find you need to wash it twice to clear away the oil. Repeat this treatment periodically, when you notice your hair looks dry and rough again.
