Any home remedies for very dry hair besides visiting the salons?

This might sound weird but my mom did this to my hair because I really do have dry and damaged hair--putting mayonnaise and leaving it for around 30 mins to an hour. It actually helped in moisturising my hair and somehow it lessened split ends. I also experienced hair fall before but because of this, it reduced to minimal hair fall. However, since one remedy is not applicable to everybody, I suggest you still go for other tested natural remedies such as doing your own hot oil session at home. I also tried this before but what i did was to simply apply virgin coconut oil onto my hair and scalp then left it for about 30 mins. I rinsed it with warm water and viola--dry hair no more!
