What do you do with your hair?

I haven't straightened or blow dried my hair in years. I used to every day for work but Ihave been a stay home mom for 5 years and very rarely do my hair.

I was washing it every day, sometimes twice a day but recently my head has been so itchy and my scalp is super dry so I've decided to wash it every other day and I'm not sure it's making such a big difference.

Any recommendations?

I've tried head and shoulders in the past, thinking about doing that again.
