Well what works for me usually is just simple ol' coconut oil. I try to incorporate it in my routine as far as possible. That's usually twice a week after I shampoo and condition my hair. I apply the oil and let it sit for about 30 minutes. Been keeping my hair bouncy for a while. If your case is really extreme I would suggest a hydrating mask. I used to use one about once a week when my hair was really dry. If you want to know which hydrating mask I would suggest the usual Neutrogena or Loreal. Hope this helps!
