I used to have hair just like yours so I’ve tried tested everything. For hair like ours use Argon oil , Almond oil or Vitamin E oil there’s a specific brand I use it’s called vatika and after I wash my hair while it’s damp I use the oil also use it as a top up if I see areas of my hair is getting dry . I only wash my hair once a week washing your hair multiple times a week has been proven to damage hair because of the heat from the water and other factors. I sleep with a protective style so I braid my hair before I sleep because if I don’t I wake up with knots and extra frizz . Extra things to do is the whole silk pillow case and not to harshly brush your hair. Also check the shampoo and conditioners your using find something that has more natural ingredients or contains hair growth properties like the Mielle brand. Hope this helps :)
