Hi.
I had to read your OP again to clarify the problem and I think it is how the hair looks ion the morning yes?
I have the same curls, same length.
Sulphate free shampoo, As I Am Coconut Cocowash from Amazon alternate weeks, its a conditioner wash and doesn't strip the hair.
On other weeks use just a normal sulphate free shampoo, not a co wash.
This will make the condition better.
Deep conditioners with a bag on, hour at a time if she can.
No hair drying. Blot using one of those special towels.
Comb in shower with conditioner on.
Leave in conditioner and a bit of oil when it's almost dry, coconut will do.
Leave to dry.
That's my washing routine and it means no heat, no stripping, no over use of chemicals and no crap styling products.
Every morning I turn upside down and use one of those curly hair comb things, long ones. Can't remember the proper name! Comb from the roots to give volume.
Then a bit of leave in container, I use the hair food ones, only a fiver from anywhere. A bit of that and stick hand under tap to get hand wet, hair upset down and scrunch into the ends. Then stand up and slightly wet the hair, stroking with a wet hand from the tap. This puts water and moisture into the hair and tames frizz.
I then use two little clips to give two little pull backs, one above each eye, to keep it out of the way. This way it is out of my face but still pretty.
Curly hair isnt easy is it!!!
